Japan’s three largest banks are moving toward a coordinated entry into the stablecoin market. According to reporting by Decrypt, MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking Corporation have established a council to develop the operational and legal frameworks needed for a jointly issued stablecoin, targeting a launch by the end of fiscal year 2026—roughly March 2027.
The initiative represents a significant moment for institutional adoption of digital payments in Japan. Rather than compete individually, the megabanks are pooling resources to navigate a complex regulatory environment and establish trust infrastructure at scale.
Three Banks, One Stablecoin
Under the proposed structure, the three institutions will act as joint settlors under a trust agreement, with a designated trust bank or similar entity serving as trustee. The arrangement allows them to share technical and compliance responsibilities while maintaining distinct roles in the stablecoin’s governance.
The banks tested this model through a pilot project launched in late 2025, which examined whether multiple institutions could jointly issue a stablecoin while meeting “regulatory and practical compliance” requirements. That experiment proved foundational—the council is now building on those findings to prepare for production launch.
Fitting Into Japan’s Regulatory Moment
Japan’s stablecoin environment shifted dramatically in 2023 when regulators clarified licensing requirements under amendments to the Payment Services Act. The framework permits only banks, registered money transfer agents, and trust companies to issue fiat-pegged stablecoins, creating a controlled but accessible pathway for institutional entry.
This regulatory clarity has triggered a wave of yen-backed stablecoin launches. JPYC Inc. became the first to go live in October 2025. SBI Holdings and Startale Group followed with JPYSC in February 2026, positioning it for institutional and cross-border settlement. The Japan Blockchain Foundation then announced EJPY, set to launch on both Japan Open Chain and Ethereum networks.
Dollar-pegged stablecoins have also arrived. USDC gained approval in March 2025 through SBI’s crypto exchange, while Ripple and SBI Holdings are developing RLUSD for the Japanese market.
Strategic Implications
The megabanks’ joint stablecoin sits within the FSA’s Payment Innovation Project, a specialized sandbox designed to accelerate blockchain-based payment infrastructure. This positioning signals tacit regulatory support—the banks are not operating at the edges of compliance but rather within a dedicated innovation framework established since 2017.
The move addresses a practical constraint: retail and institutional payment networks in Japan remain fragmented. A stablecoin backed by three systemically important institutions could serve as a neutral settlement layer across use cases—corporate treasury transfers, interbank clearing, or cross-border remittances—without favoring any single operator.
Internationally, this mirrors moves by central banking consortiums elsewhere. The difference is that Japan’s approach relies on private banking actors rather than central bank initiatives, delegating the technical and operational burden to commercial institutions operating under a clear regulatory mandate.
For the broader stablecoin market, Japan’s institutional momentum matters. It demonstrates that stablecoins can integrate into legacy financial systems when regulators provide certainty and incumbent players see strategic value. The March 2027 timeline will test whether three competing megabanks can sustain cooperation once the stablecoin goes live.
