The development marks one of the biggest stablecoin news stories from Japan this year, as traditional financial institutions deepen their involvement in digital asset infrastructure.
The three biggest banks in Japan, Mitsubishi UFJ, Sumitomo Mitsui, and Mizuho, are partnering to issue a stablecoin pegged ato the Japanese Yen. The country’s leading media outlet, Nikkei, disclosed this in a news report.
According to Nikkei, the megabanks are still discussing plans for the stablecoin and want to launch it before the end of the 2026 financial year in March 2027.
The Nikkei report stated that the banks have been deliberating stablecoin issuance for some time. According to it, pilot tests began in November 2025, and the banks plan to establish a council to determine how the stablecoin will operate and be used.
Interestingly, the country’s financial regulator, the Financial Services Agency (FSA), is supervising the project and supervising it. FSA reportedly encouraged banks to collaborate and launch a single stablecoin rather than issue competing digital currencies.
With the three banks controlling over $8 trillion in assets, their involvement in stablecoins could mark a major adoption in the country. Japan has had a law on stablecoin since 2022, which restricts issuance to licensed trusts and banks
This mirrors a similarly planned project in the US, announced in 2025. Several of the biggest banks in the US, including Bank of America, JPMorgan Chase, Citigroup, and Wells Fargo, all said they were exploring a joint stablecoin.

While there have not been many updates since then, the US has already seen an improved regulatory environment for stablecoins with the passage of the GENIUS Act. Regulatory clarity represents a positive development for banks.
Meanwhile, a JPY-pegged stablecoin from Japan’s megabank could easily dominate the market for JPY stablecoins. Presently, CoinGecko data shows that the entire market cap for the JPY stablecoin is $42.8 million, with trading volume below $300,000.
Meanwhile, the move by Japanese banks only highlights the growing adoption of stablecoins, even by traditional financial institutions. While crypto firms such as Tether and Circle still dominate issuance, tradFi institutions are also getting more involved.
Payment processors such as Visa and MasterCard have focused on multiple stablecoin initiatives, including settlement infrastructure. Mastercard even acquired stablecoin infrastructure firm Bvnk for $1.8 billion as part of its stablecoin push.
Interestingly, there are also reports that the payments giants are currently discussing a stablecoin platform with Coinbase and Stripe. While details remain unclear, reports claim that it could be a consortium involving other companies.
Despite the rise in stablecoins adoption, the circulating supply has grown little in 2026 compared to previous years. Stablecoin supply was around $308 billion at the start of 2026.
The overall market cap currently stands at $317 billion, down almost $3 billion over the past seven days. Peak circulating supply was $322 billion, with USDT still maintaining a 58.91% dominance.
Recent stablecoin news developments suggest that regulatory clarity is encouraging more traditional financial institutions to explore blockchain-based payment systems.
