Japan's Three Biggest Banks Complete Joint Yen Stablecoin Payment Trial
Key Takeaways
- •MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation completed a joint trial showing that a shared yen stablecoin framework can handle issuance, transfer, and redemption.
- •The trial, held from July 17 to 23, 2026, tested payments between Mitsubishi Corporation's Japanese headquarters and its overseas offices.
- •The stablecoins were issued under Japan's trust-based digital asset regime, backed by bank deposits, with identity verification restricting access and compliance checks covering money laundering and terrorist financing risks.
- •The project was selected in November 2025 for support under Japan's Financial Services Agency payment innovation program.
- •The participating banks intend to pursue commercial deployment within the fiscal year ending March 2027, but governance arrangements remain to be settled before any broad rollout.

Japan's three largest banking groups have completed a joint trial of a yen stablecoin, validating that the digital tokens can be issued, transferred, and redeemed under a shared framework. The findings, announced on October 16, 2026, bring blockchain-based cross-border payments closer to commercial use, and the participating banks now intend to move the system toward real-world business payments.
Major Banks Validate a Joint Stablecoin Framework
The experiment involved MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation — the core banking units of the country's three largest banking groups. The project also received support from Mitsubishi UFJ Trust and Banking Corporation and TISI, while Mitsubishi Corporation took part as the corporate test client.
Stablecoins are digital tokens designed to hold a stable value by being backed by an underlying asset — in this case, deposits denominated in yen.

According to the official announcement (PDF), the experiment took place from July 17 to July 23, 2026. The project had been selected for support by Japan's Financial Services Agency in November 2025 and was carried out under the agency's payment innovation program.
During the trial, participants examined payments between Mitsubishi Corporation's Japanese headquarters and its overseas offices. The process covered the full lifecycle of the tokens, from stablecoin issuance and transfer through to final redemption into cash. According to the findings, the results demonstrated that it is technically possible to apply the same framework to international business payments.
The project also addressed legal compliance, transaction security, and the prevention of financial crime. Participants specifically examined anti-money laundering measures and controls against terrorist financing — protections that remain essential for cross-border financial transactions involving digital assets.
The stablecoins were issued under Japan's regulatory regime for trust-based digital assets. That regime builds on amendments to the Payment Services Act that took effect in June 2023, which allowed institutions such as licensed banks and trust companies to issue stablecoins. The tokens were backed by bank deposits, and identity verification restricted who could access them. Together, these safeguards allowed the experiment to satisfy the relevant financial requirements.
Banks Push Blockchain-Based Payments Forward
Cross-border business payments have conventionally run through correspondent banking arrangements, in which funds pass through several intermediary institutions before reaching a recipient. Against that backdrop, the project may pave the way for Japan's banking sector to create shared digital payment infrastructure. Businesses may eventually adopt blockchain-based settlement systems alongside traditional payment methods, a shift that could give companies access to more efficient foreign exchange solutions for their international transactions.
Before any broad rollout, however, the participating banks must work out governance structures and prepare the system for real-world business applications. The successful test therefore marks technical advancement rather than the availability of a commercial service.
The banks are aiming to move toward commercial deals in the current fiscal year, which ends in March 2027 — a goal that brings the initiative closer to actual use. The announcement, however, does not confirm a completed commercial launch. The markers to watch are the governance arrangements the banks settle on and whether commercial transactions follow within the stated fiscal-year window.
Japan's financial institutions have been actively experimenting with blockchain technology for payments and other financial services. This collaborative effort reflects a push to modernize settlement processes while maintaining regulatory oversight, and it provides a glimpse of how stablecoin operations might be coordinated across multiple banks.
A common framework could harmonize procedures and streamline cross-border business payments, while cooperation may reduce the number of duplicated individual bank systems. Actual benefits, however, will depend on implementation costs, regulatory requirements, and business adoption.
Overall, the project represents a step toward coordinated payments with yen stablecoins. Its future success will hinge on secure operations, regulatory compliance, and genuine business needs. If the framework is put into practice successfully, it may offer companies an additional alternative for international settlements.
