Japan is executing the most consequential crypto regulatory pivot in Asia. The country that once taxed crypto gains at up to 55%, which drove liquidity offshore and cemented its reputation as a hostile jurisdiction for active traders, has now published new rules allowing foreign trust-type stablecoins to operate as regulated payment instruments starting June 1. It’s one visible piece of a much larger regulatory reform package taking shape from Tokyo.
Even last year, Japan’s National Tax Authority currently treats most crypto gains as “miscellaneous income” in a category subject to progressive rates that reach 55% at the top bracket. This explains why high-frequency traders, market makers, and Web3 startups have been migrating to Singapore and Dubai for years.
The proposed reform targets a flat 20% settlement tax, identical to the rate applied to equities and investment trusts under Japan’s Financial Instruments and Exchange Act (FIEA). The Japan Cryptoasset Business Association has been explicit in its position papers: competing Asian hubs tax retail crypto gains at 0–15%.

But the tax rate is only half the mechanism. The other half is legal reclassification. For a 20% rate to apply, crypto assets, particularly large-cap tokens like BTC and ETH, must be reclassified as financial instruments under the FIEA rather than sitting in the Payment Services Act’s looser framework. This carries a downstream consequence: it makes spot and derivative ETFs legally viable, managed by licensed financial instruments business operators.
The Bitcoin ETF Gateway: Which Institutions Are Already Positioned
The US precedent is the reference point every Japanese regulator is working from. U.S.-listed Bitcoin ETFs, approved by the SEC in January 2024, drew billions in institutional inflows within weeks of launch, validating a market structure that Japan has been unable to replicate under its existing legal framework.
European UCITS structures have followed a parallel path, with major asset managers building regulated crypto exposure products under MiCA-adjacent frameworks.
Japan’s institutional groundwork is further along, as Nomura’s digital-asset subsidiary Laser Digital and Mitsubishi UFJ Trust and Banking have both been piloting tokenized securities and fund units under existing FIEA frameworks. They have publicly argued that similar structures could be applied to spot Bitcoin and Ethereum products once classification and tax rules align.
Also happening this week, SBI Holdings filed for crypto ETF products in Japan, positioning itself at the front of what would become a structurally new domestic market.
The FSA’s June 1 stablecoin framework is part of the same institutional logic. SBI VC Trade is actively exploring licensed services involving USDC under the new rules, which reclassify qualifying foreign trust-type stablecoins as Electronic Payment Instruments under the Payment Services Act. This regulated stablecoin rails, licensed intermediaries, and equivalence standards for foreign issuers, the settlement layer that a functional ETF market needs.

Japan vs. the Global Crypto Regulatory Race: Where the FSA Stands Against the CLARITY Act and MiCA
Regulatory reform is not happening in isolation. Across the Pacific, the US Senate Banking Committee advanced the CLARITY Act, which defines jurisdictional boundaries between the SEC and CFTC. Galaxy Digital’s head of firmwide research, Alex Thorn, puts the probability of the CLARITY Act becoming law in 2026 at 65% to 75%.
The EU’s MiCA framework is already live. Hong Kong launched spot Bitcoin and Ethereum ETFs ahead of Japan. Singapore maintains 0% capital gains on crypto. Japan’s advantage is not speed; it is depth, with Japan’s domestic savings pool measured in trillions.
Latham & Watkins analysts have characterized Japan’s direction as convergence toward a “rules-first but innovation-tolerant” posture, closer to MiCA in philosophy than to the US’s ongoing jurisdictional battles.
