SBI Group and Startale Launch Japan's First Trust-Based Yen Stablecoin JPYSC
Japanese financial conglomerate SBI Group and Singapore-based Startale Group launched JPYSC, Japan's first trust-based yen stablecoin, on June 24, 2026. The launch marks a significant step in Japan's regulated digital currency infrastructure.

The regulatory backdrop is unusually well-prepared by global standards. Japan enacted comprehensive stablecoin legislation in 2022, and the Financial Services Agency completed enforcement rules on June 13, 2026 — eleven days before the JPYSC launch. The FSA separately activated rules for qualified foreign stablecoins on June 1, 2026, according to Ledger Insights coverage of the FSA framework. That sequencing — rules finalised, then product launched — is atypical in crypto markets and reflects the deliberate pace at which Japan's payment-services regime was constructed.
Startale's role in the project is technical development and blockchain infrastructure. The Singapore-based firm raised $63 million in a Series A round in March 2026, with SBI contributing $50 million and Sony contributing $13 million, earmarked for JPYSC and a companion dollar stablecoin designated USDSC. CoinDesk's coverage of the Series A noted that the capital was explicitly allocated to building Japan's tokenized finance stack, with JPYSC as the anchor product. Startale has also referenced its proprietary Strium L1 blockchain and Sony's Soneium network as likely future deployment targets, though neither chain has been confirmed as a live JPYSC environment as of the launch date.
The intended use cases span institutional treasury management, cross-border settlement, AI agent micropayments, and tokenized real-world asset transactions. SBI Group has publicly framed JPYSC as foundational infrastructure for on-chain RWA markets rather than a retail payments product, a positioning consistent with the instrument's current distribution restriction to SBI VC Trade account holders. Public blockchain circulation and transfers to external wallets remain pending further regulatory and tax clarification from Japanese authorities — neither timeline nor conditions for that expansion have been disclosed.
Japan's stablecoin market is becoming competitive. JPYC launched under the Type II framework in October 2025, and a joint stablecoin initiative by Japan's three megabanks — MUFG, SMBC, and Mizuho — is targeting commercial transactions by March 2027, according to Crypto Briefing's analysis of the competitive landscape. JPYSC therefore enters a market where at least two other institutional-grade yen digital currency efforts are in progress, with the trust-bank classification and the absence of a transaction cap as its primary structural differentiators.
Several material details remain undisclosed. SBI and Startale have not published the initial issuance volume or any target circulation figure for JPYSC. The companies have not identified specific institutional counterparties that have committed to using the stablecoin for settlement or RWA transactions. The timeline for expanding JPYSC beyond SBI VC Trade to external wallets or alternative blockchains has not been set. The mechanics of JGB allocation within the reserve — including duration limits, concentration rules, or rebalancing triggers — have not been made public. The tax treatment of JPYSC transfers, which Japanese authorities have not yet clarified, remains an open variable that constrains the instrument's utility for retail and cross-border use.
What the June 24 launch concretely establishes is a live, trust-bank-issued yen stablecoin operating under Japan's Type III Electronic Payment Instrument classification, available to SBI VC Trade account holders on Ethereum. It does not establish a confirmed deployment on Strium or Soneium, a disclosed reserve volume, a named institutional client using JPYSC for settlement, or regulatory clearance for public blockchain circulation or external wallet transfers.
