Japan’s three largest banks are moving closer to launching a jointly issued stablecoin, marking one of the country’s most significant steps toward blockchain-based payments and digital financial infrastructure.
Key Takeaways
- MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation plan to launch a jointly issued stablecoin during fiscal year 2026, ending in March 2027.
- The banks will establish a dedicated council to oversee governance, operations, and commercialization of the project.
- The stablecoin will be issued under a trust based structure supported by Japan’s regulatory framework.
- The initiative aims to improve cross-border payments, corporate settlements, and treasury operations while accelerating stablecoin adoption in mainstream finance.
What Happened?
Japan’s three megabanks have reached a fundamental agreement to jointly issue a stablecoin and begin live commercial transactions by the end of fiscal year 2026. The project represents a major collaboration among the country’s largest financial institutions and reflects growing confidence in blockchain-based payment systems under Japan’s evolving regulatory framework.
According to announcements from the participating banks, the initiative will focus on developing a secure and compliant digital payment infrastructure capable of supporting a wide range of commercial use cases.

Japan’s Largest Banks Unite Behind a Single Stablecoin Project
MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation (SMBC) are preparing to move beyond pilot testing and into commercial deployment of a jointly issued stablecoin.
The three banks plan to establish a dedicated consultative council that will examine governance structures, operational frameworks, and practical transaction models before the planned launch period. A basic agreement is expected to be finalized as the banks deepen cooperation on the project.
The initiative stands out because it brings together Japan’s most influential banking institutions under a single digital asset strategy. Collectively, the three banks account for a significant share of the country’s banking sector, making the project one of the largest bank-led stablecoin efforts globally.
Stablecoin Will Use a Trust Based Structure
The stablecoin is expected to be issued under a trust agreement, with the three megabanks serving as joint settlors. A trust bank will act as trustee and oversee the underlying reserves.
Reports indicate that the project will utilize Progmat, the digital asset issuance platform originally developed by MUFG before becoming an independent industry platform.
The structure is designed to comply with Japan’s Payment Services Act, which introduced a legal framework for stablecoins through the concept of electronic payment instruments. Under this model, stablecoins are backed by fiat currency held in trust accounts, helping ensure redemption rights for users.
This regulatory approach has helped Japan become one of the most advanced jurisdictions for stablecoin development among major economies.
Focus on Corporate and Cross-Border Payments
While the banks have not yet disclosed all details regarding users, settlement networks, or redemption mechanisms, the project’s primary focus appears to be business to business payments and cross-border transactions.
The broader initiative, known as Project Pax, aims to modernize payment infrastructure by reducing reliance on traditional systems used for domestic and international settlements.
The participating banks reportedly target approximately one trillion yen in transaction volume by 2028, highlighting the scale of their ambitions.
A yen denominated stablecoin is expected to launch first, while a U.S. dollar version could follow later.
Regulatory Support Fuels Momentum
The project has received support from Japan’s Financial Services Agency, which has worked with the banks since late 2025 through pilot programs and regulatory initiatives.
The stablecoin effort is also linked to the FSA’s FinTech Proof of Concept Hub, which supports experimentation with innovative financial technologies.
Japan’s regulatory clarity has encouraged several organizations to enter the stablecoin sector. Recent developments include the launch of JPYC, the introduction of JPYSC by SBI Holdings and Startale Group, and plans for EJPY by the Japan Blockchain Foundation.
Unlike some markets where regulatory uncertainty has slowed institutional adoption, Japan has focused on creating clear compliance pathways for banks and financial institutions seeking to issue digital assets.
Why This Matters for the Future of Digital Payments?
The joint stablecoin initiative signals a shift from isolated blockchain experiments toward coordinated commercial deployment by traditional financial institutions.
If successful, the project could expand stablecoin usage far beyond cryptocurrency trading and into everyday financial operations such as treasury management, supply chain payments, corporate settlements, and international money transfers.
The involvement of major enterprises is already emerging. Mitsubishi Corporation is expected to explore use cases across its global network of subsidiaries, providing an early test of how blockchain-based settlement can support large scale corporate activity.
As banks around the world continue evaluating tokenized deposits and digital payment infrastructure, Japan’s coordinated approach may offer a model for how stablecoins can be integrated into the traditional financial system while maintaining strong regulatory oversight.
CoinLaw’s Takeaway
In my experience, one of the biggest barriers to stablecoin adoption has always been trust and regulatory certainty. What stands out here is that Japan is not leaving innovation entirely to crypto firms or startups. Instead, the country’s largest banks are building the infrastructure themselves under a clear legal framework. I found this particularly significant because it could create a blueprint for how traditional finance and blockchain technology can work together. If the project succeeds, it may become one of the strongest examples of real world stablecoin adoption driven by regulated financial institutions.
