Japan's stablecoin regime: trust-type tokens, the 2025 reform, and JPYC

Japan regulates stablecoins under the Payment Services Act, which since June 2023 has treated fiat-pegged tokens as “electronic payment instruments” that only banks, licensed funds transfer service providers, and trust companies may issue. It was one of the first comprehensive stablecoin frameworks in any major economy, and it is now entering its second phase: a 2025 reform of the reserve rules takes effect by 13 June 2026, and the first approved yen stablecoin, JPYC, launched in late 2025.

Japan’s regime rewards attention for a reason beyond its own market. It answered the core design questions years before the GENIUS Act or full MiCA enforcement, and it answered some of them differently. Where MiCA built an e-money category and the US built a federal issuer licence, Japan routed stablecoins through institutions it already trusted: banks, money transmitters, and trust companies.

Who may issue, and how

The Payment Services Act recognizes three issuance routes. Banks can issue tokens representing deposits. Funds transfer service providers, Japan’s money-transmitter category, can issue tokens against safeguarded funds; this is JPYC’s route. Trust companies issue the third and most distinctive form, the trust-type stablecoin, where backing assets are held in trust for holders and remain bankruptcy-remote from the issuer.

Issuance is only half the gate. Distributing, exchanging, or managing electronic payment instruments requires a separate registration as an electronic payment instruments exchange service provider, with anti-money-laundering, disclosure, and asset-segregation obligations. That split matters for foreign tokens: a stablecoin issued abroad does not need a Japanese issuer, but it reaches Japanese users only through a registered intermediary that takes on those duties.

The 2025 reform: reserves and intermediaries

The original trust-type rule was strict: 100% of backing assets in demand deposits, withdrawable at any time. Safe, but economically punishing, since reserves earned close to nothing and Japanese issuers watched dollar-stablecoin issuers fund themselves on Treasury yields.

The 2025 amendment, approved by cabinet in March 2025 and promulgated on 13 June 2025, loosens that within tight bounds. Trust-type issuers may invest up to 50% of backing assets in Japanese or US government bonds with a remaining maturity of three months or less, or in time deposits that allow early cancellation. The other half stays in demand deposits. The law must be in force within one year of promulgation, so by 13 June 2026; the Financial Services Agency published draft cabinet orders and ordinances for public comment on 16 December 2025, and has consulted on exactly which bonds qualify. The amendment also added a lighter-touch intermediary category for crypto-asset and stablecoin brokerage, part of a broader restructuring of who may stand between issuers and users.

The design logic is recognizably Japanese: give issuers workable economics, keep the maturity so short that reserve risk stays near zero, and phase everything through consultation.

The regime in practice: JPYC and what follows

For its first two years the framework had no domestic token to govern. That changed in 2025. JPYC Inc. registered as a funds transfer service provider in August 2025 and launched JPYC, the first approved yen stablecoin, in late 2025 on Ethereum, Avalanche, and Polygon, targeting payments, cross-border remittances, and corporate settlement. SBI Group has been reported by Nikkei to be preparing its own yen stablecoin, JPYSC. The pattern to watch is the same one playing out globally: first a specialist issuer proves the route, then the large financial groups follow with distribution the specialist cannot match.

What institutions should do

Three practical readings. First, yen-denominated token settlement now has a regulated instrument and more on the way, so corridors into Japan can be planned around licensed rails rather than workarounds. Second, the distribution gate is the binding constraint: whatever token a flow uses, the Japan leg runs through a registered exchange service provider, and counterparty diligence should start there. Third, Japan’s reserve rules, issuer categories, and thresholds differ in detail from MiCA’s, from the GENIUS Act’s, and from Hong Kong’s ordinance. The differences are small individually and structural in aggregate: an institution running Tokyo, Frankfurt, and New York corridors is running three incompatible stablecoin rulebooks.

Where Frame fits

Frame is the settlement layer for global finance: one integration to orchestrate payments at scale across fiat rails, stablecoins, and tokenized deposits, with compliance enforced on every transaction and settlement in seconds instead of days.

Japan makes the case for treating jurisdiction rules as routing policy. Frame is rail-neutral and coin-neutral within the stablecoin rail: a payment enters through one integration and Frame routes it across whichever rail and instrument the corridor, counterparty, and governing policy allow. The rulebook differences this page describes, which instruments may settle a Japanese leg, through which registered counterparties, become conditions Frame’s Rules Engine evaluates on every transaction before it settles; a transfer that cannot satisfy them does not settle. Banks, payment providers, exchanges, platforms, and enterprises get the same property: divergent regimes absorbed in policy, one integration underneath.
