Japan’s Three Megabanks to Launch Joint Yen Stablecoin by March 2027
MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation have formalized a joint council with the ambitious goal of developing and co-issuing a yen-backed cryptocurrency stablecoin by the end of Japan’s fiscal year 2026, which concludes in March 2027.
The stablecoin will operate under a trust agreement, with all three banking giants serving as joint settlors. A designated trust bank or a similar institution will act as the trustee. This initiative is not a pilot program; rather, it represents a significant commitment from three systemically important financial institutions to share infrastructure for this endeavor.
This move signals a substantial step toward stablecoin adoption by Japan’s largest banks. The three leading financial groups in Japan – MUFG, Sumitomo Mitsui Financial Group, and Mizuho – are collectively planning to issue stablecoins by the March 2027 deadline.
The initiative is being conducted under the Financial Services Agency’s (FSA) Payment Innovation Project. It follows a pilot program conducted in late 2025, which assessed the feasibility of multi-bank stablecoin co-issuance, examining whether it could be executed “legally and appropriately,” according to the banks. The successful outcome of this pilot has evidently paved the way for the current joint venture.
Collectively, MUFG, Mizuho, and SMBC manage assets exceeding $7 trillion, positioning this as the most significant institutional stablecoin initiative in Asia to date.
Japan’s regulatory framework for stablecoins solidified in June 2023 with amendments to the Payment Services Act. These amendments introduced a formal licensing regime for fiat-pegged stablecoins, classifying them as electronic payment instruments.
Current legislation restricts the domestic issuance of stablecoins to three categories of entities: licensed banks, trust companies or trust banks, and registered fund transfer service providers. This regulatory structure provides the established megabanks with a clear pathway to enter the market.
The FSA’s Payment Innovation Project, part of the FinTech Proof-of-Concept Hub that has been operational since 2017, served as the formal channel for the late-2025 pilot.
Updated amendments to the Payment Services Act, which took full effect on June 13, 2026, have strengthened travel-rule obligations for cross-border transactions and reinforced the FSA’s enforcement capabilities. Furthermore, from June 1, 2026, foreign trust-type stablecoins are permitted to operate in Japan as electronic payment instruments under a revised Cabinet Office Ordinance, provided they meet the FSA’s licensing, collateral management, and audit standards.
Specific reserve rules allow trust stablecoin issuers to invest up to 50% of their reserves in short-term Japanese government bonds. The megabank yen stablecoin is expected to be fully reserved, with assets comprising cash and Japanese government bonds held in trust, adhering strictly to the FSA’s requirements for asset segregation and redemption at par.
The megabanks are entering a yen stablecoin market that has seen rapid development since regulatory clarity emerged in 2023. JPYC Inc. launched Japan’s first legally recognized yen-denominated stablecoin, JPYC, in October 2025. The FSA subsequently classified it under the same regulated payment services framework as popular payment services like PayPay and Rakuten Pay in April 2026, indicating the growing mainstream acceptance of such products.
In February 2026, SBI Holdings and Startale Group introduced JPYSC, a yen stablecoin backed by a trust bank and issued by SBI Shinsei Trust Bank, targeting institutional and cross-border use cases. The Japan Blockchain Foundation announced EJPY in May 2026, which is slated to be issued on the Japan Open Chain and Ethereum networks.
On the dollar side, major financial institutions are actively pursuing bank-issued crypto ventures. USDC became the first dollar-pegged stablecoin approved in Japan in March 2025, issued by SBI. Additionally, Ripple and SBI Holdings have announced plans to launch RLUSD in Japan.
The key differentiator of the megabank co-issuance model lies in its regulatory weight rather than technological innovation. While existing stablecoins like JPYC and JPYSC are compliant products, a jointly branded yen stablecoin from all three of Japan’s dominant banking groups carries a distinct level of institutional credibility and the potential for significantly larger settlement volumes.
