Sota Watanabe is on a mission to change the trajectory of the digital economy and rebuild it on the foundations of blockchain. The visionary CEO of Startale Group has already emerged as one of the central architects of Japan’s Web3 strategy, but it was in the U.S. that he first formulated his plans. During his formative days in Silicon Valley, he realized that global finance is missing a key ingredient – a decentralized foundation where truth is no longer mediated, but codified instead.
As he embarks on a new chapter with Startale’s expansion into the U.S., Watanabe aims to help blockchain shrug off its speculative image and transform it into the invisible backend of the modern internet. To do this, Startale is building a vertically-integrated, full-stack ecosystem that encompasses everything from the wallets to the Layer 2 infrastructure and regulated stablecoins. It’s part of an all-out effort to construct a resilient and compliant digital civilization that replaces the complexities of blockchain with the intuitive, reliable and trusted user experience that finance demands.
1. You got your first taste of blockchain in San Francisco at Chronicled, and it seems like that was clearly a formative experience for you. What was the specific moment during your time there that made you realize that you needed to dedicate your career to advancing blockchain as the infrastructure for the future of finance?
Chronicled was a real eye-opener for me, because it showed me how the concept of “trust,” which was traditionally always the domain of slow-moving institutions, is far more efficient and reliable when it’s codified. In fact, it eliminates the need for trust.
There wasn’t a single lightbulb moment; it was more just the slow realization that blockchain is more than just fintech, with the potential to become a more efficient layer for establishing “truth.” And I knew that if Japan’s economy didn’t adopt this, if it wasn’t at the forefront of this revolution, it could be left behind. So that’s when I determined that I would start building its foundation in my home country.
2: You’ve become a central figure in Japan’s national Web3 strategy, working closely with the government. What are the main challenges you continue to face in positioning Japan as a leader in the global blockchain economy?
I think the primary challenge is the need to make blockchain "invisible” so we can transform it into a new backend for the internet. The skepticism of the past is no longer there, but there’s still this perception that Web3 is some new asset class for trading. But that’s not what it is.
We have to stop selling “crypto” and focus on the idea of seamless digital experiences, where users don’t even realize they’re interacting with a blockchain. This gap between high-level policy and everyday utility is where the real friction remains.
3: Startale’s strategy appears to be to try to own the full-stack, with the Startale application, the infrastructure via Soneium and Strium, and stablecoins like JPYSC and USDSC and lastly applications like Startale App. Why is this kind of vertical integration necessary?
Vertical integration isn't just a business preference. It's an architectural necessity. The moment you reach institutional scale, fragmentation becomes friction, and friction becomes cost. Companies that don't own or tightly coordinate their infrastructure end up as tenants in someone else's system.
By owning the full stack, we achieve strategic sovereignty. If you’re relying on external infrastructure then your roadmap is always going to be subject to someone else’s priorities. By integrating Soneium and Strium with the Startale App and our stablecoins, we are building an ecosystem that’s resilient and optimized for institutional use. This means we can move faster, innovate much deeper and ensure that whatever value is generated in our ecosystem stays within it.
Earlier blockchain ecosystems were highly modular. Strong networks but disconnected wallets, or vibrant App ecosystems sitting on top of complex onboarding flows. That fragmentation is what we're solving. By owning the full stack, we can deliver a seamless experience where users don't have to think about bridges or pay gas in different tokens just to make a simple transaction.
4: You created the JPYSC stablecoin in collaboration with SBI Holdings. What’s the main purpose of having a Yen-backed stablecoin in a world that’s dominated by USD-pegged tokens? Who is going to need to use JPYSC?
Japan's economy runs on the yen, and Japanese institutions aren't going to settle locally in USDT or USDC. JPYSC is regulated and designed for institutional utility: B2B settlements, tokenized securities, treasury operations. It's the compliant bridge that lets the Japanese economy move onchain.
The bigger idea isn't just tokenizing currencies. It's creating programmable liquidity that moves across time zones, markets, and institutional needs. I think every major fiat currency will eventually have a regulated, compliant stablecoin twin. The question is which jurisdictions get there first.
5: Startale recently expanded to the U.S. to help accelerate its global expansion. What can you bring to the U.S. crypto market that domestic crypto companies have been unable to deliver, and what challenges will Startale face in doing this?
Startale brings an emphasis on trust, compliance, and long-term reliability to an American crypto economy that has always been more focused on speculative use cases in DeFi, memecoins, and so on. Many US crypto firms are native to the DeFi world and built primarily for crypto-native audiences and so they are less focused on the kind of structure we bring. We specialize in onboarding the world's largest corporations, with an emphasis on trust, compliance, and long-term reliability.
That said, the US brings things Asia can't replicate at the same scale. Speed, capital formation, and global ambition. To succeed here, you have to be more aggressive, because the mentality is to dominate the market. Japan brings precision, regulatory clarity, and deep institutional integration. The two strengths are complementary, and Startale is positioned to combine them.
The main challenge is the complex regulatory environment in the U.S., which isn’t as mature as Japan’s. But it’s not our job to try and change this so much as to just demonstrate that it’s possible to integrate Web3 into the existing economy and bring it on-chain.
6: Startale recently raised $63M in funding and outlined a multipronged strategy that includes scaling Strium for tokenized security and RWAs, expanding adoption of JPYSC and USDSC, leveraging Soneium to tap into Sony’s global audience, and transforming the Startale app into a “superapp”. What’s so critical about the interplay here between these products?
Each of these products solves a different layer of the same problem, and they only work because they're built to operate together. Strium is the regulated environment for tokenized securities and real-world assets. JPYSC and USDSC are the compliant settlement tokens institutions need to transact in that environment. Soneium brings IP and a captive audience for engagement. And the Startale App is the gateway that makes all of it accessible, abstracting the complexity of wallets, bridges, and gas.
Pulled apart, each piece is useful but limited. Pulled together, they form an integrated system where institutions can issue, settle, and distribute onchain without ever leaving the stack. That's the goal: not just infrastructure, but a digital civilization where the user doesn't even know they're interacting with a blockchain.
The dawn of a digital financial revolution?
Building this civilization is going to be a monumental task, but Startale has already shown it’s possible by integrating blockchain into the Japanese economy. The next step is to do this at a much greater scale, but Sota already has the U.S. economy sitting in his crosshairs, paving the way for an ecosystem where borders no longer exist. In this future, buzzwords like “crypto” will fade away, as institutional assets, daily payments and entertainment IP flows through a single yet invisible stack.
The best thing about Sota’s plan is that, if he succeeds, we probably won’t even know it. The future of finance will look much like it is now, only it will function with unprecedented efficiency, with greater speeds, lower costs and more opportunities for all.
