Japan is preparing one of its most significant digital-asset policy shifts to date, with the Financial Services Agency (FSA) moving toward a full reclassification of crypto assets such as Bitcoin and Ether. Under the plan, 105 cryptocurrencies would be treated as “financial products” beginning in early 2026, a change that would reshape investment incentives, tax policy, and legal oversight across the country’s rapidly expanding crypto market.
Flat 20% Tax Would Replace Today’s Punishing Rates
One of the biggest components of the proposal is a complete overhaul of how crypto gains are taxed.
Currently, profits fall under Japan’s progressive income bracket system, which can reach more than 55% for higher earners. The FSA is pushing to eliminate that model entirely and replace it with a single 20% capital-gains tax, mirroring the structure used for stock trading.
The agency’s goal is clear: reduce barriers that discourage domestic investors from participating in crypto markets and bring digital assets closer to traditional investment products.
Japan to Introduce First Insider-Trading Rules for Crypto
Alongside tax changes, the FSA is exploring a regulatory upgrade aimed at closing one of the industry’s most notorious gaps, the absence of insider-trading rules.
If approved, the Securities and Exchange Surveillance Commission (SESC) would gain full authority to investigate suspicious trading, enforce penalties, and restrict insiders from using non-public information related to exchanges, token listings, or project partnerships. The move would formally place crypto under the same legal expectations applied to securities markets, increasing accountability for both companies and individuals.
A Reclassification With Major Consequences
The upcoming shift would move cryptocurrencies out of the Payment Services Act, the framework that originally classified them as digital payment instruments, and into the Financial Instruments and Exchange Act (FIEA).
This reclassification positions Bitcoin, Ether and more than 100 other assets squarely inside Japan’s financial-product ecosystem, opening the door to stricter investor protections but also more favorable tax treatment.
Market Context: BTC Pulls Back, ETH Remains Mixed
The policy news arrives during a week when Bitcoin experienced a noticeable decline, reflecting global risk sentiment and tightening liquidity conditions. Ether’s market environment has been less uniform, with short-term performance influenced by broader macro signals and shifting expectations around upcoming U.S. economic data.
A Transformative Shift for Japan’s Crypto Landscape
If enacted on schedule, the FSA’s overhaul would dramatically change how digital assets are traded, taxed, and supervised. Lower taxes may spark renewed retail participation, while insider-trading rules and FIEA classification would push the industry closer to the regulatory standards of traditional finance.
Japan, one of the earliest adopters of digital-asset regulation, is now positioning itself to become one of the most structured and investor-friendly environments for crypto in Asia, provided the reforms move from proposal to law in 2026.
