Japan’s 2026 Crypto Tax Revolution: Rates Cut to 20%, Delivering Dual Benefits for Institutions and Retail Investors

11/18/2025, 7:30:55 AM
Japan plans to reduce the cryptocurrency capital gains tax from 55% to 20% starting in 2026 and to include crypto assets under financial product regulations, which has triggered institutional entry and market structure upgrades.

Why has Japan’s encryption tax attracted attention?

Japan has long been a pioneer in global encryption regulation. The proposed tax reform, which significantly lowers tax rates and reshapes the regulatory framework, is seen as one of the most influential policies for the encryption industry in recent years. If the policy is implemented, Japan will transition from a high-tax country to a more competitive encryption market, potentially attracting new users and international capital.

From “Miscellaneous Income” to “Capital Gains”: A Significant Tax System Shift

Under the current system, cryptocurrency gains are classified as “miscellaneous income,” subject to a progressive tax rate of up to 55%. The new bill plans to change this to “capital gains,” uniformly distinguishing it with a fixed tax rate of 20%, consistent with stocks and ETFs, significantly reducing the tax burden.

This shift has reduced tax complexity and made high-income or active traders more willing to return to the Japanese market.

Key policy points: 20% tax rate, 105 types of assets + compliance enhancement

The latest plan includes three core elements:

  • The unified tax rate is 20%, significantly reducing the burden on investors.
  • 105 mainstream encryption assets have been incorporated into regulation, establishing them as financial products.
  • Strengthen compliance mechanisms and information disclosure, including risk warnings, explanations of the issuer’s background, technical structure descriptions, etc.

Japan is also considering the introduction of a loss carryforward mechanism that would allow investors to use past investment losses to offset future gains, increasing the flexibility of the tax system.

The far-reaching significance for market participants

individual investors

  • The decrease in tax burden brings stronger trading momentum.
  • Market volatility may increase, leading to more arbitrage and short-term opportunities.

institutional investors

  • As encryption assets are incorporated into the traditional financial regulatory system, banks, brokers, and other institutions will be able to participate directly.
  • The decrease in compliance barriers may lead to the emergence of more structured products (such as ETFs, options, and staking products).

trading platform

  • A more standardized regulatory framework increases market confidence.
  • Disclosure obligations are raised, prompting the platform to enhance security and transparency.

Enhanced regulatory transparency: Information disclosure and insider trading rules

The new regulations require exchanges to provide more comprehensive information disclosure for encryption projects, including technical security, volatility, and the background of the issuer. At the same time, the FSA will establish a regulatory system for insider trading in the encryption field, prohibiting trading activities that involve undisclosed significant information, making the market more transparent and fair.

Potential Risks and Challenges

Despite the clear direction of reform, challenges still exist:

  • The bill needs to be reviewed by Congress, and there is uncertainty regarding its passage and implementation.
  • There may be significant market fluctuations before and after the policy is implemented.
  • New regulatory requirements may increase the operating costs of exchanges.
  • Although the tax rate has been reduced to 20%, it is still not as attractive as some tax-exempt or low-tax areas.

Outlook on the future landscape of the Japanese encryption market

With the simultaneous advancement of tax reform and regulation, Japan may become one of the most stable and transparent encryption asset markets in the world:

  • Compliance financial products may grow rapidly.
  • More large institutions and global capital are entering the Japanese market.
  • The overall trading volume and the number of users are expected to increase.
  • Japan may become an important bridge connecting Asia and global encryption finance.

In the long term, this reform is not only a tax rate adjustment but also the important beginning of Japan’s encryption financial era.
