Interview with Tatsumasa Hosaka: a Daring Voyage Toward Realizing a “Venture Ecosystem”

At D-POPS GROUP, we have 23 group companies as partners (at the time of publication).
On this occasion, D-POPS GROUP Advisor Genta Sugihara interviewed President Tatsumasa Hosaka, who founded STAR CAREER CO., LTD in 2016.

◆Background of STAR CAREER’s Establishment

Sugihara:
Today we’re interviewing President Hosaka of STAR CAREER. Thank you for your time. First, could you tell us about how you came to be the president of STAR CAREER?

Hosaka:
Sure! STAR CAREER was founded in 2016.

I joined D-POPS in 2006 and worked as a store manager and division director. Actually, starting around 2014-2015, President Goto, who founded D-POPS and currently serves as President and CEO of D-POPS GROUP, was offering an entrepreneur training school of sorts (which has become affectionately known as “Goto School”), and there were some members of the D-POPS stores who also participated.

Mr. Fujita, who is now the chairman of the board at Advancer (one of the group companies), was the first in-house entrepreneur to win an MVP award at Goto School.

Actually, I never attended Goto School myself, instead putting myself in a position to support other members within D-POPS who wanted to become entrepreneurs or create new companies within the group.

One day, President Goto approached me after D-POPS achieved 10 billion yen in sales. As we began setting our next goals for 30 billion yen, 50 billion yen, and 100 billion yen, he had come up with the idea of starting a new company within the group, one specifically related to human resources. When he shared the plan with me, I immediately started to recommend other members, saying things like “How about this guy?” or “How about that guy?”

Then President Goto asked me, “Hosaka, why aren’t you putting your own hat in the ring?”
I replied, “Well, I guess I'd rather focus all my energy on leading the younger D-POPS members to help us reach 30 billion and 50 billion yen!”

That evening, when I was having drinks with my junior D-POPS colleagues (which was a regular occurrence), I told them about my conversation with President Goto and how I had declined because I wanted to achieve the 30 billion and 50 billion yen goals together with everyone.
They responded, “What are you talking about?! You go do it! Leave this to us and show us how it’s done!”
Realizing they were right, the next day I went back to President Goto and said, “Remember what we were talking about yesterday? Please let me do it.” That’s how it all started.

Sugihara:
Was your experience at D-POPS useful in managing your own company?

Hosaka:
It was, and still is. Back then, stores operated on an independent profit system. They managed their own sales and gross profits, and independently funded campaigns using the store’s personnel budget. In a sense, it was effectively like running their own small-scale businesses.

So, depending on the store manager, a store could either become very profitable or fall into the red. We weren’t focused solely on sales numbers or the volume of contracts—each store was essentially running its own business. This experience of running a mini business at the store level has been extremely valuable for my current management role.

Sugihara:
Being able to learn management at the store level must have been very educational. By the way, at that point, how many companies were in the group besides D-POPS?

Hosaka:
At that time, there were only Good Crew and Advancer.

Sugihara:
I see. So then, you were starting the group’s third HR-related company?

Hosaka:
Actually, Advancer wasn’t an HR company at the time…it was a secondhand shop for smartphones. They later pivoted to become the HR company they are today.

Sugihara:
Oh, I didn’t know that! Well, what were the differences between Good Crew and STAR CAREER back then?

Hosaka:
There were two main differences. First of all, STAR CAREER wasn’t just focused on mobile businesses—in anticipation of the Tokyo 2020 Olympics, we launched with the concept of providing specialized staffing for customer service and store operations in brick-and-mortar businesses like hotels and restaurants.

Second, at that time, Good Crew was struggling with recruitment, hiring only 30-40 people annually. We accepted the mission that President Goto proposed: “Hosaka, let’s aim to hire 100 people.” As a result, STAR CAREER ended up hiring 107 new graduates that April.

Interestingly, the following year, Good Crew managed to hire 100 people as well. I think this was part of President Goto’s strategy to foster growth through competition.

Starting recruitment activities right after founding the company and hiring 107 new graduates was challenging enough, but then around November, President Goto said, “There’s a company joining through M&A next April. I was thinking you could manage that one, too.”
Since we had just started this brand new company with only two people including myself, I was asking myself, “Really??”, while in the same breath, I answered, “I’ll do it!” And so, with that, I also became the manager of graphD.

Sugihara:
That sure escalated quickly! You seem to be the type who can handle—or at least be willing to handle—any obstacle that comes your way.

Hosaka:
I love getting thrown curveballs! I want people to think of me as “that handy guy”.

Sugihara:
That’s really important, isn’t it? From the perspective of top management, having “handy people” among executives is absolutely essential, and those individuals end up getting more and more work thrown their way. The more work they’re given, the more they develop and gain experience. It’s a beneficial situation for executives, but something similar can be seen in group company management as well. Even as a CEO running one organization, to be seen as a “handy guy” by the group’s president must be important, or rather, desirable.

Hosaka:
Yes, I was quite happy about that! But then, I was also thinking “Seriously?!” about establishing a new company in April when 107 new graduates were also joining at that same time, ha ha.

◆STAR CAREER’s Business

Sugihara:
Could you briefly introduce us to STAR CAREER’s business model?

Hosaka:
As of 2024, we’re a comprehensive HR services company that operates job hunting cafes which we call Career Work Cafe. With these job hunting cafes at our center, we run three main businesses: temporary staffing, job placement, and recruitment outsourcing.

Sugihara:
I see. So those job hunting cafes are the core of your business.

Hosaka:
That’s right. When companies recruit, they typically either post on platforms like MyNavi and wait for applications, or work with recruitment agencies to find candidates. From a job-seeking student’s perspective, our job hunting cafes serve as a platform that’s neither a job board nor a recruitment agency…it’s a unique place they can reach out to.

Sugihara:
How do job-seeking students learn about your job hunting cafes?

Hosaka:
Basically, we have partnership agreements with student organizations. For example, we work with student groups supporting refugees in Laos and Cambodia, or those who help at dog and cat rescue centers. We open our job hunting cafes as meeting spaces for them and provide them with a place for their activities. We also regularly sponsor their activities with contributions of around 50,000 or 100,000 yen each.

In exchange, students registered with these organizations come to our job hunting cafes when we hold events or information sessions.

Sugihara:
So, since your core business is supporting job-seeking students with these job hunting cafes, you mainly handle recruitment and placement of students. I imagine many of your own hires are students and young people…how do you handle their education and training?

Hosaka:
First of all, we do training for those who’ve received tentative job offers and for new hires. Then, we do group training sessions every month for a full year after that.

While many other group companies and external staffing agencies do similar things, our temporary staff work one day less at their placement sites compared to other companies. In a sense, we’re using that day for training, so they spend less time at their placement sites.

What we consistently tell our members, from the time we tentatively offer the job until they are hired, is that “When it comes to work, in order to do what you want to do, focus on increasing your skills, and you’ll eventually be able to do what you want.”

Now, when it comes to level and skills, most people seek to acquire skills, such as earning certifications or studying abroad. Skills are indeed powerful assets, of course, but it’s like in Dragon Quest: even if a character has a level 50 weapon (skill), it can’t be used effectively if the character itself is only level 1. In the same way, without raising your own level, you can’t utilize those skills. So rather than just improving skills to increase a member’s market value, we focus on raising the member’s level for the first year.

We encourage our members to go from level 10 to 20 to 30, while also honing their skills at the same time. Instead of just telling people to work in stores, we offer monthly training sessions to teach them how to face challenges they might encounter in those stores, how to approach problems mentally, how to seek cooperation from others, and how improving your level enables you to handle work better.

Sugihara:
That’s wonderful. What you gain from leveling up is much more valuable than focusing on skills like certifications first. Not that certifications are useless, but in terms of English, for example, it’s better to become a business person who masters English through practical use and work experience, and then maybe takes a test and sees an improved score, rather than someone who can’t communicate in English but has a TOEIC score of 990. The former builds confidence and is definitely more valuable.

◆Challenges During the COVID-19 Pandemic

Sugihara:
Now for the next question. You’ve been managing this HR company for 8 years…how is your business doing recently? How was the company’s situation during the COVID-19 pandemic three years ago?

Hosaka:
During the pandemic, we suffered damage severe enough to shake our company’s direction. We had originally planned to focus on store businesses, providing staffing for hotels and restaurants, but then the Olympics were cancelled...

Originally, each color of the stars in STAR CAREER’s logo had a specific meaning. We started with the concept of specialized staffing for customer service in five areas: hotels, bridal, apparel, restaurants, and mobile phone shops. But when COVID made these business prospects uncertain, we had to remove all mention of them from our website and other materials. At the same time, we launched job hunting cafes as our business.

The long COVID era brought major changes to people’s lifestyles and perspectives, especially for the job-hunting students with whom we frequently interact. They started their freshman year right when COVID-19 began to interrupt life in Japan, and were seniors when the Japanese government reclassified COVID-19 from a Category 2 pandemic to a Category 5 (lower-risk) endemic disease. So, it makes perfect sense that they struggle to answer interview questions such as “What did you accomplish during your college years?”.

The job hunting cafe business, which started alongside COVID, transformed into something that aimed to expand people’s career options and make their life choices more colorful. However, when we first launched the cafes, we did lose some employees who had joined expecting to work in hotels and restaurants, saying “This isn’t what I was first told! I joined because of what was promised initially, but now we’re not doing that anymore.”

While maintaining our core principle of “connecting people with people”, we expanded into remote call centers and work-from-home customer support, areas that grew significantly during COVID. As the pandemic subsided, we also moved into in-office administrative work. Now, beyond providing environments for our members’ growth, we’ve strengthened our focus on offering various working styles to suit different life plans.

What COVID helped us realize was that whether it’s B2C or B2B, it’s ultimately about human connections. For example, when customers come to a store, they do so because they think, “Maybe this person can do something for me.” In B2B as well, since there are people involved, “This is a tight deadline…but maybe if I ask So-and-so, they’ll do their best to help.” In the end, work is all about people connecting with people.

Members who joined as new graduates saying “I’ll work super hard!” have now returned from maternity and childcare leave. Some continue to work just as hard, while others want a better work-life balance, and some want to work but can only do so under certain conditions. And I believe all of these choices are valid. Whether some members want to increase their income, enrich their private lives, or prioritize their family—when these various needs arise, we want to create options within the company to accommodate them, making it a place where people can work with peace of mind for a long time. I think the idea of making one’s life more colorful is the new meaning and intent behind our logo’s design.

As for business performance, our top line did temporarily decrease due to the changes in our business model resulting from the pandemic, but since then, our operating profit has actually increased!

Sugihara:
That’s wonderful. You went through a difficult period but came out stronger for it, and now you’re gradually shifting to a more robust business model.

Hosaka:
Yes. Now we dispatch more people to call centers and back offices than to mobile phone shops, so I guess you could say our group’s risk portfolio has expanded.

[Entrepreneur Interview #18] Fuminori Akamatsu (opzt) – Part 2
Life-Changing Experiences and a Valued Organizational Structure: opzt’s Future in Developing Trust In this final installment of a two-part interview, we asked President Akamatsu about his experiences as a musician, what made him decide to be an entrepreneur, his dedication to organization building, the entertainment business he launched after a serious illness, the background of the M&A with D-POPS GROUP, his resonance with realizing a Venture Ecosystem, his vision for five years from now, and a message for our readers. (This interview was conducted in August 2026.) This is the latter part of the interview. To read the first part, click the link below.https://d-pops-group.co.jp/en/column/opzt-interview-first-part/ ◆Applying Experiences from His Band Member Days to Business Management Sugihara:Let’s step away from the business topics for a bit and talk more about you. I’ve heard you used to be a musician. Is that true? Akamatsu:Yes, it is true. I played the bass when I was younger and lived in a world completely different from corporate management. However, in a band, if only one person is skilled, the team doesn’t come together. I think there are actually quite a few similarities with managing a company. Everyone has their own personality and abilities. But in the sense of trying to build a single stage on which to perform, I feel corporate management is much the same. Sugihara:So you cultivated a sense of teamwork and balance over a long period in the field of music. Has your experience as a musician back then helped you in your role as CEO? Akamatsu:I suppose so, though it’s hard to say for sure. The sense of reading the audience’s reactions during a live performance and grasping what they want might be something I still utilize today. Sugihara:That makes sense. You definitely can’t do business with major corporations if you can’t read the room. ◆Creating a Company to Be Proud Of: The Background of opzt’s Founding Sugihara:You touched on this briefly earlier, but could you tell us again: what was the catalyst for starting opzt, and how do you feel now looking back on the 13 years since founding it? Akamatsu:My original motivation for starting a business wasn’t a grand plan to build a massive corporation. Rather, it was a somewhat modest ambition to run a business I alone was responsible for, and create a company that my employees and I could truly be proud of and satisfied with. I didn’t have some sort of grand vision. About 20 years ago, the HR industry was full of extremely exploitative, so-called “black companies”. While working in that environment, part of me felt a desire bubbling up to build a company that would value workers more and could respond more quickly and flexibly to clients. That was how I decided to start up opzt in 2013. Looking back over these 13 years, more than the company’s sales or scale, my strongest feeling is that we’ve somehow made it this far thanks to the connections and relationships we’ve built with people. Sugihara:It’s wonderful that your journey began not with a grand corporate scheme—which doesn’t always go well for entrepreneurs without a concrete plan—but from a genuine desire to provide everyone with an ideal workplace due to your personal experience. In my case, I joined my previous systems company intending to be an engineer, but as it turned out, it used to be a dispatch business back then. My boss would only show his face about once every six months, and I was constantly working at a client’s factory. In those days, we were just seen as unit prices. Even if I was highly evaluated on-site, it was never reflected in my salary at all. That was the era, wasn’t it? In the end, I quit three years later, ha ha. Akamatsu:That’s exactly how it was. In those times, dispatch staff weren’t allowed to take paid leave, and if we were short on people, we were told to go recruit strangers on the street. We were judged solely on numbers and told to push for more overtime. It really was an unreasonable era. Sugihara:Speaking of that, I get the impression that employees who joined around the time of your founding have stayed with you for a long time. Is there anything you prioritize or keep in mind regarding your people in terms of organization building and company management? Akamatsu:Honestly, I simply have nothing but gratitude towards them. I am truly thankful that many employees have stayed for so long. What I value is not looking at employees merely from the perspective of job titles or numbers. Everyone has things they are good at and things they struggle with; some excel at sales, while others are great at administration. Rather than forcing everyone into the same mold, I consciously try to create roles where each person can thrive. Also, rather than having only the founding members make decisions, I want to properly provide opportunities to newer employees and nurture the next generation of leaders and managers. While we’re intentionally preserving those values, at the same time we are trying to transition into an organization that operates according to systems rather than relying on specific individuals. ◆A Philosophy of Helping to Raise Up Executives Instead of Micromanaging Individual Branches Sugihara:I often meet with the team members of opzt’s Tokyo branch based in Shibuya Hikarie. Even when you aren’t there, they work incredibly earnestly and harmoniously. They maintain a bright, positive atmosphere, mixing seriousness with jokes as they manage their tasks. With offices scattered across Nagoya, Shikoku, and Kyushu, as you mentioned earlier, how do your staff and employees work so independently and reliably? Akamatsu:Well, the key is actually to not micromanage each branch. The clients and recruitment markets are completely different depending on the region, and we’ve learned in the past that simply forcing them to use the patterns that are successful at our headquarters doesn’t work. And I think a major reason the Tokyo team can operate autonomously is that the local members think for themselves, make decisions, and commit to the results. It feels less like managing a branch and more like helping branch managers to grow. Sugihara:That’s impressive. Everyone truly acts with a mindset like they’re also an executive, and seem driven to boost Tokyo’s performance. ◆Lessons from a Serious Illness: The Background Behind the Birth of the Entertainment Business “SELEBRO” Sugihara:On a different note, I understand you run an entertainment-related business separate from opzt, called “SELEBRO”. You launched this company after opzt, correct? Akamatsu:Yes, that’s right. Currently, through SELEBRO, we operate live music venues and nightclubs, manage artists, and do event planning for music festivals, etc. As for our business model, we are also heavily involved in entertainment tech, a blending of entertainment and technology. It’s separate from opzt, and while its headquarters is also in Osaka, they aren’t here in this building. My love for music and entertainment was one of my original reasons for founding it, but the biggest factor was being hospitalized for a condition called cerebral artery dissection. It happened around June or July of 2019, about six months after we joined D-POPS GROUP in December 2018. It was completely sudden; when I went to the hospital, I was told to be admitted immediately. It was a truly desperate situation, and I spent a month in a state where every day could have been my last. That experience profoundly changed my outlook on life by 180 degrees. Before that, I assumed I still had a long future ahead and I would live until I was 80 or 90. That baseless assumption was turned upside down. I had vaguely thought it would be nice to try my hand at the music business at some point in my long life, but after going through that hospitalization, I realized that rather than thinking I’ll just do it someday, it was better for me to be intentional about doing it so I wouldn’t die with regrets. When I put on that mindset, old connections of mine from the music world started getting back in contact with me, fantastic venues opened up, and opportunities like that kept coming to me. I figured now I had to do it. So I spoke properly with President Goto, telling him, “This is what I want to do.” He told me as long as I continued to run opzt properly, he was fine with it, making it clear he didn’t want me to do either half-heartedly. By the way, I recovered from my medical condition. Eventually, my body was able to heal without surgery, and I’m in good health now. I feel like I’m getting a second chance at life. I no longer postpone what I want to do until “someday”, because you never know when you’re going to die. ◆Respecting Our Company’s Individuality: Why We Chose D-POPS GROUP Sugihara:Thank you for telling us so much about your personal life. You really went through a difficult experience. Now, you joined D-POPS GROUP in 2018 through an M&A. Could you tell us about that process and why you chose D-POPS GROUP out of the many offers you likely received? Akamatsu:At the time, my company was in its fifth year and approaching a scale of about 1 billion yen. As we grew to a certain size, I started to realize that to proceed to the next phase, we needed management resources and expertise that we couldn’t get on our own. That was the starting point. Since we were growing steadily, we were receiving offers from various companies. The reason I chose D-POPS GROUP was that I was drawn to your CEO’s personality and your philosophies. You didn’t want to simply acquire a company; you wanted to grow together while firmly preserving my identity as a manager and my company’s individuality. I have many peers who have gone through M&As, and I’ve seen numerous cases where the management policy changes after joining a group, or the founding manager leaves the business. In contrast, D-POPS GROUP continues to let me run the company, allowing opzt to grow while respecting our culture and strengths. I really appreciate how they gently watch over us. I really decided not based on terms or conditions, but based on who would be managing the company alongside me and whether my employees could continue working positively after joining D-POPS GROUP. Sugihara:Just as you hoped back then, your 1-billion-yen company has kept growing over these past six years. Have you learned a lot from President Goto and D-POPS GROUP’s management study sessions while keeping your own structure intact? Akamatsu:Yes. Every day, I get to learn more about various aspects, I’m still receiving mentorship, and I feel like I am studying on a daily basis. ◆More and More Managers Emerging from the Group: Resonating with the Venture Ecosystem Sugihara:That’s wonderful. Finally, D-POPS GROUP has the slogan of “realizing a Venture Ecosystem”. Please tell us what aspects of this goal resonate with you, and if you’re doing anything to help build this Ecosystem. Akamatsu:I resonate with a lot of aspects, but most of all, with the philosophy that it’s not just about one company succeeding, but about new managers and new businesses emerging one after another from within the group. As a founding manager myself, my goal isn’t solely to make my company bigger. I want to create a cyclical environment where the next business leaders and managers emerge from among our employees, and they in turn create new companies and businesses. Even within opzt, we give each branch authority and discretion, having them run the branches with the mindset of managing a small company. I believe that circulating the talent, funds, and trust generated by those operations into the next business connects directly to realizing a Venture Ecosystem, so I also agree with that idea. Sugihara:It sounds like you are creating an ecosystem within opzt itself, too. Akamatsu:Yes. The scale is still small, but I think they share common elements. ◆Five Years from Now: A Company Supporting Corporate Growth with People and Technology Sugihara:Please tell us what opzt will look like in five years, or any specific goals you have. Akamatsu:In five years, as I mentioned earlier, I want us to be a company that doesn’t just dispatch talent, but supports corporate growth by combining people and technology. Our staffing business remains a major foundation, so while we will firmly maintain that, I want to increase our focus on AI, data, and the data center sectors, transforming into a highly specialized and profitable business structure. Beyond that, I want us to be a company where employees and staff can properly grow, where clients need us for a long time, and where we generate appropriate profits to invest in new businesses. ◆A Message to Our Readers Sugihara:Lastly, could you share a few words with our readers? Anything is fine. Akamatsu:opzt itself is still an immature company, and I believe technology, including AI, will continue to change at an incredible speed. However, as a company, we want to challenge ourselves with new things without being bound by past successes. If anyone looking for a job happens to read this article, I hope you won’t limit your potential based solely on your current experience. Even if you lack experience now, you can build a new career by learning and taking on challenges. To any corporations reading this, we want to be a partner who can think alongside you, not just in introducing talent, but also in organization building, operational improvement, and taking on new business ventures. If you have even the slightest interest, please feel free to reach out to us. Sugihara:Wonderful. Thank you very much! Interview conducted by D-POPS GROUP’s advisor Genta Sugihara. opzt, Inc.

[Entrepreneur Interview #18] Fuminori Akamatsu (opzt) – Part 1
Building Trust with Major Corporations and Creating a Staffing Business that Develops Human Resources In this first installment of a two-part interview, we asked Fuminori Akamatsu, opzt, Inc.’s founder and CEO, about their business operations, how they build trust with major corporations, their expansion into the technology sector, human resource development, and their approach to the generative AI era. (This interview was conducted in August 2026.) ◆Introducing a Nationwide Business with 5 Locations, Centered on HR and Technology Sugihara: Currently, 26 group companies belong to D-POPS GROUP. Today, we are interviewing Mr. Fuminori Akamatsu, president of opzt, Inc., which joined the group in 2018. Thank you for your time! First of all, although it is posted on your website (available in Japanese only), could you give us an overview of your business in your own words? Akamatsu: Our core operations are centered around two main pillars: our HR business, which includes staffing, recruitment, and outsourcing; and our tech business, which handles the IT technology sector. Since our founding, we have provided HR services primarily for the telecommunications industry, focusing on administrative roles, call centers, and sales and promotional support. We currently operate out of five locations—Osaka, Tokyo, Nagoya, Shikoku, and Fukuoka—with many team members working throughout Japan. Recently, we have been focusing not only on conventional HR services but also on the IT technology sector, rolling out highly specialized HR services for roles such as AI specialists, data scientists, and infrastructure engineers. Currently, we mainly provide System Engineering Services (SES) and operate on an outsourcing and contracting basis, but in the future, we hope to develop and release our own in-house products. Sugihara: By the way, could you tell us the origin of your company name? Akamatsu: It originally came from the desire for our company to be our clients’ first choice. However, the word “choice” itself implies picking from a variety of options, whereas “opt” carries the nuance of proactively selecting something, so we embedded our desire to become that kind of company into the name. Since there was already a famous company called Opt, we wanted to avoid using the same spelling. We added ‘z’, the last letter of the alphabet, to make a new word which we gave the meaning of “the ultimate, best company”. Sugihara: So you drew inspiration from English and coined a new word to make your company’s name. About how many employees do you have in terms of the scale of your staffing? Akamatsu: Including both our headquarters staff as well as all of our dispatch employees, there are currently about 550 people registered with our company. ◆Building Trust from Year Two: Forging Bonds with NTT Sugihara: You have a very large pool of talent. How do you go about connecting with the clients where you dispatch your employees? I’ve heard before that you have many clients related to NTT. How did you manage to get your company involved with such a massive corporation? Akamatsu: A major factor is that when I was working as a corporate employee, I was given a lot of responsibility within NTT Group. Even though I was really just a young kid at the time, various key figures took me under their wing, allowing me to build not only business relationships but also deep interpersonal trust. Later, when I decided to start my own business, an NTT executive who had been a great mentor to me said, “If you’re going independent, I want to support you,” and offered to help me as an advisor. While that’s not the only reason, when I launched my business, former colleagues and other excellent individuals within NTT helped me out in various capacities. Because many of these individuals had long-standing trust, networks, and lots of personal connections with major companies like NTT, leveraging those connections to establish business deals became our starting point. And then, truly miraculously, we were able to sign a contract with NTT at the very early stage of our second year in business. Given that we didn’t have a Teikoku Databank rating at the time and weren’t yet the kind of company that they would typically even look at, I think our dealing with NTT was quite the exception. Sugihara: I believe your clients include other major corporations besides NTT. Many startups struggle to establish working relationships, so how did you and your management team pave the way for that? Akamatsu: We were truly fortunate to do business with a massive company like NTT in our second year, as it allowed us to learn through trial and error the difficulties of working with large corporations (things like information management, compliance, and talent quality). Because we were able to build a certain level of trust with NTT and establish an organizational framework for engaging with major companies, we were able to apply that to other large corporations, which helped us to get up and running relatively quickly. As has been the case for a while, rather than sales strategies that simply win contracts, we value strategies that focus on how long we can sustain those contracts. I believe our ongoing transactions with major companies like NTT and Docomo are the result of gradually building things up, one step at a time. Sugihara: What do you specifically pay attention to in order to maintain business with major corporations, or what do you think is the reason you enjoy such favor with your mentors? Akamatsu: I truly believe it’s the accumulation of consistently keeping small promises. It’s about trust—ensuring that the quality of our talent, compliance, and information management are solid, as I mentioned earlier. When a problem occurs on-site, we don’t hide it; we report it immediately and communicate how we will improve as a company. The larger the company, the more they scrutinize these aspects. So, we immediately and thoroughly address each issue. Our employees also strictly adhere to this principle, and I think the accumulation of all these efforts is what makes us stand out. We started from nothing, and while our initial entry point may have been personal connections, I don’t believe business relationships last this long purely on personal ties. It’s all about the cumulative effort. ◆From Routine Tasks to Highly Specialized Fields: Differentiating Their Business in the Era of AI Sugihara: I have the impression that your services have pivoted over these past 13 years. In particular, you recently started a tech-related staffing business. How are you differentiating yourselves in that area? Akamatsu: We didn’t originally set out with a conscious decision to pivot. Rather, as we kept our eyes on the HR market, we realized that routine and standardized tasks would inevitably become automated by AI. At the same time, we saw market movement showing an increased demand for talent capable of utilizing AI, such as data scientists and professionals in the AI and data fields. Our company realized about three or four years ago that if we just continued our traditional HR services, we would definitely be weeded out, so we knew we had to focus on high-growth sectors. However, we felt there was no point in doing the same thing as conventional SES companies. Therefore, we are specifically focusing on areas that directly tie into a company’s competitiveness moving forward, such as AI and data engineers, data scientists, and talent within the infrastructure field who can support data centers. Additionally, rather than only hiring individuals who already possess high skills, we are running a parallel initiative where we hire high-potential individuals with no prior experience, educate them, and develop them into specialized professionals while they gain practical experience. I believe combining the know-how we’ve cultivated in the staffing industry with specialized expertise in the technology sector is our unique point of differentiation that other companies don’t have. Sugihara: Your focus on the data center field, as you just mentioned, is definitely the right move. I’ve seen news from the US where, despite an increase in IT engineer layoffs, the demand for electricians is surging, to the point where even certified public accountants are quitting to become electricians or plumbers. I simply thought it was about having a tangible trade, but it turns out these jobs are related to data center construction. I hear there is a severe labor shortage, and while Japanese manufacturers are profiting from semiconductors and servers, there's also an ultimate demand for the people who actually install them. Akamatsu: That’s exactly right. In Osaka, in particular, data centers are rapidly increasing as backups for ones running in Tokyo. They are currently being built at a rapid pace with the idea that even if Tokyo falls, data can be protected in Osaka. Because these facilities require 24-hour monitoring and are often located in remote areas, telecommunications carriers are constantly struggling with labor shortages. We decided we wanted to tackle this head-on and are putting significant effort into it. I may use AI quite a bit myself, but people really are starting to use AI more and more. ◆Hiring Strategies and Educational Programs to Become Clients’ First Choice Sugihara: Now, I’d like to ask about acquiring the talent you actually dispatch to the clients receiving these services. I’ve heard of companies even within our own group that are struggling with recruitment. With costs rising and a shrinking talent pool to begin with, how is opzt tackling this? Akamatsu: Not to say it’s going perfectly well for us either, but we make a point not to rely on just one recruitment method. Our defining characteristic is that we use a mix of multiple recruitment channels—job boards, recruitment agencies, referrals, social media, and hiring events—depending on the job role and region. More important than that is becoming a company that applicants actively choose. Today’s job seekers look closely not only at the salary and job description, but also at what kind of experiences they will gain after joining, how it will lead to their future career, and how the company will treat them. Because of this, we make sure not to just say the good things, but to honestly explain everything: the job content, workplace environment, and expected roles. We place more emphasis on ensuring that the people who join us can thrive and work with us for a long time, rather than just focusing on the sheer number of hires. Sugihara: That’s wonderful. You mentioned that when people join opzt, you don’t necessarily just hire those who already possess high skills, but you also have programs to educate your employees. Could you elaborate on that? Can someone with no background in technology really become the kind of talent dispatched to that sector? Akamatsu: As part of our fundamental training, in addition to basic education on business etiquette, information security, and compliance, we conduct training tailored to each assignment. Especially in the tech sector, we don’t just have them learn online; we prioritize getting them to a point where they can use what they’ve learned in actual practice. We do this by creating assignments for them to present, supporting their acquisition of certifications, and pairing this with follow-up support from senior engineers. Furthermore, we believe that the ability to report, communicate, ask for help, and to understand a client’s intent is just as crucial as technical skill. So, we adjust our programs for each individual to cover these areas as well. Our goal is to develop talent that makes clients say, “I want to request this person for the job again.” ◆The Era of AI Agents: Stormy Seas or Smooth Sailing? Sugihara: Now, for this kind of staffing business—especially within the tech talent sector you’re focusing on—generative AI, and more recently, agentic AI, is a point of concern. Do you view this trend as a tough situation, or an opportunity? What countermeasures or approaches are you taking? Akamatsu: I think it’s definitely a storm and a critical situation, but more than that, I consider it a massive opportunity. As I mentioned earlier, standardized and routine tasks are increasingly being replaced by AI, and I can already feel that replacement happening in reality. However, if we just continue with the same kind of HR services we’ve offered up to now, I believe our company will undoubtedly disappear. On the other hand, I can feel a steady, upward trend in the demand for talent who can utilize data, talent who can implement AI into businesses, and talent with the level of communication and interpersonal skills that AI cannot replace. In that sense, if opzt itself can change and ride this wave, I believe we could be catching a very massive wave indeed. At our company, we are trying to develop talent capable of using AI even in non-engineering roles like administration, management, and recruitment, beyond just AI specialists and data scientists. By educating people to be on the side that uses AI rather than being used by it, I hope to create a differentiation strategy not found elsewhere. ◆Three New Initiatives for Further Growth Sugihara: Thank you. Are there any specific new initiatives you are currently working on for the further growth of your business? Akamatsu: There are three main things. First, as we discussed earlier, we are prioritizing the growth of our AI and data business, as well as the infrastructure sector surrounding data centers. Second, instead of dispatching individuals one by one, we are steadily increasing contracts with higher added value through outsourcing, where we provide support as a team. Third, even within our existing HR services, we are utilizing AI to enhance productivity in tasks such as recruitment, interviews, and staff follow-ups. Sugihara: Are there clients who need an entire team to be dispatched? Akamatsu: There actually are. Right now, engineers with those specific skills are either no longer available, or their rates have become expensive. So, we are seeing an increase in cases where we form and dispatch a team combining experienced professionals with the young talent we are training. As they grow, we add the next wave of new staff to the team, creating a cycle of continuous on-site training. Sugihara: I see, the younger members gain experience working alongside their mentors on the same job and in the same field with the same client, building their skills to eventually become leaders themselves. Akamatsu: Right. Our clients are also unable to train such talent themselves, so there is a strong demand to outsource the whole process to us. While this system can make things difficult sometimes, it allows our company to bring in inexperienced individuals, so we have recently been proposing to send whole teams to client companies quite often. Sugihara: Indeed, while sending someone individually helps that specific person build skills and experience, it raises the question of whether know-how is accumulating within the company itself. Usually, that person would have to come back and act as an instructor for internal training. But that training time doesn’t translate to revenue right away. Instead of making them just play the role of a teacher, they are essentially providing on-the-job training for younger members while both are getting paid by the client, and they themselves learn something through that, as well. Akamatsu: Exactly. So we are rapidly expanding this method right now. Interview conducted by D-POPS GROUP’s advisor Genta Sugihara. opzt, Inc.

[Venture Ecosystem Case Study] The Power of Three Arrows
“One Tech World”, a Development Alliance Formed by Three IT Companies “We lack engineers.” “One company alone can’t handle enterprise-scale projects.” These are the recurring problems in an IT industry facing severe labor shortages and increasingly complex project requirements. To address these challenges, three IT companies within D-POPS GROUP joined forces in May 2024 to form “One Tech World”, a strategic development alliance designed to leverage their collective strengths. The alliance consists of techbeans inc., an AI-leading company specializing in system development and AI solutions; @SOLUTION, the founding architect of this alliance, and a powerhouse in system development, infrastructure, mobile apps, and consulting; and idealump Co., Ltd, experts in web service development, UI/UX design, and other creative productions. This article explores how these three companies generate group synergy to secure large-scale enterprise contracts that would be unfeasible for any of them to obtain individually. 1. The “Wall” for Small to Mid-Sized IT Firms Certain areas of business are inaccessible for individual IT companies except for larger ones due to three main factors. ①Chronic Talent Shortages Large-scale projects require a massive headcount. Many firms must decline lucrative opportunities simply because they lack the internal resources. ②The Jack-of-All-Trades Trap Modern projects require a diverse elite skill set—PMs, designers, frontend/backend specialists, and infrastructure engineers. High-level mastery of every field within one company is rare. ③Ceiling on Internal Education Relying solely on internal projects limits a junior engineer’s growth. There are not many opportunities to learn from veteran engineers at other companies, so from an educational standpoint, they cannot overcome the limitations of in-house-only training. 2. The “Three Arrows” Concept: Unbreakable When Bundled There is a Japanese parable about “Three Arrows”, where a single arrow is easily broken but three held together are not. ①Exceeding the Limits of One To solve the challenges mentioned above, we arrived at a clear conclusion. By forming an alliance between the three IT companies within our group, we could flexibly handle large-scale projects that would be impossible for a single company to manage alone. Just like the Three Arrows—where a project that might snap a single firm’s resources can be successfully supported when three firms are bundled together—this vision was set into motion by a call to action from our organizer, @SOLUTION. ②The Right Talent, at the Right Time By forming this alliance, we can assign engineers across company lines, making it possible to take on project scales that a single firm simply could not accept. In an era where the shortage of IT talent is a major social issue, our ability to mobilize a large workforce all at once whenever necessary is a significant competitive advantage. ③Bringing Together Our Strong Points We are able to demonstrate our synergistic strength by combining the specific expertises of each company, including project management and direction, design, creative, frontend, backend, AI implementation, etc. Furthermore, skill sets that are difficult to assemble within a single organization can be fully covered when our three companies collaborate, vastly expanding the technical domains we can handle. ④Cultivating Talent Across Company Borders When veterans from one company work together with junior engineers from another on the same project, it creates growth opportunities that cannot be found within a single firm. Exposure to the different corporate cultures and technical approaches of other companies provides engineers with invaluable professional experience that accelerates their development. 3. The Three Coming Together: The Birth of “One Tech World” ①Why We Chose the Alliance Model We chose this system over a simple outsourcing relationship to ensure speed and quality by collaborating on a daily basis, rather than searching for new partners for every individual project. We believed that by teaming up with trusted colleagues who understand each other’s strengths and weaknesses, we could provide significantly higher value to our clients. ②Agility Through a Horizontal Structure By accepting projects as a horizontal alliance of three equals, we are able to keep the commercial flow simple and costs low while maintaining a flexible team structure. We have established a system where the primary contractor serves as the single point of contact while the alliance as a whole manages the project. ③Speed and Simplicity of Communication We utilize tools such as Slack to ensure smooth communication between our three companies. We also place a heavy emphasis on creating systems for information sharing and problem-solving through regular meetings. This commitment to open communication has been the key to increasing our collaborative speed. ④Development Rules as a Common Language We are actively developing standardized development rules for the alliance, clarifying the boundaries of responsibility and standardizing project management protocols. When different companies work together, keeping a set of rules that we have in common is essential for guaranteeing high-quality output. ⑤Keeping Everyone Up-to-date with AI Led by techbeans, we hold AI-related study sessions to create an environment where employees from all three companies can acquire AI utilization skills. As an AI-leading company, techbeans also actively publishes blogs and interviews, helping to drive AI adoption across the entire alliance. 4.The Journey to Launching: Inevitability, Rather than Coincidence Pre-2020 (Laying the Groundwork for Collaboration) The birth of One Tech World was preceded by a history of collaboration within the group. Around 2020, techbeans and @SOLUTION participated in the development of “DAMO”, the proprietary CRM system for D-POPS. This period allowed us to accumulate a track record of successful joint projects, cultivating the fertile ground necessary for a deep-seated partnership. December 2023 (Adding the Power of Creativity) idealump, a firm with significant strengths in design and creative production, joined D-POPS GROUP. This expanded the group’s IT capabilities into a three-company system, completing a lineup that could cover everything from technical development to high-end design. May 2024 (The Alliance Starts Moving) Following a call to action by @SOLUTION, the One Tech World development alliance was formally established between the three companies. Group synergy was demonstrated immediately, with idealump taking charge of renewing D-POPS GROUP’s corporate website during the same period. 2024–2025 (Expanding to Over 20 Collaborative Projects in 18 Months) In the year and a half or so since the alliance’s inception, the number of collaborative projects within the group reached approximately 20. By establishing a solid communication infrastructure, we have realized a higher speed of collaboration than we ever had before. Honestly, the sense of momentum we are experiencing is unlike anything any of us felt in the past. November 2025 (Stepping Outward: DXPO Exhibition) One Tech World made its debut as a unified entity by co-exhibiting at a major IT seminar event series in Japan called DXPO. By highlighting our strengths as an alliance—such as our AI-integrated products and our deep pool of talented engineers—we are working to increase our appeal among external clients. 5. Future Challenges: Racing Through the AI Era as a Unified Trio ①Overcoming the “Turning Point” in Development Since the launch of the alliance, we have successfully driven more than 20 collaborative projects within the group. Through continuous efforts to streamline communication, we have achieved a level of collaborative speed that we’ve never experienced before. This has made it possible for us to handle projects of a scale and scope that would have been impossible for a single company to manage alone. ②Accelerating Development with AI The development landscape is currently at a major crossroads. As the industry shifts toward accelerating development speeds through AI, techbeans—as an AI-leading company—is spearheading this movement by publishing AI-related blogs and interviews and hosting internal study sessions for the alliance. By supporting the employees of all three companies in mastering AI, we are significantly strengthening the collective development power of the entire alliance. ③Becoming the “Preferred Choice” through Creative Excellence Among the three companies, idealump possesses particularly strong design and creative capabilities, serving as a powerful asset when approaching external clients. While it comes a bit later than our initial launch a year and a half ago, we plan to significantly strengthen our inbound marketing strategy in 2026. We aim to capture new markets by fully utilizing the unique strengths of our three-member partnership. ④Opening the Door to Enterprise-Level Projects The alliance was brought together by the vision of the originator, @SOLUTION. Much like the bundling of three arrows, this partnership has turned the dream of approaching major corporations—once impossible for a single firm—into a reality. In an era of chronic IT talent shortages, the ability to mobilize a large, skilled workforce the moment it is needed serves as a massive competitive advantage. ⑤Expanding Collaboration with External Partners Moving forward, we plan to invite partner companies from outside D-POPS GROUP to participate in our projects. However, this will not be open to everyone. We will only admit partners who meet the specific high standards set by One Tech World. Our goal is not simply to become a large IT organization, but to be a collective of highly skilled IT talent and, above all, a group of companies that clients can trust implicitly. We will continue to increase the value of this alliance by balancing the expansion of our scale with strict quality assurance. 6. Summary: Choosing to “Bundle Together” In this article, we have summarized the initiatives of One Tech World, the development alliance formed by three IT companies within D-POPS GROUP. In this era when IT is accelerating faster and faster, issues that a single company cannot solve alone are increasing. Just as in the Three Arrows parable, by leveraging group synergy and mutually complementing each other’s resources, expertise, and talent cultivation, One Tech World represents a new collaborative model that IT companies in the future will be pursuing desperately. D-POPS GROUP will continue to harness the potential of our Venture Ecosystem, striving to make new, valuable contributions to society through the sharing and nurturing of exceptional IT talent. techbeans inc.
