Japan Treats Stablecoins Like Cash: FSA Drops Per-Transfer Tax Filings for Trust-Based Tokens

While the world still argues over whether stablecoins are securities or money, Japan has moved first: freeing trust-based stablecoins from per-transfer tax filing, explicitly treating them as payment tools rather than investment assets.

On August 31, Japan’s Financial Services Agency (FSA) tucked a modest-sounding request into its fiscal 2027 tax reform proposals: exempt trust-based stablecoins from the per-transfer tax filing obligation triggered whenever a beneficiary changes. Under the current Inheritance Tax Act, a trustee must submit beneficiary statements to tax authorities each time a trust beneficiary changes. For a stablecoin, every on-chain transfer changes the beneficiary. A rule written for family trusts, applied to a high-frequency payment instrument, turns into a product-design constraint that cannot be met at scale.

The FSA placed the request under “promotion of financial innovation,” and its rationale is blunt: trustees cannot identify each holder by name or track every change in real time across an active payment network. This is a blanket exemption, not a lower threshold or a simplified process. If the government and ruling coalition adopt it in the year-end tax outline, it could take effect as early as April 1, 2027.

1. Why It Matters: A Rule Written for Family Trusts Chokes a Payment Instrument

Japan’s 2022 legal amendment created a lawful path for stablecoin issuance, allowing three types of issuers: licensed banks, trust companies, and registered fund-transfer service providers. Trust-based stablecoins fall under “specified trust beneficiary rights,” the third category of electronic payment instrument, with reserves held in segregated trust accounts and holders enjoying a stronger legal claim on the underlying trust assets. SBI Shinsei Trust Bank’s JPYSC, launched in June 2026 as Japan’s first trust-based yen stablecoin, is the working example of this architecture.

Yet the protective machinery of trust law also brings a side effect. Traditional trusts have a relatively stable set of identifiable beneficiaries, so per-change filing is manageable; a stablecoin can generate massive transfer volumes in a single day, and trustees can neither match addresses to real holders nor track each change. The commercial consequence is concrete: while the filing burden stands, trust-based stablecoins are workable only for institutional settlement between known counterparties and unusable for retail circulation, effectively sealing off the payment use cases trust banks want to build.

2. The State of Play: Institutional Infrastructure Is Nearly Complete, Tax Is the Last Piece

Over the past year, Japan has assembled almost the entire institutional stack for stablecoins. On August 7, the FSA opened a dedicated Cryptocurrency and Stablecoin Division. On August 24, it removed the JPY 1 million per-transaction cap on second-category fund-transfer service providers, making institutional B2B settlement, cross-border payments, and treasury operations viable. On July 15, the Diet passed the Financial Instruments and Exchange Act revision that reclassified 105 crypto assets as financial instruments, while deliberately leaving stablecoins and DeFi under the Payment Services Act for later, dedicated treatment.

Outwardly, the FSA has cleared Ripple’s RLUSD for distribution through SBI VC Trade and made Circle’s USDC available via the same licensed channel since March 2025. The three largest megabanks are jointly building on the Progmat platform, targeting JPY 1 trillion in B2B transactions by 2028. From issuance to distribution to settlement, Japan’s stablecoin rails are now connected; only the tax code lags behind.

That is the backdrop for the Blockchain Promotion Council (BCCC) tax committee kicking off on September 15. The urgency is grounded in real business: logistics firm AZ-COM Maruwa Holdings already pays roughly 2,300 drivers in JPYC, Lawson is piloting stablecoin payments at checkout, and none of it yet has a matching income-tax framework.

3. Deep Analysis: Three Signals Behind the Tax Reform

4. Investment View and Conclusion

Japan’s posture toward stablecoins has moved from “licensing and oversight” to “paving the way for payments.” The tax reform is a policy signal, not an immediate catalyst; the real variables are the BCCC tax committee launching on September 15 and whether the year-end tax outline adopts the measure. For practitioners, two directions are worth watching: the penetration of trust-based stablecoins into institutional settlement and tokenized securities, and how the FSA’s openness to foreign-issued trust tokens reshapes the retail competition for RLUSD, USDC, and other overseas issuers in Japan.

While the rest of the world debates whether a stablecoin is a security or a currency, Japan has used a single tax exemption to answer the question. It is choosing to turn stablecoins into cash. That may be the most underrated move in digital-asset regulation this year.
