Japan’s digital banking landscape is undergoing a transformation as Minna Bank, the country’s first fully digital bank and a subsidiary of Fukuoka Financial Group, steps into the world of blockchain-based finance. In a strategic move to modernize everyday financial services, the bank has launched a joint research initiative with leading blockchain infrastructure provider Fireblocks, Solana Japan, and prominent Japanese technology firm TIS. The project aims to explore real-world applications of stablecoins and Web3 wallets in mainstream banking and consumer payments.
This collaboration marks a significant step toward integrating decentralized technologies into traditional financial systems in one of the world’s most regulated economies. With a focus on practicality and scalability, the research will evaluate how blockchain-powered solutions can enhance cross-border payments, real-world asset (RWA) transactions, and daily digital spending.
Exploring Real-World Applications of Stablecoins
The joint study is designed to assess multiple use cases where stablecoins—digital currencies pegged to fiat assets like the Japanese yen—could offer tangible benefits over conventional banking methods.
Cross-Border Payments
One of the primary focuses is improving the speed and reducing the cost of international money transfers. Traditional remittance channels often involve multiple intermediaries, resulting in delays and high fees. By leveraging blockchain networks such as Solana, which supports fast and low-cost transactions, the consortium aims to create a more efficient alternative for sending money across borders.
Using yen-pegged stablecoins issued on-chain could enable near-instant settlements while maintaining price stability—addressing two major pain points in global remittances.
Real-World Asset Tokenization
Another promising area of exploration is the tokenization of real-world assets. This involves representing physical or legal assets—such as real estate, bonds, or invoices—as digital tokens on a blockchain. These tokenized assets can then be traded more efficiently, with greater transparency and reduced administrative overhead.
Minna Bank, together with its partners, will investigate how financial institutions can issue, manage, and settle RWA-backed instruments using stablecoin settlements. This could open doors to new forms of liquidity and investment accessibility within Japan’s tightly regulated financial environment.
Daily Digital Payments
Beyond institutional use cases, the project also targets consumer-facing innovations. The integration of Web3 wallets into everyday banking could allow users to make instant peer-to-peer (P2P) payments, pay bills, or shop online using stablecoins—all within a secure and regulated framework.
The goal is to design an intuitive user experience that bridges the gap between traditional finance (TradFi) and decentralized finance (DeFi), making digital assets accessible even to non-technical users.

Technical Evaluation on Solana Blockchain
A key component of the research involves assessing the technical feasibility of issuing and managing stablecoins on the Solana blockchain. Known for its high throughput—capable of processing tens of thousands of transactions per second—and low transaction fees, Solana presents an attractive infrastructure for scalable financial applications.
Solana Japan, the local arm of the Solana ecosystem, plays a crucial role in ensuring regulatory alignment and community engagement. Their involvement helps tailor global blockchain innovations to meet Japan’s unique compliance standards, including anti-money laundering (AML) and know-your-customer (KYC) requirements.
Meanwhile, Fireblocks brings its enterprise-grade custody and settlement infrastructure to the table. Its secure wallet management system ensures that digital assets are protected against theft and unauthorized access—critical for any financial institution venturing into crypto.
TIS, a major IT services provider in Japan, contributes its deep expertise in system integration and financial technology development. Their role includes designing backend systems that seamlessly connect traditional banking platforms with blockchain networks.
Bridging Web3 Wallets and Consumer Finance
A major challenge in mainstream crypto adoption is usability. Most existing Web3 wallets require users to manage private keys, understand gas fees, and navigate complex interfaces—barriers that deter average consumers.
This trial seeks to develop a more user-friendly digital wallet experience that integrates directly with Minna Bank’s services. Imagine a mobile banking app where users can switch between yen balances and yen-backed stablecoins with a single tap, send money instantly to friends or merchants, or earn yield on idle digital assets—all without leaving a familiar interface.
Such hybrid wallets could serve as gateways to broader financial inclusion, especially for younger generations already comfortable with digital-first experiences.

Frequently Asked Questions (FAQ)
Q: What is a stablecoin?
A: A stablecoin is a type of cryptocurrency designed to maintain a stable value by being pegged to a reserve asset, such as a fiat currency like the Japanese yen or U.S. dollar. This stability makes them ideal for payments, remittances, and storing value without the volatility associated with other cryptocurrencies.
Q: Why is Minna Bank testing stablecoins on Solana?
A: Solana offers high-speed transactions and low fees, making it well-suited for mass-market financial applications. By testing on Solana, Minna Bank can evaluate whether this blockchain can support scalable, real-time payment systems under real-world conditions.
Q: Are these digital wallets open to the public now?
A: Not yet. This is currently a research and trial phase conducted by Minna Bank and its partners. There is no public launch date announced at this time. The results of the study will inform future product development and regulatory considerations.
Q: Will this involve cryptocurrency speculation or trading?
A: No. The focus of this initiative is on practical financial services—not speculative trading. The goal is to use blockchain technology to improve efficiency in payments, asset management, and customer experience within a regulated banking environment.
Q: How do Fireblocks and TIS contribute to this project?
A: Fireblocks provides secure digital asset custody and transfer infrastructure, ensuring that funds are protected from hacks and fraud. TIS contributes technical integration expertise, helping bridge legacy banking systems with modern blockchain networks.
Strategic Implications for Japan’s Financial Future
Japan has long been at the forefront of fintech innovation while maintaining strict regulatory oversight. The involvement of a licensed digital bank like Minna Bank signals growing institutional confidence in blockchain technology.
If successful, this pilot could pave the way for wider adoption of stablecoins in Japan’s financial ecosystem—potentially influencing policy decisions around central bank digital currencies (CBDCs) and private-sector digital money issuance.
Moreover, it highlights a global trend: traditional financial institutions are no longer观望 (on the sidelines). They are actively experimenting with decentralized technologies to stay competitive in an increasingly digital economy.

Conclusion
Minna Bank’s collaboration with Fireblocks, Solana Japan, and TIS represents more than just a technical experiment—it’s a bold step toward redefining what digital banking can be in the Web3 era. By focusing on real-world utility, security, and user experience, this initiative could set a new benchmark for how banks integrate blockchain into everyday finance.
As trials progress, all eyes will be on Japan to see if this model can deliver scalable, compliant, and user-friendly financial solutions that balance innovation with trust.
