The Japanese yen went on-chain in October 2025, when the country's first regulated yen-pegged stablecoin launched. Three of its biggest banks have since joined the race, the Finance Minister has taken the stage at a digital currency summit, and tax law is moving in the same direction. Japan is past the stage of talking about this.

From Blueprint to Reality: Japan's Stablecoin Moment

2025 will go down as year zero for Japan's stablecoin market. A stablecoin is a digital currency pegged 1:1 to a traditional currency, here the Japanese yen. Without Bitcoin's price swings, it can be used directly for payments and transfers.

First out was JPYC Inc., a fintech that secured registration as a licensed fund transfer service provider from Japan's Financial Services Agency (FSA) in August 2025. On October 27 it launched the first yen-backed stablecoin under Japan's revised Payment Services Act, classified legally as an "electronic payment instrument," a category distinct from cryptocurrency. About seven months in, cumulative issuance had passed ¥3 billion and account openings had reached 19,000 (both as of May 30, 2026). Total transaction volume has topped ¥35 billion, and circulating supply crossed one billion JPYC in June 2026.

JPYC runs on Ethereum, Polygon, Avalanche and Kaia, with reserves backed 80% by Japanese government bonds and 20% by cash deposits. Issuance and redemption are free, and identity verification takes as little as a minute using Japan's My Number Card digital ID.

Megabanks Join the Race: A Joint Stablecoin for Corporate Japan

Shortly after JPYC's launch, Japan's three largest banks, Mitsubishi UFJ (MUFG), Sumitomo Mitsui (SMBC) and Mizuho, announced plans to jointly issue a yen-pegged stablecoin. In November 2025 the FSA approved the initiative as the first project under its newly created Payment Innovation Project (PIP), a sandbox built for blockchain-based payment work. Mitsubishi Corporation, MUFG Trust & Banking and Progmat are also taking part in the pilot.

The design turns on the trust structure. The three banks act as joint trust settlors and a trust bank serves as trustee and issuer, so the reserves sit behind the trust's bankruptcy-remote protection. That is a different form of asset protection from JPYC or USDC, where the issuer holds the backing itself. The technical base is Progmat, a digital asset infrastructure platform developed within the MUFG group, and the three banks plan a single shared brand. Unlike JPYC's ¥1 million ($6,700) per-transaction cap as a Type II fund transfer operator, the trust type carries no transfer limit, which makes it viable for large corporate settlements.

The first use case is internal and external payments at Mitsubishi Corporation, starting with cross-border settlement between its Japanese and overseas offices, and extending to dividend transfers, acquisition payments and customer settlements.

The banks' entry is also defensive. If stablecoins take hold, deposits shrink and lending capacity shrinks with them. The International Monetary Fund flagged the risk in a December 2025 report, warning that stablecoin growth could disintermediate small deposits and squeeze bank margins.

SBI's Two-Currency Strategy

SBI Holdings is running a dual-currency strategy. Its subsidiary SBI VC Trade became Japan's first registered Electronic Payment Instruments Exchange Service Provider in March 2025, starting with Circle's USDC. SBI has also signed a basic agreement with Ripple Labs to bring the dollar-backed RLUSD to Japan, targeting fiscal 2026.

On the yen side, SBI has a basic agreement with Sumitomo Mitsui Banking Corporation and is working toward integration with its securities and banking arms. To get around the ¥1 million transfer cap that applies to foreign-issued stablecoins, it plans to use Shinsei Trust Bank as the domestic issuing entity.

Government Signals: Finance Minister Takes the Stage

Japan's government commitment goes beyond regulation. Finance Minister Satsuki Katayama, who also oversees the FSA, delivered the opening address at MoneyX, a next-generation finance conference held in Tokyo on February 27, 2026. The event was co-organized by JPYC, Progmat, SBI Holdings and CoinPost, with backing from the Ministry of Economy, Trade and Industry and several financial industry associations.

That reflects a broader policy shift. Japan is moving to reclassify crypto assets from payment instruments under the Payment Services Act to financial products under the Financial Instruments and Exchange Act (FIEA), the same law that governs stocks and bonds. Taxation is set to move with it, from miscellaneous income rates as high as 55% to a flat 20.315%, the rate applied to equities. Katayama used the phrase "digital year one" at the Tokyo Stock Exchange's opening ceremony in January 2026, and the plan is to move regulation, tax and infrastructure together.

Global Regulation Comparison: Where Japan Stands

Japan: Revised Payment Services Act (Effective June 2023)

Japan was among the first major economies to put a comprehensive legal framework in place. The law defines stablecoins as electronic payment instruments, restricts issuance to banks, fund transfer operators and trust companies, and mandates full backing with yen deposits and government bonds held in segregated accounts. Algorithmic stablecoins are prohibited, and redemption at face value is guaranteed.

United States: GENIUS Act (Signed July 2025)

The GENIUS Act (Guiding and Establishing National Innovation for US Stablecoins) is America's first federal stablecoin law. It requires 1:1 reserve backing, bans yield-bearing stablecoins, and creates a dual oversight system: federal regulation for large issuers (over $10 billion in circulation) and state-level supervision for smaller ones. Notably, it classifies compliant stablecoins as neither securities nor commodities, removing them from SEC and CFTC jurisdiction.

European Union: MiCA Regulation (Fully Effective June 2024)

The EU's Markets in Crypto-Assets (MiCA) regulation is the world's most comprehensive framework, covering all crypto assets. Stablecoins are classified as "e-money tokens" (EMTs) or "asset-referenced tokens" (ARTs). Issuers must hold 30-60% of reserves in EU banks and "graduate" to supervision by the European Banking Authority (EBA) once they reach certain size thresholds.

Key Differences

All three frameworks share core principles: 1:1 reserve requirements, par-value redemption rights, AML/KYC obligations, and mandatory licensing. But important differences emerge. Japan moved first, with its framework operational two years before the GENIUS Act. The US approach is more conservative than MiCA in some ways, requiring stablecoin operations to be ring-fenced from core banking activities. MiCA offers the broadest coverage but faces implementation challenges across 27 member states with varying interpretations.

Japan's sequence, legislate first and then run experiments with the regulator alongside, differs from America's enforcement-first history and the EU's broad but slow rollout. The FSA's Payment Innovation Project is the practical expression of it: the regulator helps banks and startups work out compliance rather than waiting for them to guess.

Challenges and Outlook

Hurdles remain. JPYC's ¥3 billion (about $20 million) in cumulative issuance is a rounding error next to USDC's daily trading volume. The ¥1 million per-transaction cap for Type II fund transfer operators limits corporate adoption. And for a long stretch, SBI VC Trade was the only registered electronic payment instruments exchange provider.

There is also the adoption question. In a country where PayPay and Suica already work, why would an ordinary consumer switch? Industry consensus is that expanding the places you can spend matters more right now than expanding the number of holders.

The candidate use cases are concrete: cross-border payments, delivery-versus-payment in securities settlement, payments executed by AI agents, and a yen-denominated option for inbound tourists. In February 2026 the FSA adopted a blockchain securities-settlement pilot run by major brokerages and megabanks as a PIP-supported project, which moves the DvP case from discussion into testing.

JPYC for retail, the megabanks for corporate settlement, SBI for international connectivity. Whether those three layers mesh is the question 2026 answers.

Japan's yen-backed stablecoins are moving from experiment to reality, with individual consumers, mega-corporations, and international finance all being drawn into the ecosystem. How about in your country, are stablecoins or central bank digital currencies (CBDCs) part of daily life yet? Do you see yourself paying for things with digital currency anytime soon? We'd love to hear your perspective.

Update: In June 2026 the three megabanks agreed to set up a working council for joint issuance and said they are targeting live transactions during fiscal 2026. On the trust-type side, SBI and the Shinsei group have set a fiscal-2026 first-quarter launch for JPYSC, and Japan Blockchain Infrastructure plans EJPY within fiscal 2026, forming a market split between fund-transfer-type and trust-type issuers alongside JPYC. The bill moving crypto assets to the FIEA was approved by cabinet on April 10, 2026 and passed the lower house on June 11; if enacted, it is expected to take effect in fiscal 2027, with the shift to separate taxation following the same track.
