Mitsubishi UFJ Financial Group (MUFG), Sumitomo Mitsui Financial Group (SMBC) and Mizuho Financial Group said they will jointly issue a yen-denominated stablecoin by the end of Japan's current financial year, which closes in March 2027. The three banks will set up a council to design the operational framework, with the three lenders acting as joint settlors and a trust bank or similar institution serving as trustee, according to a statement on MUFG's website.
The plan lands with the Financial Services Agency already signalling support for a bank-led stablecoin as recently as November, and the ruling Liberal Democratic Party separately calling for the state to promote yen-based tokens. The three lenders together hold a dominant share of Japan's banking deposits, giving the project a balance-sheet base that dollar-pegged stablecoins have never had at launch.
Why it matters
Yen stablecoins are a rounding error in a global stablecoin market of roughly $311 billion — the most prominent, JPYC, sits at an $18 million market cap against USDT and USDC's combined 84% share. The reason that gap exists isn't technological; it's that no major issuer has stood behind a yen token with the kind of regulatory and balance-sheet credibility a bank consortium brings. MUFG, SMBC and Mizuho are precisely the kind of counterparties the FSA needs to onboard if yen settlement rails are ever to compete with dollar stablecoins for cross-border use.
Market impact
The near-term effect is on the yen stablecoin niche itself, where JPYC and a handful of smaller issuers currently compete. With three megabanks forming a single council and a trustee structure already mapped out, the bar for issuance moves from fintech experimentation to regulated banking infrastructure, narrowing the runway for independent yen stablecoin issuers. Watch the council's first published framework document and any FSA-issued guidance as the next milestone — the March 2027 target gives regulators roughly eighteen months to formalise the trust-bank model before launch.
Frequently asked questions

Mitsubishi UFJ Financial Group (MUFG), Sumitomo Mitsui Financial Group (SMBC) and Mizuho Financial Group. The three will act as joint settlors, with a trust bank or similar institution acting as trustee.
-
When will the yen stablecoin launch?
The three banks are targeting issuance by the end of Japan's current financial year, which closes in March 2027. They will first establish a council to design the operational framework.
-
How big is the yen stablecoin market today?
Yen-pegged stablecoins account for under $50 million of the roughly $311 billion global stablecoin sector. The largest, JPYC, has a market cap of around $18 million.
-
Who regulates stablecoins in Japan?

-
Why does a bank-led yen stablecoin matter?
Existing yen stablecoins are issued by fintechs without major bank backing. A consortium of MUFG, SMBC and Mizuho brings balance-sheet scale and regulatory standing that dollar stablecoin issuers like Tether and Circle never had at launch, raising the bar for independent yen issuers.
