Crypto Tax in Japan: Complete 2026 Guide
How is Crypto Taxed in Japan?
Japan taxes individual cryptocurrency gains as miscellaneous income (zōzei shotoku, 雑所得) under the Income Tax Act. This is one of the most expensive tax categories in the Japanese tax code. Crypto gains aggregate with salary, pension, and other income, taxed at the progressive national income tax rate (5% to 45%) plus a 10% local resident tax, reaching a combined marginal of approximately 55% at the highest bracket.
Critically, Japan does not apply preferential capital-gains treatment to crypto. Unlike listed equities (which receive a 20.315% flat treatment) or property (which has its own capital-gains regime), crypto is firmly in the highest-tax category. The National Tax Agency (NTA) has resisted industry pressure to reclassify crypto despite consistent lobbying since 2017.
For high earners, holding crypto as a Japanese tax resident can be more expensive than in most major economies. A US investor with $1M of crypto gains in California pays roughly 33% federal + 13.3% state ≈ 46%. A UK higher-rate taxpayer pays 24%. A Japanese top-bracket taxpayer pays 55%. This drives ongoing reform discussions but no enactment as of 2026.
Japan Crypto Tax Rates
Combined national income tax + local resident tax (10% flat):
| Income Bracket (¥) | National Income Tax | Combined Marginal |
|---|---|---|
| Up to 1,950,000 | 5% | ~15% |
| 1,950,001 – 3,300,000 | 10% | ~20% |
| 3,300,001 – 6,950,000 | 20% | ~30% |
| 6,950,001 – 9,000,000 | 23% | ~33% |
| 9,000,001 – 18,000,000 | 33% | ~43% |
| 18,000,001 – 40,000,000 | 40% | ~50% |
| 40,000,001+ | 45% | ~55% |
An additional 2.1% national reconstruction surcharge applies to the national income tax (extended through 2037). At the highest national rate of 45%, this adds ~0.945% to your marginal.

Crypto Tax for Specific Activities in Japan
Staking
Staking rewards are miscellaneous income at fair market value when received. The income amount becomes cost basis for the received coins, which then count toward subsequent disposal gain calculations.
Mining
Hobby mining is miscellaneous income at fair market value at receipt. Commercial mining is business income, with deductible expenses. The threshold is judgemental but generally requires structured commercial activity.
NFTs
NFTs fall within the misc-income regime when held by individuals. NFTs created by an artist and sold directly may be classified as business or royalty income.
DeFi
The NTA has not issued comprehensive DeFi guidance. Yield from DeFi protocols is generally treated as misc income at receipt; the underlying protocol interactions may each constitute taxable disposals depending on facts.
Crypto Salary
Crypto wages are employment income at JPY-equivalent at payment, subject to standard withholding by the employer.
Reform Watch
Japanese crypto industry associations — notably the JCBA (Japan Crypto Business Association) — have lobbied for years to reclassify cryptocurrency from miscellaneous income to a 20.315% flat capital-gains regime, mirroring listed equities. The Liberal Democratic Party\'s tax committee has studied the proposal repeatedly but has not enacted change. The FSA\'s ongoing review of the Payment Services Act framework has included tax considerations.
As of May 2026, no formal proposal has been tabled in the Diet. Industry observers expect any change to come as part of a broader crypto regulatory update during 2025–26, but no specific timeline is committed.
Frequently Asked Questions — Japan Crypto Tax
How much tax do I pay on crypto in Japan?
Crypto gains are aggregated with your other income and taxed at the progressive national rate (5%–45%) plus 10% local resident tax. Combined marginal rates range from approximately 15% at the bottom to 55% at the top. Unlike listed equities, crypto receives no preferential flat-rate treatment.
Why is Japanese crypto tax so high?
Japan's Income Tax Act categorises crypto as miscellaneous income, the highest-tax category. The NTA has resisted reclassification despite industry lobbying. Japan's overall personal tax rates are relatively high (top combined ~55%) and crypto falls fully within that progressive structure.
Can I offset crypto losses in Japan?
Limited. Losses on crypto can offset other miscellaneous income in the same year, but cannot offset salary income, business income, or capital gains. Unused losses cannot be carried forward. This is materially less favourable than the loss treatment for listed equities.
Are crypto-to-crypto trades taxed in Japan?
Yes. The NTA treats crypto-to-crypto swaps as a disposal of the given-up asset at fair market value, generating misc income on the gain. Frequent swapping creates a high tax-event count.
Do I need to report crypto held on foreign exchanges?
Yes. Japanese tax residents are taxed on worldwide income. Crypto held on foreign exchanges is reportable on the Final Income Tax Return. Foreign assets above ¥50 million require the Foreign Asset Report (kokugai zaisan chōsho).
Is Bitcoin treated differently from altcoins for tax?
No. All cryptoassets are uniformly treated as misc income for individual investors. The treatment does not differ between Bitcoin, Ethereum, stablecoins, or smaller altcoins.
Will Japan reform its crypto tax?
Active discussion but no enactment as of 2026. The most-discussed proposal: flat 20.315% taxation matching listed equities, plus 3-year loss carry-forward. The LDP tax committee has reviewed the proposal multiple times. Any change would likely take effect from the following fiscal year and apply to subsequent activity only.
