Japan to lower crypto tax to 20% and classify digital assets as financial products.

Japan is preparing one of the most significant transformations of its digital asset regulatory framework to date, with plans to reduce the crypto tax rate from a maximum of 55% to a flat 20% and to reclassify 105 cryptocurrencies as financial products under the country’s securities regulation system. The reform is expected to be submitted to the Diet during the 2026 legislative session.

The overhaul aims to revive Japan’s crypto sector, address long-standing investor concerns over taxation, and strengthen oversight following recent security incidents at domestic exchanges.

Massive tax cut to align crypto with traditional financial markets

Under the existing tax rule, crypto gains are categorized as miscellaneous income and subject to progressive tax rates that can reach 55% when national and local taxes are combined. This structure has pushed many Japanese investors to move assets to offshore exchanges or establish residency abroad.

The new reform replaces progressive taxation with a 20% flat rate, putting crypto in the same category as stocks and derivatives.

Local reports indicate that 105 designated cryptocurrencies — including Bitcoin and Ethereum — will be formally reclassified under the Financial Instruments and Exchange Act (FIEA). This reclassification introduces mandatory disclosure requirements and applies insider trading regulations previously limited to securities.

The proposal also includes loss carry-forward privileges, allowing investors to offset crypto losses against future gains, a benefit already available to stock market participants. Analysts say this feature alone could significantly improve investor participation during volatile market conditions.

Industry leaders have responded positively. Former Binance CEO Changpeng Zhao commented that Japan’s move is a step toward global competitiveness, even if the tax rate is still higher than in jurisdictions that do not tax crypto gains at all. He emphasized that the direction of change is what matters.

Tightened regulatory controls for consumer protection

Alongside the tax adjustment, Japan’s Financial Services Agency (FSA) plans to implement tougher disclosure requirements for crypto issuers. These will include:

• detailed explanation of blockchain mechanisms • risk disclosures based on volatility and liquidity • operational transparency for protocol development

The move aims to bring the same protection standards to crypto that already exist for equities and bonds.

The reforms further introduce full insider trading restrictions for the 105 classified cryptocurrencies. Individuals — including project insiders, exchange executives, and corporate partners — will face penalties for trading on confidential information.

Banks and insurance companies will be prohibited from selling cryptocurrencies to consumers directly, which the FSA says is necessary to reduce financial risk for retail buyers. However, their securities subsidiaries may distribute crypto, enabling institutional participation under stricter supervision.

Officials are also reviewing whether banking groups should be allowed to hold crypto exchange licenses — a proposal that could eventually integrate crypto deeper into traditional financial infrastructure while preserving risk controls.

Security oversight expands to infrastructure providers

The reform also seeks to address a long-standing blind spot in Japan’s regulatory coverage. While exchanges have been heavily regulated since the Coincheck hack in 2018, third-party infrastructure providers have operated with less scrutiny.

This approach is changing following the DMM Bitcoin breach, which caused losses of 48.2 billion yen and exposed vulnerabilities in wallet management and custody systems.

The FSA now plans to require registration and supervision of critical infrastructure vendors, including:

• custody providers • wallet management firms • transaction processing providers • key service operators supporting exchanges

Officials say extending oversight beyond exchange operators is necessary to ensure that every layer of the crypto ecosystem meets national security requirements.

Positioning Japan as a leader in balanced global crypto regulation

Japan was one of the first countries to regulate crypto after recognizing Bitcoin as legal property in 2017. However, high taxation and stringent investor restrictions later slowed adoption and drove capital offshore.

Analysts say the new reforms represent the most unified attempt to strengthen consumer protection while keeping the domestic crypto industry competitive.

If approved, the legislation could take effect late 2026 or early 2027, depending on the Diet’s timeline. Meanwhile, the Financial System Council will publish its formal report in December 2025, with tax discussions progressing in parallel.

Regional developments may also play a role. South Korea is preparing for its own 20% crypto tax rollout in January 2027, and financial observers note that Japan’s reform could influence regulatory models across Asia as markets compete for investor capital and tech talent.

Japan’s next phase will depend on how domestic institutions, investors, and global crypto firms respond once the bill enters the legislative process. For now, the country has made its direction clear: lighter taxes to encourage innovation, paired with stricter rules designed to protect market integrity.
