According to reports from Japan, the country’s three largest banks—MUFG Bank, Sumitomo Mitsui Banking Corporation, and Mizuho Bank—are preparing to jointly launch a stablecoin pegged to the Japanese yen. The plan aims for rollout by the end of Japan’s 2026 fiscal year, which concludes in March 2027.
Agreement process and regulatory framework
Nikkei has reported that the three banks are close to signing a formal agreement. The parties are said to be planning the creation of a dedicated council that will determine operational details and commercial use cases for the token. However, the report notes that specifics regarding the technical architecture and implementation model have not yet been disclosed.
Japan’s Financial Services Agency (FSA) has reportedly been involved in the process since at least November 2025. At that time, the three banks embarked on initial tests under regulatory oversight for their joint stablecoin initiative. The FSA remains Japan’s primary financial regulator, overseeing banking, securities, and insurance markets.
While the general direction, timeline, and regulatory framework of the joint stablecoin plan from the three major banks have taken shape, questions around areas such as use cases, technical infrastructure, and custody arrangements remain unresolved.
The biggest uncertainties for the project include whether the stablecoin will be made available to individual consumers, corporate clients, or both. Details are also sparse regarding its capacity for cross-border payments, compatibility with other systems, reserve structures, and how assets will be held.
Japan’s approach to stablecoins
In 2022, Japan enacted regulations officially defining stablecoins as a digital form of money and restricting their issuance rights to licensed banks and trust companies. This regulatory framework signals that the joint product is not merely a pilot project, but a step toward integrating stablecoins into the country’s financial infrastructure.
A previous Nikkei report indicated that the FSA encouraged the three banks to collaborate rather than release competing products individually. This approach appears to have accelerated the shift from isolated experiments to the development of a single, unified stablecoin.
Potential global market impact
This development comes as traditional financial institutions globally are intensifying efforts around tokenized deposits and fiat-backed stablecoins. Hong Kong’s monetary authority, for example, also announced expectations for stablecoin launches within its jurisdiction later this year.
In the context of Japan, MUFG Bank, SMBC, and Mizuho Bank command a significant share of domestic deposits and payment flows. Backed by these major banks and overseen by the FSA, a yen-denominated stablecoin could shift some settlement transactions away from currently dominant dollar-based stablecoins like USDT and USDC.
However, because bank-issued stablecoins typically feature controlled access and narrower use cases, their contribution to global liquidity could be limited. Still, such structures are likely to attract increased attention among corporate treasury and institutional payment sectors.
