“A Day to Change an Entrepreneur’s Future”: The Frenzy Behind the Scenes of Venture Ecosystem Summit 2025 – Part 1

  • Interview
2026.02.17

For this article, we interviewed President Goto, the organizer of Venture Ecosystem Summit 2025 held in October 2025, along with the operational committee’s three leaders.
(This interview was conducted in December 2025.)

◆ Reflections on the Event

Sugihara:
Today, we are joined by President Goto, the organizer of Venture Ecosystem Summit 2025, and the operational committee’s three leaders, Mr. Shibata, Mr. Matsutani, and Ms. Kawaguchi.

First of all, a huge congratulations on the massive success of the event! The feedback from participants has been overwhelming, and as a participant myself, I truly enjoyed it. Now that this major effort is finished, could each of you share your honest feelings?

Goto:
Right now, I am simply filled with a sense of relief. To be honest, entrepreneurs have very discerning eyes. Even if they say “It was great!” out of politeness, they’ll tell you clearly by their expressions if they don’t really mean it. They are the type of people who will give you direct, unreserved feedback if there is something they aren’t satisfied with.

We successfully held an event that satisfied entrepreneurs with such strict preferences. So in that sense, we gave it our all, and now we can give a big sigh of relief.

Sugihara:
I’m sure you really put your whole effort into this. Did you happen to fall ill or run a fever after the event ended?

Goto:
Fortunately, I didn’t get a high fever, but I did collapse for a moment, ha ha. I must have been so tension leading up to the event because the next day, I had a feeling of exhaustion that I can hardly even put into words. I was just completely wiped out.

Sugihara:
I’m glad you were able to recover from that! Next up, Mr. Shibata.

Shibata:
I feel very similar to President Goto, but if I had to sum it up in two words, they would be ‘frenzy’ and ‘relief’.

However, my sense of relief is slightly different in nature from what President Goto shared. First and foremost, as part of the operational committee, there was the relief of simply getting through the entire event without any major issues.

Secondly, I was assigned head of the operational committee. During the preparation phase, I placed a fair amount of burden on the other operational committee members, and there were moments when things didn’t go as planned. So when I heard everyone saying “It was a wonderful event” after it finished, I felt a weight finally lift off my shoulders.

Looking back, I feel like that entire period from preparation to the actual event was pure frenzy.

Sugihara:
Everyone was so energetic, they almost seemed to be glowing from within. Mr. Matsutani, how about you?

Matsutani:
At the moment, my heart is welling up with a quiet sense of total fulfillment. While listening to Dr. Semmoto’s lecture and President Goto’s closing remarks at the end of the event, I was moved beyond words.

I felt so glad we were able to hold it in the manner that we did. It felt as clear and refreshing as the moment after listening to a profound and beautiful symphony. From the overall balance of the venue to the almost physically perceptible heat and power radiating from the speakers and participants, I truly felt incredibly glad we made this event happen.

Additionally, every single staff member performed their parts wonderfully. It was impressive to see how everyone embodied our core value of empathy right there at the venue.

Goto:
The participants also complimented us frequently on the staff’s performance. My impression is that paying such close attention to even the smallest behaviors of the staff is entirely to be expected of business owners.

Some staff members were standing at various points along the route from the station to the venue holding guidance signs. Working outdoors in that capacity is much harder than people realize. The CEOs even noticed even those behind-the-scenes efforts and told us, one after another, that the management was truly superb. From the meticulous care inside the venue to every interaction, the team’s response was consistently magnificent.

Sugihara:
Thank you. Now, Ms. Kawaguchi, your thoughts please.

Kawaguchi:
Like everyone else, my first sentiment was relief that the event was held without incident. Even though it was only October, I felt a massive sense of accomplishment, as if I had already conquered the whole year.

Actually, preparations for this event started back in December 2024. We began by inspecting various potential hotels, but just securing a booking was already becoming difficult, so right from the start, we were scrambling to coordinate dates. Because of those circumstances, I feel like I was pouring 100% of my energy for the entire year into this.

This year, I’ve been running with the singular desire to build up anticipation for the Venture Ecosystem Summit and make it a success. Now, I’ve been feeling this comfortable sense like I don’t have to do anything more after finishing my biggest mission of the year, even though October might’ve been a bit too early for that.

◆ The Purpose Behind the Event

Sugihara:
You were preparing for a whole year, indeed. From a participant’s point of view, I felt it was a wonderful event that directly conveyed President Goto’s passion. Could you tell us again about the background and reasons why you decided to hold the Venture Ecosystem Summit?

Goto:
D-POPS GROUP holds an all-hands meeting at the end of every year, and we always ask our chairman and co-president Dr. Sachio Semmoto—the co-founder of KDDI—and our corporate advisor Ichiro Fujisaki—former Ambassador to the U.S.—to give a speech there. Every year, I feel something extraordinary in their words that truly shakes the soul.

Then, I had the sudden thought: it would be a travesty to society for us to keep such a valuable experience contained only within our group. My primary motivation was the desire for all entrepreneurs, who are currently tackling their own issues with their best efforts, to have the opportunity to see, hear, and feel these two individuals speak, rather than keeping it behind closed doors.

At the same time, we are working to build an unprecedented Venture Ecosystem and a platform that serves society, so I also wanted more people to know about our approach.

There are many systems to support startups in the world, such as VCs, angel investors, or aid from national or local governments. However, the current reality is that these support systems are rather compartmentalized, so I don’t think a platform capable of providing 360-degree support from every angle exists yet. Of course, neither is D-POPS GROUP able to supply the perfect platform, yet. But I want to reach a point where the entrepreneurs and members involved in this Ecosystem can truly feel, “We are building the world’s first platform of its kind.”

To clearly communicate that vision to the world, this was the best timing. When you gather that many entrepreneurs, their effect as influencers is immense. If one participant tells ten people, it spreads to thousands instantly. I am convinced that conveying the significance of the ecosystem to these brilliant entrepreneurs carries massive weight for our future development.

Sugihara:
I see your point. In a typical event, even if you gather 1,000 attendees, the reality is that some are only there because their company ordered them to attend, and others lose focus halfway through. However, at this seminar, every single participant was a business owner. I was overwhelmed by the high level of consciousness in the room—everyone was there to learn and absorb something from that day.

Goto:
In fact, every single guest there was personally invited by me. There are so many passionate, hard-working people around me that I really wanted to invite so many more, but the venue was already at maximum capacity. Because of that, the chosen participants approached the event with extraordinary energy. I believe the temperature in that room was only possible because such highly ambitious people gathered there.

Sugihara:
The participants were exceptionally growth-oriented. Mr. Shibata, as the person handling customer relations on that day, how did you feel that energy on-site? Also, were there any specific challenges in managing the event?

Shibata:
The word frenzy I used earlier refers exactly to the heat that was in the room. To be honest, in my line of work, I have many opportunities to attend various study sessions. As you mentioned, it’s not uncommon to see people who clearly look like they are just there because the company told them to be. But at this event, looking at it from a management perspective with a bird’s-eye view, the sight of the participants never looking away for a second—everyone with their heads up, staring intently at the speakers—was incredibly striking. Even from the back of the room, I could feel the raw intensity of people thinking, I will learn everything from this moment and absolutely apply it to my company. If it was that strong in the audience, the people on stage must have felt an even more powerful energy.

Regarding challenges…it turned out to be a needless worry in the end, but during the planning stages, President Goto and I spent a lot of time strategizing how to keep business owners focused. Entrepreneurs are often strong-willed and independent, so we were meticulously obsessed with every detail—content that wouldn’t let them get bored, the order of speakers, and precise time management. However, once we opened the doors, we found the very people President Goto invited out of genuine trust. Both the speakers and participants were people who held the same values of “sincerity, humility, and gratitude” as we do, and everyone participated as if it were their own personal mission. I had been bracing myself in case we encountered any difficulties, but it turned out so smoothly it was almost anti-climactic. That was the biggest surprise and the point that left the deepest impression on me.

◆About the Speakers

Sugihara:
The lineup of speakers for this seminar was truly prestigious. (Click here for a detailed list.) How did you manage to request lectures from world-renowned Japanese figures such as Dr. Semmoto and former Ambassador Fujisaki, and what were the participants’ reactions?

Goto:
First of all, I think many people felt they absolutely had to attend just for the chance to hear Dr. Semmoto and Ambassador Fujisaki speak. The members of our company understand well how priceless their stories are, and the same goes for most founders. Dr. Semmoto is someone every striving entrepreneur wishes to hear in-person at least once. On the other hand, someone like Ambassador Fujisaki—who was at the forefront of diplomacy and international affairs as the former Japanese ambassador to the US—is someone even business owners rarely have the chance to encounter in daily life.

However, the world is currently in a state of upheaval. Now that the movements of superpowers like the US and China directly impact business, entrepreneurs have their scanners set to detect the slightest movement. Therefore, they definitely sensed the need to learn Ambassador Fujisaki’s perspective. Once these two speakers were confirmed, I was certain we had a rock-solid foundation for the event’s success. That’s why they were the very first people I decided to ask during the planning phase. When I consulted Dr. Semmoto, he gave his immediate consent, saying, “This is a wonderful endeavor. I will definitely participate and offer my full cooperation.” You could really feel from their presentations on the day that both of them were sincerely trying to deliver a message to the entrepreneurs in the room.

Sugihara:
In addition to the speakers we’ve discussed, you also had Shinichiro Naito, President and CEO of Findstar GROUP Co., Ltd., and Shoichi Motodaka, Executive Vice President of NTT Docomo Business. How did it go when you reached out to them?

Goto:
President Naito serves as Non-Executive Director for our company, and Vice President Motodaka is a close personal friend, so both accepted the invitation graciously. However, precisely because we have such intimate relationships, I intentionally set the bar very high for them.

I knew the audience would consist of highly sensitive entrepreneurs. So, while President Naito has spoken at countless seminars and study groups, my request to him was to present something in-depth that he has never spoken about anywhere else. I had him submit his materials in advance and requested specific adjustments to reflect our intent. Because he is like an older brother to me, I was able to make such demands, and I believe that’s why he rose to the occasion.

To ensure the participants were happy and satisfied, the overall layout of the program was vital. I treated it like a puzzle, making sure every piece was of the highest quality and carefully curated so that none of the content felt repetitive. I endlessly asked myself the question, “What is the specific piece that today’s entrepreneurs are missing?”

For example, if another CEO with a 10-billion-yen company were to give a similar talk right after President Naito (who has built a business of the same scale), the content would feel redundant. That’s why I was certain that the necessary piece we were missing was a perspective from a large-scale corporation. I felt Vice President Motodaka, whom I respect deeply as a human being, was the perfect person to fill that role.

Sugihara:
It sounds like every single element of the program was calculated with extreme precision.

Goto:
I put an incredible amount of thought into it. That also applies to the soul-stirring pitches by the young founders and the performance by calligrapher Yuuna Okanishi. Initially, we planned to have Ms. Okanishi perform at the end, but after repeated team discussions, we decided to move it to the very beginning.

By starting with a highlight-worthy performance, we were able to instantly sharpen the atmosphere and focus the participants’ attention. Even CEOs who might usually act a bit restless were sitting up straight and listening intently that day.

Ms. Okanishi doesn’t just have unbelievable stage presence, she has a wonderful persona, and the venue seemed to be filled with her positive aura. By the way, of the two panels she painted during her performance, one is displayed here in our Shibuya Hikarie office and the other was given away in a raffle. The panels were so popular that after the event, people were even asking us if they were for sale, ha ha!

◆The Inside Story of the Arrangement Process

Sugihara:
That performance was indeed spectacular. Ms. Kawaguchi, I heard that you were in charge of procuring the production materials and coordinating with the calligrapher. Were there any particular aspects of making that performance happen that you had to figure out yourself?

Kawaguchi:
When President Goto first mentioned he wanted a calligraphy performance, the scale I initially imagined and what he was envisioning were miles apart, ha ha.

I thought to myself that it would be maybe a meter high. But when we started discussing the details, he pointed to the large unicorn panel on his office wall and said, “I want it twice that size—about two meters tall.”

I had to double-check with him several times: “Are we really making it that big?” We actually took out a measuring tape, and eventually, we concluded that the impact factor of a two-meter panel really was absolutely necessary.

However, when I went to order the panels, I couldn’t find a vendor capable of custom-making panels of that size. Most told me, “We’d have to join two panels together,” or “We can't guarantee it will stay upright.”

In the end, I reached out to Best Support Systems, the company that handled our office’s interior design, since they had created all our unicorn panels. I was unsure about asking an interior contractor for just two panels, but they accepted gladly. They worked with us through countless revisions—not just on the size, but on fine design details like the placement of the unicorns’ heads. That performance would never have happened without their earnest cooperation, and I am truly grateful for them.

The panels were a massive hit. Some CEOs asked me to introduce them to the manufacturer because they wanted to use them for their own events, and even Ms. Okanishi wanted to know more details about the material because it was so easy to write on.

Sugihara:
For a seminar packed with so much content, I imagine the logistics and same-day preparation were quite a challenge. I heard that Mr. Matsutani, who was in charge of organizing the proceedings, woke up at 3:00 AM on the day of the event to finalize the production schedule. What specific points did you focus on while managing the flow of the event?

Matsutani:
President Goto had a clear vision of creating “a day to change an entrepreneur's future”. I saw my role as figuring out how to translate that passion into a concrete, actionable form. Something to avoid at all costs in event management is breaking the participants’ concentration due to logistical delays. I focused primarily on how to allow the attendees to totally immerse themselves in the content without feeling any unnecessary stress.

While President Goto designed the overarching flow of the event, I obsessed over the fine details, from the guidance routes for moving guests from the auditorium to the reception hall, to the operational committee members’ positions, and even to the exact layout of the catering tables. And then I poured my soul into how to accurately share these details with the entire operational committee and ensure they all moved in sync.

Actually, in my student days, I experienced managing presentation events for a thousand people. Since I was still young back then, I’d prepare for two days straight, without even a wink of sleep. I can’t quite do that anymore, as a working professional, ha ha…so I took a two-hour nap from 1am to 3am in the middle of the night before the summit, and then got to work on the final touches.

I sent the draft script to our emcee, Ms. Hida from Talk Navi Inc, two days prior, but I didn’t get the final version to her until the morning of the event. Despite such a tight schedule, Ms. Hida was incredibly flexible with same-day changes and corrections, supporting the proceedings with an outstanding sense of stability. I have nothing but gratitude for her.

Sugihara:
That’s true, I didn't see any of the typical mistakes or mishaps that usually occur in an event of this scale.

Matsutani:
It’s not like we didn’t have any mistakes, ha ha…to be honest, we didn’t even hold a full technical rehearsal beforehand, so as for myself, I feel everything went miraculously well. We also did the final checks for the slides and other things on the morning of the event itself, but we were only able to pull that off thanks to the immense cooperation of the venue staff. The venue manager even came by to observe and gave us a big boost of encouragement by saying, “This is truly a wonderful event.”

[Founder Interview #6] Hiroshi Yamaguchi (Aoyama-Itchome Chiropractic Clinic) – Part 2
The Body is an Executive’s Precious “OS”: Maximizing Productivity by the Investment of One’s Posture In this second part of our three-part interview, we dive deep into the profound impact that loneliness and mental stress can have on executives’ physical bodies. We reveal the striking parallels between a professional’s perspective—analyzing patients’ walking style, facial expression, and tone of voice before they even sit in the chair—and an investor’s evaluation of an entrepreneur’s “human OS”. Director Yamaguchi also shares the fundamental, biological truth that posture and facial expression mutually reinforce each other, and he opens up about the exact moment that set him on his lifelong path to chiropractic medicine. (This interview was conducted in March 2026.) If you haven’t read Part 1 yet, you can do so here. ◆An Entrepreneur’s Body is Like an “OS”, and Posture is an Investment towards Maximizing Productivity Sugihara: I believe this topic is incredibly vital for young entrepreneurs in the IT and tech sectors. Many of these founders belong to a generation that has had a smartphone in their hands for as long as they can remember. Could you break down what happens when you have poor posture in a way that speaks directly to them? Yamaguchi: As I emphasized earlier, I want leaders to view correcting their posture not simply as a health routine, but as a direct investment to ensure the success of their current business—an investment to maximize their productivity. For corporate executives and others who work in startups, your physical body is like your OS (Operating System). No matter if you have amazing software (i.e., your skills and strategies), they’re meaningless if the underlying OS isn’t running smoothly. That OS is your own body. Sugihara: Right, if the OS is full of bugs, you won’t be able to realize the framework you’ve envisioned in your head, even if you have great apps. Yamaguchi: Precisely. While your health is not all about posture, posture is still a deeply important part. That is the exact message I want to convey. ◆Stress Stiffens the Body: the Mechanism of Mental Fatigue Sugihara: Within D-POPS GROUP, we have 25 group companies and have invested in about 30 other portfolios. Their leaders are all working incredibly hard across various fields to solve pressing social issues. However, various forms of pressure—such as cash flow issues or HR problems—start to hit once people step into an executive role, yet many find themselves in a position where they can’t talk about it with anyone. Call it the loneliness of leadership if you will, but they have to persevere while carrying burdens they can’t share. Does this kind of condition easily contribute to physical ailments? Yamaguchi: There is physical fatigue, which comes from holding up or carrying something. But there is also mental and emotional fatigue; the exhaustion caused by constantly having to be overly mindful of others, the pressure of endless problem-solving, or being caught in the middle of conflicting parties. This also can cause muscles to stiffen. In fact, while physical fatigue can be relieved to some extent by moving and stretching, mental fatigue often causes a greater effect on the physical body. Take the old Japanese idiom, “Drowning in debt so deeply your neck won’t turn”. Continuously worrying about something or experiencing hardships one after another causes your neck and shoulders to become incredibly stiff, leading to insomnia, migraines, etc. People in ancient times were purposely verbalizing those exact physical symptoms. That phrase describes one of the classic physical symptoms triggered by extreme stress. When the idiom was coined, the word “stress” didn't even exist, but to put it in modern terms, “stress physically prevents your neck from turning”. I once treated a CEO from a foreign company who didn’t know much Japanese. Suspecting that his chronic headaches and neck pain were purely stress-induced, I asked him in English, “How do you like your new boss?”, to which he replied, “He’s a pain in the neck.” In Japanese, the equivalent phrase would directly translate to ‘He hurts my head’, but it’s clear that in both Japanese and English, people express the biological truth that stress targets the neck. ◆Cranial Nerves Directly Affect the Neck and Shoulders: the Biological Mechanism of Stress Sugihara: So, continuing to internalize all that pressure will impact the body. Yamaguchi: Exactly. People who spend an entire day working alongside someone they have to tiptoe around or completely clash with, they’ll often have stiff necks and headaches by evening, even if they weren’t sitting down. That isn’t physical exhaustion; it comes entirely from emotional fatigue. The reason for this is that most movements below the shoulders are controlled by nerves originating from the spinal cord—a body part with no emotions—so no matter how mentally exhausted or stressed you are, your arms or legs won’t suddenly refuse to move. However, motions in the head, neck, and shoulders are connected to the cranial nerves, which emerge directly from the brain itself, which processes your emotions. Mental stress, anxiety, frustration, and worry travel directly along those nerves, causing the muscles in the neck and shoulders to immediately tense up. There are 12 pairs of cranial nerves. Among them, the 11th pair—known as the accessory nerves—directly stimulates the major muscles responsible for moving the neck and shoulders, such as the sternocleidomastoid muscle. When this specific nerve is compromised by emotional stress, your neck won’t turn and your shoulders become as hard as rocks. Also, nerves come out of either the left or the right sides of the body. If a right-handed person experiences tension exclusively on their left neck and shoulder, there’s a chance that it’s not being caused by a behavioral habit like how they hold their smartphone, but rather, it might be resulting from a cranial nerve. ◆The Path from Young Train Enthusiast to Chiropractor Sugihara: Spoken by a true professional, ha ha. By the way, had you been aiming for this specific career path since your student days? Yamaguchi: No, not at all, ha ha! Back in my student days, I was completely obsessed with steam locomotives. I spent all my time traveling across Japan, from the wilderness of Hokkaido down to the southern tips of Kyushu, just to take photos of trains. I was a total fan of train photography. But since I had absolutely no money, I traveled on an incredibly grueling budget and schedule. I’d catch a train at midnight, scramble to make a transfer around 3:00 AM, and finally arrive at my destination around 6:00 AM. Combined with the return trip home, it was quite rough on my body. My family home was in Shinjuku, so I would frequently drop by the Kinokuniya bookstore to stand in the aisles, using books about stretching as references. Even after graduating from university, that habit of visiting Kinokuniya stuck with me. One day, while wandering through the orthopedics section, I found a book written by a chiropractor titled Improper Backbone Shape Triggers These Illnesses. When I picked up that book, I had no idea what was inside, but it became the very reason why I entered the chiropractic world. The book’s contents were absolutely fascinating to me. Until that moment, I had always assumed physical pain was exclusively caused by overdoing things or bumping into something. But this book claimed that poor posture alone could cause problems for all sorts of body parts. I found it so intriguing that I immediately called the phone number printed in the book, and they pointed me toward an institution where I could actually study chiropractic medicine. ◆Quitting a Job, Working Part-Time Every Night, and Studying until Morning Yamaguchi: I agonized over the decision for a few months, but I finally made up my mind, quit my corporate job, and worked part-time while studying. At the time, I worked at Potomac, a traditional-style coffee shop inside the Akasaka Prince Hotel. My shifts ran from 4:00 PM until 12:30 AM. Afterward, I’d get a ride back to my home in Waseda and keep studying until daybreak. However, that study schedule didn’t bother me in the slightest. Perhaps because my sympathetic nerves were stimulated from my part-time job, I was able to stay very focused deep into the night. Just like when I was studying for university entrance exams, my brain was operating at full power. Every single day, I would completely lose myself in anatomy textbooks until dawn. Just as it was becoming light outside and people were starting to walk around, I’d fall asleep. Then, I’d wake up in the afternoon, and head back to work again. Looking back, I sometimes wonder if my father’s experience as a combat medic treating wounded soldiers in the war got passed down to me through DNA or something. He wasn’t a military surgeon, but as a combat medic, he still treated countless individuals under extreme pressure. I am not a medical doctor either, but the fact that I have dedicated my life to preserving people’s health makes me feel connected to him somehow. Sugihara: How many years ago did you first become independent? Yamaguchi: My first time trying to go independent was about 40 years ago. I was naive, so I simply registered my home address as a chiropractic research institute and mailed advertisements to dozens of companies listed in the quarterly business journal. I remember pouring a drink and eagerly waiting by the phone to see how many responses I’d get…but of course, there weren’t any, ha ha. There were no personal computers back then, so I had simply typed a plain text document on a word processor. No diagrams, and no one whom I could use as a reference. It was just a letter stating, “I wish to help meet the health needs of your company’s employees.” However, when I shared what I was doing with my mentors and close friends from university, three of them actually went out of their way to negotiate with their respective employers. They managed to get permission for me to utilize their companies’ medical rooms and employee lounges once a week or twice a month. Instead of having to force my way in, I was able to build up my practice through those companies officially. Later on, I was contacted by a famous practitioner in Shibuya who recruited me into one of Japan’s top-tier chiropractic clinics. Their clients were prominent figures from various fields, including three former Prime Ministers, professional athletes, executive members of major businesses, major real estate companies, and the aviation industry, well-known celebrities, etc. Sugihara: And you call that your ‘training period’? Ha ha… Yamaguchi: Yes, that really was my training period before I went independent. At that clinic, some of the patients wouldn’t pay any attention to me, but when the director entered, they would smile happily and start a conversation. When I saw that, it ignited a fighting spirit inside me. After all, it was perfectly natural that none of them would be particularly interested in talking with a young kid, since they were coming to see the director, who they felt would keep their bodies in good health. At some point, I had the thought that I would become like him someday. ◆A Professional’s Perspective: Analyzing a Person through Walking Style, Facial Expression, and Tone of Voice Sugihara: In your line of work, dialogue must be a critical component of administering an effective treatment, right? Yamaguchi: It is absolutely necessary. Observing the way a patient walks through the door, their responsiveness when speaking, or any subtle deviations from their usual baseline is part of the treatment, not just the physical adjustment. Keep in mind that patients who are bordering on clinical depression, for example, present themselves with a rounded spine and a downward gaze the moment they enter. Even the person’s response to a greeting can signal that something is not right. I approach every treatment by holistically evaluating a person’s walk, sitting posture, facial expression, and voice. Sugihara: I resonate with that deeply. Back when I worked in business development, and even now when I interview entrepreneurs as an investor, it is exactly the same. Naturally, I ask structural questions about their business model, market domain, and technical solutions. However, what I am truly analyzing is the expression on their face when they walk into the room, the level of confidence radiating from their answers, and the way their eyes light up when you hit them with a poignant, spot-on question. My primary goal is to thoroughly evaluate the individual’s underlying OS. It’s the same sort of evaluation. Yamaguchi: I actually conducted a survey among students at Waseda University regarding their impressions of individuals with rounded backs. The overwhelming responses were descriptions like “lacks confidence”, “frail”, or “looks like life isn’t going well”. Furthermore, a slouched posture is a primary reason people look prematurely aged. Conversely, an upright, elongated spine not only projects youthfulness but physically lifts the muscles that control facial expression and optimizes blood flow to the brain. When posture collapses, cerebral blood flow stagnates, causing brain activity to decelerate. Correcting your alignment is truly a strategic investment that simultaneously optimizes both your internal state and your external presence. Sugihara: Absolutely, a slouch immediately projects a lack of confidence. I pay close attention to facial micro-expressions during interviews as well. Occasionally, someone will give off a distinct negative vibe or energy. No matter how eloquently they speak, it makes me pause and reconsider forming a deep partnership with them. Alternatively, when reconnecting with an entrepreneur after a while, even if they say, “I’m doing great,” I will cross-reference that statement against their posture, eye strength, and overall expression. If I sense an underlying misalignment, I gently prompt them to tell me if anything is wrong, and adjust how I interact with them if necessary. Yamaguchi: Facial expressions dictate your physical state, and your physical state dictates your facial expressions. This goes both ways. For example, when a patient’s stomach lining is inflamed, the distress often manifests as acute tension in the upper back. While I cannot physically massage someone’s internal organs, relieving the tension in the back muscles can indirectly soothe the stomach. The same principle applies to depression. By physically unburdening and loosening the spine, I can often alleviate some of the emotional weight clouding the mind. The body and the mind are profoundly and inextricably linked. ~To be continued in Part 3~ Interview conducted by D-POPS GROUP’s advisor Genta Sugihara.

[Founder Interview #6] Hiroshi Yamaguchi (Aoyama-Itchome Chiropractic Clinic) – Part 1
Before Your “Health Circuit Breaker” Trips: What Executives Need to Know About the Body’s Warning Signs and the Power of Posture For this installment, we interviewed Director Hiroshi Yamaguchi, a chiropractic professional with a career spanning nearly 40 years. After encountering one single book, Dr. Yamaguchi quit his job to pursue chiropractic medicine, studying while working part-time jobs in the evenings, and began working at a chiropractic clinic in 1987. Driven by a desire to practice a treatment philosophy aligned with his own values, he went independent and opened the Aoyama-Itchome Chiropractic Clinic, which has been operating to this day. He has treated a cumulative total of over 90,000 patients. As a director of the Japan Posture Education Association, he has taught courses at the Open University of Japan and appeared across various media platforms, serving as a prominent figure in the field for many years. We sat down with Director Yamaguchi to learn a professional’s perspective on why leaders ought to consider their bodies as an asset, which provided critical insights for building a Venture Ecosystem. (This interview was conducted in April 2026.) ◆What is a “Health Circuit Breaker”? — The Moment the Body Hits Its Limit Sugihara: One passage from the pre-interview report you shared with me left a deep impression on me. “For people who work incredibly hard, even if they aren’t sick, sometimes their physical health will very suddenly fail. I think of this as a “health circuit breaker” tripping. To use an electrical analogy, it’s like running your appliances right at maximum capacity, and the moment you turn on the microwave, the breaker trips.” I think a lot of people have seen this happen to themselves or their coworkers. Could you elaborate on the intent behind these words? Yamaguchi: When you are throwing yourself entirely into your work, you are usually aware that your body is tired. But if you aren’t experiencing actual pain, how do you react to that? Most people think, “If it doesn’t hurt, I must be fine. I can keep going.” This sort of “no pain means I’m fine” mindset is exactly what makes it easy for your health circuit breaker to trip all of a sudden. Even when the body is fatigued, even when joints are stiffening and muscles are swimming in lactic acid, it can still maintain high performance. This is because the body secretes “hustle hormones” like adrenaline to override the fatigue. Furthermore, the brain has a built-in filter that blocks out minor discomfort signals so they don’t disrupt our focus. In fact, if our brains didn’t do this, we wouldn’t be able to get any work done. To return to the electrical analogy, if an average person operates on a 30-amp capacity, an adrenaline-fueled executive’s capacity gets up to nearly 60 amps. Even while using a massive amount of electricity, the breaker doesn’t trip. However, because a person like that is running so close to the limit, the smallest, most trivial thing could suddenly blow the entire circuit. What I hope is that leaders will intervene before their bodies reach that point. ◆The Body Speaks in Tension and Stiffness, Not Words Yamaguchi: At the stage where you start thinking, “Am I using too much power?” like in the electrical example, tension and stiffness are the body’s signals. I want people to catch themselves at that exact stage and do something about it. Your body cannot communicate in words. Instead, it uses stiffness and tightness to tell you, “I’m exhausted”. For example, it can’t say, “If you stay seated for another 30 minutes, your lower back is going to seize up when you stand.” Instead, it gives you a heavy, dull ache while you sit. Your body gives you these kinds of signs. The thing that’s dangerous to do is to mask that discomfort with painkillers and keep pushing. There was a case where a patient repeatedly took medication to numb back pain and be able to keep playing golf, only for it to escalate into excruciating agony. The person finally went to the hospital, and learned it was a compression fracture. This is the equivalent of a small fire breaking out in your house, the smoke detector going off, and you disabling the alarm because it’s too noisy. If you ignore the warning, the entire house burns down. I am by no means anti-medication; it is absolutely necessary. However, using medicine solely to silence pain so you can continue working past your limits will result in damaging your body. Sugihara: I am sure this hits home with many of the executives and hard workers reading this right now. There must be a lot of people who experience a dull, lingering ache in their backs that they don’t think they could convey to a doctor even if they went to a clinic, but then the moment their stress levels drop, it vanishes naturally. At least, I know I myself experienced that during times when I had a lot of stress, ha ha. ◆What Diverse Leaders from Office Workers to Cruise Ship Captains Have in Common Sugihara: For our second question, from what professional backgrounds do Aoyama-Itchome Chiropractic Clinic’s patients come? Yamaguchi: The majority of my clients are everyday office workers and homemakers. However, I also treat a significant number of business executives and high-profile leaders. For instance, the captain of one of Japan’s largest luxury cruise ships is a regular patient. While a cruise ship’s route is predetermined, it is the captain’s responsibility to assess the waves and wind conditions in real time, deciding whether to steer slightly ahead or take a wide detour, and ensuring the passengers enjoy the safest, most comfortable voyage possible. In short, they are the ultimate decision-makers responsible for thousands of lives. Because of that heavy burden, they realize their own bodies must remain healthy. That is the mindset that brings them to my clinic. Sugihara: That’s a great point. To use a corporate analogy, the ship’s crew members are the employees, and the passengers are the customers receiving the service. The captain is the President or CEO. If the person at the top isn’t healthy, you simply cannot provide a safe, high-quality service. Yamaguchi: Precisely. Businesses are the same way. I also treat a woman who served as a top executive for a world-renowned theme park. She oversaw multiple massive divisions, including the theme parks, retail shops, music, and films, and she achieved incredible results. Even though she is highly dedicated to her own personal fitness training, she visits us regularly in order to keep up her physical condition. She once told a friend of hers, who was the CEO of a TV network, “The only reason I can perform this job properly is because I have a chiropractor looking after my body.” The role of chiropractors is to act as the behind-the-scenes supporters who help leaders to be able to succeed and smile, so hearing that was incredibly rewarding. Another long-time regular is a legendary broadcasting executive who led Japan’s massive transition from analog to digital television. The switch required replacing every single piece of broadcasting equipment and receiver in the country. He had to negotiate extensively with major electronics manufacturers, saying, “The networks are switching to these specifications, so you need to build products that match them.” For the manufacturers, making massive financial investments to build new factories in an uncertain climate was an immense risk. One of his subordinate directors later visited my clinic and admitted, “I could never have pulled off a negotiation that intense.” So, the fact that we enjoy seamless digital broadcasting today as a matter of course is entirely due to the grueling efforts of leaders like him. He came to us during a time when his body was under severe physical strain, and I am profoundly grateful I could be of some help. I urge everyone in your Venture Ecosystem, please take care of your bodies. Despite their demanding schedules, many of the executives who visit us make time for sports and hobbies—golf, tennis, mountain climbing, playing musical instruments, and so on. I like to ask them, “What do you do with your sports gear or instruments after you finish using them?” Almost all of them reply, “Of course, I clean and maintain them thoroughly before putting them away.” It certainly feels good to see your beloved tools looking nice and clean. Now, all I’m asking is for you to take just a fraction of the care and respect you show your gear, and direct it toward your own body. Strangely, many leaders meticulously maintain their equipment but leave their own bodies pushed to the absolute limit. If you keep stacking task after task onto an exhausted body and falling asleep without first winding down, fatigue will build up until it manifests as severe, debilitating symptoms. Even if it’s only for a brief moment in between tasks or after getting home, slowly stretching your joints and muscles will improve blood circulation and be beneficial to your health. ◆The Terrible Experience and Perception of Posture Both Shared by Executive Regulars Sugihara: You’ve shared several fascinating case studies of high-level leaders. Assuming their initial visit to your clinic was triggered by acute physical discomfort, do they typically continue to visit you on a regular basis? How do they end up there? Yamaguchi: Of course, I get many patients who only walk through my door after their circuit breaker has already been tripped. However, there are plenty of corporate executives who establish a routine of regular visits explicitly to prevent that breakdown from happening in the first place. The reason is simple: almost all veteran leaders have suffered some sort of terrible experience at least once in their past. They know from firsthand experience that if you wait until the system crashes to seek help, the pain is severe, it takes time, and it costs money as well. They have learned for themselves that regular maintenance ensures that symptoms remain mild or are prevented entirely. The more seasoned the executive, the better they understand the strategic value of regular checks and corrections. Unfortunately, they almost always have to go through a painful experience to learn that lesson initially. It is easy for people to respect conditions like bone fractures because the pathology is visible on an X-ray. Conversely, it’s much harder to keep in mind the compounding value of maintaining proper posture and proactively conditioning the body. People frequently interpret good posture as simply one type of hygiene, but actually, I want to tell people that keeping proper posture is an investment that leads to the success of what they’re doing now. Companies have a leader at the top, the directors, the employees, their families, clients, and shareholders. The physical vitality of that leader directly dictates the performance of the entire organization. Therefore, health is an investment towards realizing your corporate vision. ◆The Mechanics of Poor Posture: What Happens When We Stop Moving? Sugihara: Depending on the industry, leaders face vastly different physical environments. Some stand all day, while others are entirely sedentary. For executives, sitting in a boardroom for a five-hour marathon meeting is part of the job. What kind of negative mechanical impact does prolonged poor posture have on one’s physical health? Could you walk us through that specific mechanism? Yamaguchi: To put it basically, humans are animals. As the word suggests, we’re supposed to move. *Note: ‘animal’ in Japanese is dobutsu (動物), which literally translates to ‘moving thing’. When you sit for hours without moving, freezing your joints and leaving your muscles unengaged, your blood circulation stagnates. Blood is the transit system responsible for delivering oxygen and vital nutrients throughout the body while carrying away metabolic waste. What happens when that infrastructure stalls? Imagine forcing an employee to work from dawn until dusk while denying them meals and locking the restrooms. Anyone would collapse under those conditions. When you sit continuously and restrict your blood flow, that exact same systemic deprivation is occurring inside your tissues. Specifically, habits like crossing your legs or staring down at a low monitor compound this structural stress. The point I emphasize most heavily to patients is the layout of the environment where they spend the vast majority of their lives: the height of the chair, the height of the desk, the position of the monitor, and the ergonomics of the keyboard. This setup is critically important. Not just for five or ten minutes, you are locking your body into these positions for hours on end, so how it’s set up has an immeasurable impact on your body. Sugihara: I try to be mindful of it, but maintaining perfect posture over a long period feels incredibly difficult. Before I know it, my alignment slumps. Furthermore, modern business professionals can accomplish work via a smartphone, so is it definitely bad to have a posture that’s looking down? Yamaguchi: When you use a smartphone and tilt your head forward by 15, 20, or 30 degrees, the burden on your neck increases dramatically. It’s said that the posture typical of smartphone usage can be equivalent to placing roughly one-third of your entire body weight directly onto your neck and shoulders. The human head alone accounts for approximately 10% of your total body weight. Think of it like holding two 2-liter plastic water bottles. If you hold them tightly against your chest, it requires very little effort. But if you extend your arms straight out in front of you and try to hold those same bottles, the physical leverage multiplies the strain. Your muscles will give out in less than five minutes. That exact compounding fatigue is what accumulates in your upper back and shoulders every time you look down at a screen, triggering chronic shoulder stiffness, tension headaches, and an inevitable drop in mental concentration. The above illustration shows how much the tilt of one’s head impacts the strain on one’s neck. ~To be continued in Part 2~ Interview conducted by D-POPS GROUP’s advisor Genta Sugihara.

[Founder Interview #4] Tsuyoshi Tateishi (SpeakBUDDY) – Part 3
The Challenge for an AI English Conversation App: Creating a Language Acquisition Technology to Globalize Asia In this final part of our three-part series, we look back at the greatest crisis SpeakBUDDY faced in its 13-year history. President Tateishi shares how he navigated a dire situation, with only three months of runway left, by being brutally honest with his employees. We also discuss the company’s unique organizational culture, where a multinational team of over 10 nationalities balances autonomy with discipline, and explore his grand vision for leading Asia’s globalization. Finally, we reveal how their partnership with D-POPS GROUP is accelerating SpeakBUDDY’s ambition to become a unicorn company. (This interview was conducted in January 2026.) See Part 1 and Part 2 of the interview here. ◆Understanding How Long a Year Can Feel to an Entrepreneur Sugihara: It has been exactly 13 years since you founded your company. During that time, you’ve navigated various shifts, including the COVID-19 pandemic. Looking back over these 13 years, what were the major turning points or obstacles that you encountered, both personally and as a company? Tateishi: While the company was founded quite a while ago, for the first three years, I was developing non-AI English learning apps and operating solely on my own personal capital. The situation changed dramatically around 2016, when we pivoted fully to AI-driven English conversation and began receiving investment from venture capitalists. In that sense, it has been a long road. One thing that surprises you when you become an entrepreneur is that one year feels incredibly long. You’ve likely heard of Janet’s Law, which suggests that time feels like it passes faster as you get older. By my seventh year at the investment bank, my colleagues and I would often say, “This year is already almost over!” I think that happened because I had mastered most of my tasks, the work had become routine, and there were fewer new stimuli. However, when you start a business, new challenges appear one after another, day after day. Each time, you have to acquire new skills or come up with fresh solutions. This density of experience makes a single year feel exceptionally long. Doing that for over a decade has been a very lengthy, yet fascinating process. Regarding the COVID-19 pandemic, AI English conversation benefited a lot from the stay-at-home environment at first. However, as the period of restricted travel dragged on, Japanese people sadly stopped studying English. With no business trips, no international visitors coming to Japan, and no overseas vacations, their opportunities to think about English virtually disappeared. The entire English learning industry slumped, and it was a very difficult time for us. Fortunately, demand has now fully returned. ◆The Ultimate Crisis: An Honest Confession with 3 Months of Runway Left Sugihara: Of all the situations you’ve faced over the years, if you had to pick one, what was the biggest hurdle? And more importantly, how did you manage to overcome it? Tateishi: It was undoubtedly the period during the lead-up to our funding round, when our runway (the time left before we ran out of cash) was nearly gone. In a startup setting, you’re constantly accelerating hiring to fuel growth. When the pressure to raise capital hit at the same time as the need to keep the organization unified, it was incredibly intense. Developing AI services is a marathon. At first, the tech can’t quite match human performance, so you go through years of not being able to amount to much. But then, you hit a tipping point where the AI suddenly starts outperforming humans, and growth just takes off. 2019 was that turning point for us, and it was also our hardest year. We were right on the cusp of our Series A, but we only had about three months of cash left in the bank. I was running myself ragged trying to secure funding, while the team seemed—at least to my eyes—a bit too relaxed. Eventually, I couldn’t bear the stark contrast between my stress levels and their composure any longer. Until then, I had kept our financial numbers and cash flow concerns private because I didn’t want the team to worry, but I had finally hit my limit. I called everyone together and told them honestly, “This is exactly how much cash we have left, and this is how much we burn every month. If you do the math, we have three months. Our payday is the 25th, so I can pay you this month, but three months from today, I won’t be able to pay you any more.” I knew the risk that everyone might jump ship. But I couldn’t keep going with that emotional disconnect, so I decided to put all the cards on the table. While one person did choose to leave, the remaining ten members said, “Let’s find a way to push through this together,” and they really worked hard. That moment erased the inconsistency I had been feeling, and seeing them commit gave me the courage to keep going myself. First, I went to my former boss and humbly asked for a bridge loan to extend our runway by another three months. Then, during those three months, a new feature we developed became a massive hit. Our KPIs skyrocketed, and revenue went up as well. People started telling me, “Since you’ve come this far, I’ll throw in my investment.” We successfully raised about 300 million yen in our Series A. That was the most grueling time of my life. Since then, I’ve made it a point to share the details of our company’s expenses and exactly how much cash we have on hand. Sugihara: By doing that, I imagine the employees feel like they are truly in the same boat. Tateishi: Exactly. At the end of the day, you can’t reach the same decision if you don’t have the same information. I believe that if you make that information open to others, you’ll eventually reach a shared understanding. ◆A Team of 10+ Nationalities: The Strength and Struggle of True Diversity Sugihara: SpeakBUDDY is a remarkably global company. About a third of your employees are non-Japanese, representing over ten different countries. What are the benefits of this multinational team, and what challenges have you faced? Tateishi: It’s a bit of a chaotic mix, ha ha. ‘Diversity’ sounds great as a buzzword, but in reality, managing it is incredibly difficult. Everyone has different perspectives and values. It’s a constant challenge to keep everyone aligned. However, the upside is that it naturally brings in ideas we never would have had otherwise. We can flexibly adopt global best practices and viewpoints that aren’t bound by Japanese common sense. Plus, since we are a language company, many of our Japanese hires join specifically because they studied English and want to work in an international environment. For them, working in a cross-cultural team is a source of genuine professional fulfillment. From a management standpoint, it’s a huge strength. For specialized roles where the domestic talent pool is small, such as engineers and designers, widening our search to include global talent allows us to hire elite performers. Although, running all-hands meetings in both English and Japanese with simultaneous interpretation can be rough, ha ha. ◆Encountering D-POPS GROUP Sugihara: You recently attended our business briefing and social gathering. What were your impressions? (Click here to read more about the event.) Tateishi: I was primarily struck by the sheer number of people in attendance, since they were all executives! It made a deep impression to see leaders of that caliber listening so intently to our story, asking sharp questions, and offering collaboration ideas on the spot. During the formal briefing, I felt a bit of a distance, but once the drinks started flowing at the social gathering and we got into our personal stories, I felt like I was immediately accepted as a companion. I really felt that D-POPS GROUP is a company with a strong family vibe. Actually, we have a new feature currently in the R&D stage that hasn’t been released yet. When I shared the idea at the briefing, the reaction from the audience was overwhelming. Afterward, our Executive Officer Morimoto and I were talking about it, and we’re pretty sure that idea is going to be a hit. Having that kind of validation from a room full of entrepreneurs gave us the confidence that we’re heading in the right direction. Sugihara: SpeakBUDDY already has many supporters and investors. Why did you decide to accept our investment, and what has the experience been like so far? Tateishi: The biggest reason was that President Goto, and you as well, really listened to us with such sincerity. It made us really want to grow alongside you. D-POPS GROUP is a very unique organization, and there are many elements of your company that make me think, “This is the kind of company I want to build.” When we were raising the funds, I told my team, “I want entrepreneurs whom I truly respect to become our shareholders. I want us to aim to become a company like D-POPS GROUP, so I absolutely want to accept their investment.” My thoughts at the time were, “I want us to learn from you, so please invest in us!” ◆Building a Great Company that Balances Autonomy and Discipline Sugihara: Regarding our company’s aim of realizing a Venture Ecosystem, are there any parts of that vision that resonate with you? Tateishi: Above all, I deeply resonate with your commitment to developing unicorns. To be honest, I’ve never been the type of person to put stickers on my laptop, since I always felt, “I don’t want to ruin a machine that I’m trying to keep clean!” However, since the D-POPS GROUP unicorn sticker has a genuinely cool design, and more importantly, it serves as a constant reminder of your ambition for us to reach unicorn status, I decided to put that sticker on my laptop. Sugihara: We really appreciate that, especially since you don’t even put your own company’s stickers on it, ha ha! Now, where do you see SpeakBUDDY in 5 to 10 years? Tateishi: Over the next five years, our vision is “to become the AI language acquisition startup driving Asia’s globalization”. And in ten years, we want to fully realize our mission: “Open a world of opportunities by achieving true language acquisition.” Lately, one thing I’ve been consciously trying to pursue is “to build a truly great company”. This may be an abstract goal, but I want SpeakBUDDY’s very existence to make people say, “I’m glad this company exists.” To achieve that, I feel like we really need to return to the roots of our mission, vision, and values. Organizationally, we spent the last year significantly strengthening our discipline. Startups are often free-spirited, autonomous environments, and we ourselves operate on a hybrid model centered on full-remote work. I’m personally someone who didn’t originally like to create rules, but as we grew past 60 employees, errors and accidents inevitably started to occur. So, I decided to steer us toward a culture that strongly asks for discipline and accountability. I recently read that “only by balancing autonomy and discipline can one create a great company”, and it struck a chord. Autonomy without discipline is chaos, but discipline without autonomy is stagnation. I want both at a high level. Sugihara: Autonomy and discipline seem like opposites, but they are actually two sides of the same coin. At companies like Google, the environment looks free, but the governance and the focus on achieving goals are incredibly intense. You are free to choose how you work, but you are also held totally responsible for the mission. Both aspects co-exist. Tateishi: Very true. That’s directly related to the recent moving of our office and us paying closer attention to the culture we’re building. ◆From Asia to the World: Leading Global Integration Sugihara: Do you have concrete plans or an outlook for expanding into the market in Asia and the rest of the world? Tateishi: We do. While we’ve temporarily paused our efforts to enter the Taiwanese market, we’re looking at opportunities to move into East Asia first, followed by Southeast Asia. Ultimately, we want to expand to Europe and the rest of the world. Sugihara: Right, since Southeast Asia alone has a population of over 600 million. Tateishi: It is a remarkably attractive market. There are billions of people worldwide struggling with English, so we want to provide our services to them, for sure. First, we’ll focus on succeeding in Japan, and then scale up from there. ◆A Message to Readers: “A New Way to Master English” Sugihara: Finally, do you have a message for our readers? This column is read closely by executives, entrepreneurs, and investors who have a real eye for professionalism. Tateishi: Everyone can feel the staggering pace of AI evolution every day. In an era like this, I believe we are being asked to question traditional methods and try something new. For English learning, too, I encourage everyone to try different methods from what you’ve done before. At the risk of sounding biased, I believe English is only going to become even more important for business professionals as AI makes international collaboration easier. We are seeing an increasing number of young people for whom English fluency is a given. We hope the professionals currently leading our industries will also take advantage of SpeakBuddy to brush up on their language skills, develop their own unique English style, and not get left behind by the younger generation.
