The Japanese government has taken a decisive step that redefines the future of digital assets in the world’s third-largest economy. On 10 April, a draft amendment to the Financial Instruments and Exchange Act (FIEA) was approved, reclassifying cryptocurrencies from mere payment mechanisms to full-fledged financial instruments, on a par with shares and bonds.
This is no minor adjustment; it is a legal paradigm shift which, if ratified by the Japanese Diet, will come into force in the 2027 financial year, laying the foundations for the sector’s widespread institutionalisation.
Key Reform Metrics
2027: Year of entry into force
20%: Proposed flat rate of income tax
13 million+: Cryptocurrency accounts in Japan
¥5 trillion+: Deposits on exchanges
From a payment method to a financial asset
Until now, crypto-assets in Japan have been regulated under the Payment Services Act, which restricted their perception and use to that of an alternative payment system. The new reform integrates them into the heart of the capital markets. This transition reflects a global shift in the interpretation of digital assets: they are no longer viewed as an external disruptive technology, but as integral components of the financial infrastructure.
Japan’s approach is in line with a global trend:
United States: Integration through ETFs and legislative frameworks such as the GENIUS and Clarity bills.
Europe: Unified regulation through the MiCA (Markets in Crypto-Assets) framework.
Asia: A coordinated move towards full financial integration, led by Japan.
Provisiones clave y reforma fiscal: un doble impulso
The amendment introduces securities-level regulation, designed to eliminate regulatory arbitrage and build institutional confidence. The most notable measures include:
-
- An explicit ban on insider trading in crypto-asset markets.
- Mandatory annual disclosures for cryptocurrency issuers.
- A drastic tightening of penalties: up to 10 years’ imprisonment for unregistered operators (compared to the previous 3 years) and fines of up to 10 million yen.
In parallel, a tax reform is being considered that could be as transformative as the legal reclassification itself.
Comparison of the Tax Burden on Cryptoassets
Current: 55%
Proposed: 20%The proposal aims to reduce the top progressive tax rate of 55% to a flat rate of 20%, bringing it into line with that for shares.
High taxation has historically been a barrier to retail and institutional investment. Reducing this friction could unlock a significant amount of dormant capital in the Japanese market.
Timeline of Crypto Regulation in Japan
- 2014: The Collapse of Mt. Gox
The hack of the Tokyo-based exchange highlights the urgent need for regulation and consumer protection.
- 2017: Payment Services Act
Japan becomes one of the first countries to legally recognise Bitcoin as a method of payment and establishes a licensing framework for exchanges.
- 2018–2019: Post-Coincheck Crackdown
Following the Coincheck hack, the Financial Services Agency (FSA) tightens supervision and requirements for exchanges.
- 2024: Proposed Amendment to the FIEA
The government approves the draft bill to reclassify cryptocurrencies as financial instruments, marking the beginning of the era of institutionalisation.
Why this is a structural shift: the gateway to institutionalisation
Legal reclassification is the key that unlocks the door to large-scale institutional investment. Once crypto-assets are treated as shares or bonds, they become eligible for:
- The creation of cryptocurrency-linked ETFs.
- The development of institutional-grade custody solutions.
- Capital allocations by pension and retirement funds.
- Direct integration into traditional portfolio management.
This move comes against a backdrop of coordinated regulatory momentum in Asia, with Hong Kong issuing licences for stablecoins and South Korea making progress on its Framework Act on Digital Assets. Asia is not merely regulating; it is positioning itself as a structured and innovation-friendly environment.

Conclusion for investors
From a legal perspective, this reform confirms that crypto-assets are not remaining on the fringes of the system, but are being absorbed into it and, in the process, transforming it. Japan is not merely regulating cryptocurrencies; it is expanding the very definition of what constitutes a financial instrument.
Key Points for Investors
▶ Window of Opportunity: Implementation in 2027 creates a multi-year timeframe for strategic positioning.
▶ Institutional Flows: A gradual increase in institutional capital in the Japanese market is expected as the implementation date approaches.
▶ Market Development: Market infrastructure (custody, derivatives, etc.) will be developed prior to the law coming into force.
▶ Assets to Watch: Assets with a strong presence in Japan, such as XRP through its partnership with SBI Holdings, could benefit directly.
The signal is clear: cryptocurrencies are moving from the periphery to the heart of the global financial system, not as an alternative, but as a new layer integrated into the existing structure.
