Japan Slashes Crypto Tax to 20% in Historic Reform—But There’s a Catch

December 29, 2025 Nxtgen Virtue

Tokyo — In a landmark shift that could reshape Asia’s digital asset landscape, Japan has unveiled plans to dramatically reduce cryptocurrency taxation from a punishing 55% to a flat 20% rate, putting digital assets on equal footing with traditional equities for the first time.

The reform, outlined in the government’s 2026 tax blueprint released this week, marks a decisive pivot toward embracing crypto investment as Japan seeks to reclaim its position as a regional fintech leader.

A Game-Changer for Japanese Investors

Under current law, cryptocurrency profits fall under “miscellaneous income,” subject to Japan’s progressive tax system with rates climbing as high as 55%. This severe tax burden has long discouraged domestic trading and pushed Japanese investors toward overseas platforms.

The new framework reclassifies qualifying cryptocurrencies under a separate taxation structure with a fixed 20% levy—matching the treatment of stocks and investment trusts. The change is expected to take effect in 2026.

“With cryptocurrencies now subject to the revised Financial Instruments and Exchange Act, various measures to protect investors are being put in place, making it easier for many people to accept cryptocurrencies,” said Kimihiro Mine, CEO of fintech firm finoject and a leading voice on crypto taxation policy.

The Fine Print: Not All Cryptos Qualify

However, the tax reduction comes with important limitations. According to reporting by Nikkei, the reform applies exclusively to “specified crypto assets”—digital currencies handled by businesses registered under Japan’s Financial Instruments Business Operator Registry.

While major cryptocurrencies like Bitcoin and Ethereum are widely expected to receive “specified” status, the exact criteria and business requirements remain undefined. This ambiguity has left smaller altcoins and decentralized tokens in regulatory limbo.

Industry observers caution that the restriction could create a two-tiered market, with registered assets enjoying favorable tax treatment while others remain subject to the higher miscellaneous income rates.

Additional Benefits: Loss Carryforward and Investment Products

The reform package includes other investor-friendly provisions. A new three-year loss carryforward system will allow traders to offset future gains with previous losses, providing a safety net similar to that enjoyed by stock investors.

Perhaps most significantly, the revised framework will permit investment trusts incorporating cryptocurrencies—opening the door for institutional-grade crypto products. Japan has already taken steps in this direction, launching its first XRP exchange-traded fund (ETF) earlier this year, with plans for two additional crypto ETFs in the pipeline.

Positioning Japan as a Crypto Hub

The tax overhaul represents Japan’s most aggressive attempt yet to foster a vibrant domestic crypto market. For years, the country’s harsh tax regime has been cited as a primary reason why Japanese crypto activity pales in comparison to neighbors like South Korea and Singapore.

By aligning crypto taxation with traditional securities, Japanese policymakers are betting they can attract both retail and institutional capital back to domestic exchanges—while maintaining the stringent investor protections that have defined the country’s regulatory approach since the 2018 Coincheck hack.

As implementation details emerge over the coming months, the crypto industry will be watching closely to see which assets make the cut for “specified” status—and whether Japan’s bold experiment can truly level the playing field between old finance and new.
