Japan's parliament approved legislation on Wednesday that reclassifies bitcoin and other cryptocurrencies as financial assets, marking a major regulatory shift that aligns digital assets more closely with traditional financial markets such as stocks and bonds. The amendment passed by the Diet moves crypto out of the Payment Services Act, where it was treated as a means of settlement, and into the Financial Instruments and Exchange Act (FIEA), the same statute that governs traditional securities, according to a report from public broadcaster NHK cited by Bitcoin Magazine. The change takes effect within a year, targeting fiscal 2027, and was accompanied by formal approval of a separate plan to cut the top tax rate on crypto gains from 55% to a flat 20% starting in 2028.
From Payment Services Act to Financial Instruments Framework
The reclassification represents a fundamental rewiring of how Japan supervises the crypto asset class. Previously regulated under the Payment Services Act as a payment instrument, cryptocurrencies now fall under the FIEA, subjecting them to a single investor-protection standard that mirrors the regime applied to stocks, bonds, and investment trusts. Japan's cabinet first approved the measure as a draft amendment in April 2026, sending the bill to the Diet for debate, and Wednesday's vote marks final enactment into law, as reported by Bitcoin Magazine.
The legislative journey began with signals from the Financial Services Agency (FSA) in November 2025, when the Nikkei business daily reported the FSA planned to revise the FIEA to give crypto assets legal status as financial products, according to The Hindu. FSA materials dated April 2026 confirmed the proposal would move crypto-asset transaction rules from the Payment Services Act to the FIEA, treating crypto assets as financial products separate from securities while introducing disclosure rules, tighter exchange oversight, insider trading restrictions, and stronger penalties for unregistered operators, as detailed by Cointelegraph. The Lower House passed the bill in early June 2026, clearing the Committee on Financial Affairs on June 10 before the final plenary vote this week.
Stricter Rules: Insider Trading, Disclosure, and Surveillance
As financial instruments, crypto assets now fall under insider-trading rules that bar issuers, exchange operators, and other parties with access to non-public information from trading ahead of events such as token listings, delistings, or major technical incidents, according to Bitcoin Magazine. Exchanges face new disclosure obligations requiring platforms to publish data on each token's issuer, blockchain design, and volatility profile, a standard that mirrors reporting demands placed on securities firms. Regulators also gain broader market-surveillance authority over the sector, according to local reports cited by Bitcoin Magazine.
The FSA's proposed framework would require crypto-asset transaction business operators to publish information on the assets they handle, while issuers of certain assets would face disclosure requirements when conducting offerings or secondary distributions, as reported by Cointelegraph. The Nikkei previously reported that crypto assets would be put under insider trading restrictions prohibiting buying and selling based on undisclosed internal information, according to The Hindu.
Sharply Higher Penalties for Unregistered Operators
Penalties climb significantly under the new law. The maximum prison term for unregistered crypto operators rises from three years to 10, while the top fine increases from 3 million yen to 10 million yen (near $62,000), according to Bitcoin Magazine. The tougher enforcement signals a move to treat crypto misconduct with the same severity as securities fraud. The FSA had indicated the bill would introduce stronger penalties for unregistered operators as part of the broader framework shift, as noted by Cointelegraph.
Path to Spot Bitcoin ETFs and Tax Overhaul
The reclassification carries two consequences that reach beyond compliance. First, it opens a path for spot bitcoin exchange-traded funds. Because the FIEA governs the products that funds can hold, moving crypto under its umbrella removes a structural barrier that kept Japanese asset managers from launching regulated bitcoin ETFs, according to Bitcoin Magazine. Bloomberg reported that the shift could open the door to crypto-tracking ETFs in Japan, giving local investors a regulated route to digital asset exposure beyond crypto exchanges and listed companies with token holdings, as cited by Cointelegraph.
Second, it clears the way for a tax overhaul. Japan currently taxes crypto gains as miscellaneous income at rates that reach 55 percent, among the steepest treatment in any major market. Lawmakers approved a plan to cut the top rate to a flat 20 percent, a level that matches the tax on stock gains. The reduction, tied to the 2026 Tax Reform Outline, activates in 2028, according to Bitcoin Magazine. The proposed changes could lower the capital gains tax on crypto assets like Bitcoin (BTC) and Ether (ETH) from the current maximum of 55% to a 20% flat rate, in line with stocks and bonds, with the tax change expected to take effect in 2028, as reported by Cointelegraph.
What Happens Next: Implementation Timeline and Market Impact
The legislation takes effect within a year, targeting fiscal 2027 for the regulatory framework shift, while the tax reduction activates in 2028. The reforms arrive as Japan accelerates a broader Web3 push and as regulators weigh reserve requirements for exchanges that resemble the buffers held by securities firms. User accounts on Japanese exchanges have grown, and domestic crypto firms are positioning for a wider base of retail investors, according to Bitcoin Magazine. For an industry that has long viewed Japan as an early and cautious mover, the vote marks a decisive turn toward legitimacy, with the country that once served as a template for crypto regulation now aligning digital assets with its capital markets — a decision that could pressure other jurisdictions to follow.
