Japan's three largest banking groups are moving their shared stablecoin work from pilot planning toward live commercial use.

MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation said Wednesday that they aim to conduct actual commercial transactions during fiscal 2026 using a stablecoin issued under a trust agreement. Japan's fiscal year runs through March 2027, making the target window more specific than a general future roadmap.

The banks also signed a memorandum of understanding to create a voluntary council for the project. That group will examine the issuance infrastructure, operating rules, governance structure, and system design needed to put the stablecoin into practical use. The joint announcement says the three banks would act as joint settlors, while a trust bank or similar institution would serve as trustee.

The initiative follows earlier discussions tied to a stablecoin proof-of-concept selected for support by Japan's Financial Services Agency's FinTech Proof-of-Concept Hub in November 2025. The banks framed the new council as a way to continue that work while accounting for laws, regulations, and market conditions.

For Japan's stablecoin market, the important point is not only that large banks are involved. It is that they are trying to coordinate on common infrastructure rather than each building separate payment tokens. If the project reaches live transactions, it could become a regulated bank-led test case for enterprise blockchain settlement in Japan.
