- Japan’s top three banks plan a yen-backed stablecoin launch by March 2027 under FSA oversight.
- MUFG, SMBC, and Mizuho are forming a council to coordinate stablecoin operations and use cases.
- Key details on reserves, custody, and cross-border payments remain undecided ahead of launch.
Japan’s three largest banking groups are moving closer to issuing an asset-backed stablecoin, marking a new stage in the country’s efforts to integrate blockchain-based payment systems into the traditional financial sector.
According to reports, MUFG Bank, Sumitomo Mitsui Banking Corporation (SMBC), and Mizuho Bank are preparing to launch a yen-pegged stablecoin before the end of Japan’s fiscal year 2026 in March 2027.
The project has been developed under the supervision of Japan’s Financial Services Agency (FSA), with the three institutions working toward a formal agreement that would establish a framework for issuance and future operations.
The initiative brings together three of Japan’s largest financial institutions, which collectively manage more than $7 trillion in assets.
Banks Prepare Governance Structure
According to a report, the three banks are nearing the signing of a formal agreement that would pave the way for the creation of a dedicated council. The proposed body would be responsible for coordinating operational matters and exploring potential commercial applications for the stablecoin.
The discussions follow earlier testing efforts that began in late 2025. During that period, the participating banks conducted initial trials of a jointly issued stablecoin under Japan’s financial regulator’s oversight.
Although the project timeline has become clearer, several operational questions remain unresolved. The banks have not announced how the stablecoin will function in practice or disclosed the blockchain infrastructure that may support the initiative.
In addition, the banks have not provided information regarding reserve management, custodial arrangements, or interoperability with payment systems outside Japan.
Japan FSA Evaluates Joint Stablecoin Framework
Japan’s Financial Services Agency has played a role in the project’s development since at least November 2025, when participating institutions began testing the concept. The regulator’s involvement has centered on evaluating whether a jointly issued stablecoin could operate within existing regulatory frameworks.
