Japan has built the world's most stringent regulatory framework for stablecoins, with the milestone launch of JPYC Co.'s first fully regulated yen-pegged stablecoin in October 2025. The Financial Services Agency (FSA) amended the Payment Services Act (PSA) to permit only three types of licensed local entities—banks, fund transfer service providers, and trust companies—to issue what it calls "digital-money type stablecoins."
Strict Issuance and Reserve Requirements
Bank-issued stablecoins are treated as deposits under Japan's existing deposit insurance system. Fund transfer service providers must back their tokens with cash deposits, bank guarantees, or low-risk assets such as Japanese government bonds (JGBs). Trust companies hold all trust assets as bank deposits, with a post-2025 provision allowing up to 50% in low-risk short-term instruments. JPYC obtained a fund transfer service provider license in August 2025, launching its yen stablecoin on Avalanche, Ethereum, and Polygon with 1:1 yen reserves, zero transaction fees, and revenue generated from JGB yield. The company targets 10 trillion yen in circulation within three years and 60 trillion yen within five years, focusing on remittances, payments, and cross-border Web3 settlements.
Limited Access for Dollar Stablecoins
The framework effectively blocks USDT and USDC from mainstream Japanese access. Foreign issuers must meet the same user protection and AML standards as local entities, a hurdle few overcome. Japanese exchanges have long avoided listing USD stablecoins; USDT has been virtually untradable since early 2026. USDC has limited regulated access through SBI VC Trade following Circle's partnership with SBI Holdings, but retail availability remains narrow. The total market cap of JPY stablecoins stands at approximately $36.6 million as of early 2026—modest globally but growing in institutional and cross-border payment segments.
Major Banks Enter the Fray
Japan's three megabanks—MUFG, SMBC, and Mizuho—are developing yen stablecoins via the Progmat platform under joint proof-of-concept programs. SBI Holdings plans to launch a yen stablecoin in Q2 2026. Intermediaries must register as Electronic Payment Instrument Exchange Service Providers, hold at least 95% of customer crypto assets in cold storage, segregate user funds, comply with FATF Travel Rule requirements, and enter contractual liability-sharing agreements with issuers.
Regulatory Evolution and Logic
The 2022 Terra/Luna collapse hardened Japan's existing caution into law, enshrining redemption at par as a foundational principle. The 2025 PSA Amendment Act introduced a lighter intermediary category for pure brokers, eased certain reserve rules for trust-type issuers, and created greater flexibility for cross-border handling. The FSA is also considering moving certain crypto assets from PSA oversight to the Financial Instruments and Exchange Act. Japan's early regulatory history—sparked by the 2014 Mt Gox collapse—led to the first PSA amendments for crypto in 2016, establishing exchange registration, user asset segregation, and AML compliance. The current system, while slow and favoring local issuers, ensures every yen-pegged token in circulation carries a redemption guarantee, a licensed issuer, segregated reserves, and FSA supervision.
