Introduction
In an ambitious move anticipated to reshape the landscape of digital currency in Japan, the country’s major financial institutions—MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation—have joined forces to establish a formal collaborative council aimed at creating and jointly issuing a yen-backed crypto stablecoin by March 2027, coinciding with the conclusion of the fiscal year. This significant development signifies a step beyond mere experimentation, as the three banks will undertake a collective infrastructure initiative to introduce this cryptocurrency under a trust arrangement, where they will share specific roles as joint settlers, while a designated trust bank will act as the managing trustee.
Regulatory Framework
This initiative aligns with the Financial Services Agency (FSA) of Japan’s Payment Innovation Project, following a pilot launch in late 2025. During this pilot, the banks explored the feasibility of co-issuing a stablecoin through a legal framework, ultimately concluding the process was viable. Collectively, these banking giants hold assets exceeding $7 trillion, marking this effort as the largest institutional stablecoin initiative within Asia to date.
A closer look at Japan’s regulatory environment reveals that the stablecoin landscape was formally shaped in June 2023, with amendments to the Payment Services Act (PSA) that introduced a licensing structure for fiat-pegged stablecoins. Under this regulatory framework, the issuance is restricted to banks, trust banks, and registered fund transfer service providers. This regulatory moat enables the three major banks to operate securely within legal confines.
Innovation and Compliance
Since 2017, the FSA has supported innovation through its FinTech Proof-of-Concept Hub, which provided the necessary platform for the aforementioned pilot. Following the enactment of new PSA amendments in June 2026, additional regulations were imposed, including stringent travel rules for international transactions. Starting June 1, 2026, foreign-issued trust-type stablecoins will also need to meet FSA licensing, collateral management, and audit standards to operate as electronic payment instruments in Japan. Specific reserve rules stipulate that stablecoin issuers can invest up to half of their reserves in short-term Japanese government bonds (JGBs), ensuring that the expected megabank stablecoin will be fully safeguarded by cash and bonds in trust, in line with the FSA’s requirements for asset segregation and guarantee of value.
Recent Developments
In the context of Japan’s evolving stablecoin market, recent developments since the legalization of stablecoins have led to swift advancements. The first legally recognized yen-denominated stablecoin, known as JPYC, was launched in October 2025 by JPYC Inc., and gained regulatory alignment akin to established payment platforms such as PayPay and Rakuten Pay by April 2026, indicating its mainstream acceptance. SBI Holdings, in collaboration with Startale Group, introduced JPYSC in February 2026, designed for institutional and international transactions. In addition, the Japan Blockchain Foundation unveiled EJPY in May 2026, set to be issued on both the Japan Open Chain and Ethereum platforms.
Global Context
On a global scale, other financial entities are also making strides, with USDC being the first dollar-pegged stablecoin to receive approval in Japan in March 2025, while Ripple and SBI Holdings have plans to introduce RLUSD.
Conclusion
While technological aspects are crucial, what primarily distinguishes the megabank’s co-issuance model lies in its regulatory endorsement. Unlike JPYC and JPYSC, which are categorized as compliant offerings, a stablecoin resulting from the collaboration of Japan’s three largest banking institutions carries heightened institutional credibility and the potential for significant settlement volumes, reshaping the trajectory of Japan’s digital currency landscape.
