Japan Reclassifies Crypto Assets Under Financial Instruments Act

Japan’s cabinet approved a landmark bill on April 10, 2026, to reclassify cryptocurrencies (crypto assets) as financial instruments under the Financial Instruments and Exchange Act (FIEA) for the first time.

The move shifts oversight from the Funds Settlement Act, which treated them mainly as payment tools, to the stricter FIEA framework that governs stocks and bonds. This reflects crypto’s evolution into a popular investment vehicle.

Key provisions include a ban on insider trading using non-public material information and mandatory annual disclosures by crypto issuers to boost transparency. Crypto exchange operators will be renamed “crypto asset trading operators.”

Penalties will be significantly strengthened for investor protection: the maximum prison term for unregistered sales will rise from three to 10 years, while fines will increase from ¥3 million to ¥10 million.

Japan’s history in crypto regulations

Japan has long been a pioneer in crypto regulation. The Mt. Gox collapse in 2014, which resulted in the loss of hundreds of millions of dollars in Bitcoin, exposed critical vulnerabilities and prompted early action. 

In response, Japan amended the PSA in 2016, with regulations taking effect in April 2017. This made Japan one of the first major economies to formally recognize Bitcoin as legal tender and establish a registration system for crypto asset exchange service providers. 

Further enhancements came in 2019 through amendments to both the PSA and FIEA. These introduced stronger customer protections, rules on crypto derivatives, regulations for security tokens (treated as collective investment schemes), and prohibitions on market manipulation and unfair trading practices. 

In 2022–2023, Japan implemented the “Travel Rule” for anti-money laundering compliance and introduced a dedicated framework for stablecoins as electronic payment instruments, restricting issuance primarily to banks and licensed entities.

Despite these measures, rapid market growth—driven by retail investors (with many holding small amounts under 100,000 yen)—highlighted gaps. Crypto was still largely viewed through a payments lens, leaving investment-specific risks like insider trading unaddressed under full securities-style rules. 

Discussions intensified in 2025 via the Financial Services Agency’s (FSA) working groups, culminating in proposals to align regulation with crypto’s dominant use case as an asset class. 

Key provisions of the 2026 bill

The latest amendments ban insider trading based on non-public material information, such as upcoming listings, delistings, or issuer financial issues. Crypto issuers must provide mandatory annual disclosures, including details on technology, volatility, and governance, to enhance transparency for the roughly 105 tokens currently listed on licensed Japanese platforms.

Under new terms, crypto exchange operators will be renamed “crypto asset trading operators,” reflecting their expanded role. Penalties for violations, particularly unregistered sales, will be significantly toughened: the maximum prison term rises from 3 years to 10 years, and fines increase from ¥3 million to ¥10 million. 

These measures empower the Securities and Exchange Surveillance Commission (SESC) with stronger enforcement tools, including surcharges tied to illicit gains. 

Broader implications

Finance officials, including comments from Minister Katsuyuki Katayama, emphasized that the reforms aim to promote market fairness, transparency, and the supply of growth funds amid evolving capital markets. 

By treating crypto like traditional financial products, Japan seeks to reduce risks of misconduct while fostering a safer, more mature ecosystem. This move also paves the way for complementary tax reforms, potentially introducing a flatter 20% capital gains rate (down from progressive rates up to 55%) for qualifying crypto transactions, aligning it with equities.

The overhaul positions Japan competitively among G7 nations, balancing innovation with robust investor protection. It addresses rising retail participation and global concerns over market abuse, while encouraging institutional involvement and potential new products like crypto-linked ETFs.

This regulatory milestone builds on nearly a decade of progressive policymaking. It signals Japan’s commitment to integrating digital assets into its financial system responsibly, potentially boosting confidence and long-term growth in one of the world’s most regulated crypto markets.

If the bill passes the current Diet session, the changes are expected to take effect in fiscal 2027 (starting April 2027). Meanwhile, NFTs and certain stablecoins are likely to remain under the existing PSA regime.
