Japan is implementing the most significant overhaul of its cryptocurrency rules in more than five years. Starting in 2026, the Financial Services Agency (FSA) is reclassifying major digital assets as financial products under the Financial Instruments and Exchange Act (FIEA), cutting the top crypto tax rate from 55% to a flat 20% for qualifying assets, and introducing mandatory disclosure requirements, insider trading prohibitions, and stricter oversight for registered exchanges. The changes affect every resident, trader, and business that holds or trades crypto in Japan.

What changed in Japan’s crypto rules in 2026?

What changed in Japan's crypto rules in 2026

The 2026 reforms represent a coordinated shift across taxation, exchange regulation, and asset classification. The key changes that came into effect or were legislated in 2026 are as follows:

  • Flat 20% tax rate on gains from trading specified crypto assets on FSA-approved exchanges, replacing progressive rates of up to 55%.
  • Three-year loss carryforward for losses on specified crypto assets, a first in Japan’s crypto tax history.
  • Corporate exemption on unrealized gains for companies holding crypto long-term, effective from April 1, 2026.
  • Reclassification of 105 approved cryptocurrencies as financial products under the FIEA, bringing them under securities-level oversight.
  • Mandatory disclosure requirements for exchanges listing any of the 105 approved tokens.
  • Insider trading prohibitions applied to crypto markets for the first time.
  • Regulated crypto ETFs and investment trusts now permitted under the new framework.
  • Banks and bank groups under consideration to hold Bitcoin and register as licensed crypto exchanges.

The Japan Blockchain Association (JBA) had been lobbying for the tax reform since 2022, describing the previous income-based system as the single biggest obstacle to Web3 growth and retail participation. The government and the FSA moved together on the proposal, which passed through Japan’s parliamentary session in early 2026. Understanding what cryptocurrencies are and how they function as assets helps contextualize why these regulatory changes matter. A foundational explanation is available in the guide to what is crypto.

Japan crypto tax: from 55% to 20%

Before 2026, Japan taxed crypto gains as miscellaneous income (雑所得, zatsu shotoku). Profits from selling, swapping, or spending cryptocurrency were added to all other income and taxed at progressive national rates from 5% to 45%, plus a flat 10% residence tax (住民税, juminzei). The combined maximum rate reached 55% for high earners. Stocks and bonds, by contrast, were taxed at a flat 20%.

Japan crypto tax from 55% to 20%

The 2026 reform introduces a separate self-assessment tax (申告分離課税) at a flat rate of 20.315% (15% national income tax, 5% residence tax, plus a 2.1% reconstruction surtax applied to the national portion) for gains on specified crypto assets. This aligns crypto with the tax treatment of equities and investment trusts in Japan.

Who qualifies for the 20% flat rate?

The 20% rate applies to specified crypto assets (特定暗号資産), defined as tokens listed on exchanges registered in Japan’s Financial Instruments Business Operator Registry. Bitcoin, Ethereum, and approximately 105 other assets listed on FSA-approved platforms such as bitFlyer, Coincheck, and GMO Coin are expected to qualify. The qualifying list covers the major assets most retail traders in Japan hold.

What is still taxed at up to 55%?

The reform creates a two-tier system. Assets and activities that remain taxed as miscellaneous income at progressive rates include:

  • Tokens traded on unregistered or foreign exchanges
  • DeFi yields, staking rewards, and liquidity pool income
  • NFT proceeds
  • Tokens not listed on any domestic FSA-licensed exchange

Staking rewards and DeFi income remain in the high-tax category regardless of which token is involved. A trader earning yield on Ethereum through a DeFi protocol pays at the old progressive rates, even though spot trading of Ethereum on a licensed exchange now qualifies for the 20% rate. The distinction is the activity, not the asset.

Three-year loss carryforward: a first for Japan

Before 2026, crypto losses in Japan could not be carried forward to offset gains in future years. The 2026 reform changes this for specified assets. A loss of ¥1,000,000 on qualifying crypto in 2026 can now reduce taxable gains in 2027, 2028, or 2029. This three-year loss carryforward matches the treatment already available for stock market losses under Japan’s financial instruments framework and brings crypto into line with standard investment taxation principles.

Corporate exemption on unrealized gains

Japanese companies holding crypto assets at the end of each fiscal year were previously required to pay tax on unrealized gains calculated using mark-to-market accounting. This forced companies to pay tax on paper profits even if they had not sold a single coin. Starting April 1, 2026, companies holding specified crypto assets as long-term investments are exempt from this year-end mark-to-market tax. This change is widely credited with slowing the departure of crypto businesses from Japan to lower-tax jurisdictions like Dubai and Singapore. How Bitcoin functions as an asset and why corporations have begun holding it is covered in the guide to what is Bitcoin.

How crypto is taxed in Japan: income brackets

For assets and activities that still fall under the old miscellaneous income system, the following progressive brackets apply. National income tax rates stack on top of the flat 10% residence tax.

Taxable income (JPY) National income tax rate Residence tax Effective total rate
Up to 1,950,000 5% 10% 15%
1,950,001 to 3,300,000 10% 10% 20%
3,300,001 to 6,950,000 20% 10% 30%
6,950,001 to 9,000,000 23% 10% 33%
9,000,001 to 18,000,000 33% 10% 43%
18,000,001 to 40,000,000 40% 10% 50%
Over 40,000,000 45% 10% 55%

Crypto gains classified as miscellaneous income stack on top of salary and business income, pushing traders into higher brackets. A salaried worker already in the 33% national bracket who made ¥5,000,000 in DeFi profits would pay 43% effective rate on those gains. The 200,000 JPY annual exemption means that residents with total miscellaneous income below ¥200,000 (including crypto) may be exempt from filing a separate tax return for those gains.

Taxable crypto events

The National Tax Agency (NTA) treats the following as taxable disposals or income:

  • Selling crypto for Japanese yen or any fiat currency
  • Swapping one cryptocurrency for another (the gain on the sold asset is taxable at the time of the swap)
  • Spending crypto to buy goods or services (fair market value of goods received is the proceeds)
  • Mining rewards (taxed as income at fair market value on receipt)
  • Staking rewards and DeFi yield (taxed on receipt at spot price)
  • Airdrops with a determinable market value at the time of receipt
  • Crypto received as salary or payment for services

Non-taxable crypto events

  • Buying crypto with Japanese yen or fiat currency
  • Transferring crypto between wallets you own
  • Simply holding crypto assets
  • Receiving an airdrop with no determinable market value at receipt (tax is deferred until a price is established)

Whether you store Bitcoin on an exchange or in your own cold wallet does not change the taxable event. The tax event is triggered by disposal or receipt of income, not by where the asset is held. The distinction between holding crypto on a licensed exchange versus in self-custody is covered in the guide to custodial vs non-custodial wallets.

FSA regulation: the legal framework

Japan’s Financial Services Agency is the primary regulator for all crypto activity in the country. Its authority was established through two main laws: the Payment Services Act (PSA), which has governed crypto exchanges since 2017, and the Financial Instruments and Exchange Act (FIEA), which expanded to cover crypto assets in 2026.

Payment Services Act vs FIEA: the 2026 shift

The two laws govern different aspects of the market and impose different obligations on the industry.

Feature Payment Services Act (PSA) Financial Instruments and Exchange Act (FIEA)
Primary focus Operational safety, AML/KYC Investor protection, market conduct
Asset classification Crypto-assets (property) Financial instruments (securities-like)
Disclosure requirements Basic registration information Mandatory detailed financial disclosures
Enforcement scope FSA licensing and custody rules FSA plus securities laws
Impact on exchanges Licensing and cold wallet mandate Listing standards and trading surveillance

The PSA came into effect after the 2014 collapse of Mt. Gox, when Japan was at the center of the worst exchange failure in crypto history. Rather than banning digital assets, Japanese regulators built a licensing regime that required exchanges to register, segregate customer funds, and meet strict operational standards. The FIEA layer added in 2026 brings the securities-style obligations that now apply to the 105 reclassified tokens: mandatory issuer disclosures, standardized risk information, and insider trading enforcement. The difference between Bitcoin and other cryptocurrencies in terms of how they are classified and regulated is covered in the guide to Bitcoin vs crypto.

The cold wallet mandate: 95% cold storage

Japan’s most distinctive exchange regulation is the cold wallet mandate. By law, registered exchanges must keep at least 95% of all customer crypto assets in offline cold storage. Hot wallets, those connected to the internet, may hold no more than 5% of customer assets. Any amount held in hot wallets must be backed by the exchange’s own corporate assets, not customer funds. If a hot wallet is drained by hackers, the exchange absorbs the loss. Customers are protected.

This risk transfer is uncommon globally. Most regulators tell exchanges to be secure without specifying exactly how. Japan specifies both the minimum cold storage percentage and the liability structure. The practical result is that Japanese exchanges carry significant insurance and capital buffers to cover their hot wallet exposure. The difference between hot and cold storage from a user’s perspective is explained in the guide to cold wallets for crypto.

Getting an FSA license: the barriers to entry

Operating a crypto exchange in Japan without an FSA license is illegal. The licensing process is deliberately demanding. Requirements include establishing a local Japanese entity (Kabushiki Kaisha, or joint stock company) with minimum capital above 10 million yen, maintaining a physical office with locally employed staff, implementing AML/KYC systems that meet international standards, proving the ability to meet the 95% cold storage requirement with audited technical documentation, and submitting detailed governance, risk management, and employee training plans to the FSA for review.

The FSA examines every application thoroughly. Hidden ownership structures and vague business models are rejected. As of 2025, Japan had approximately 30 registered virtual asset service providers operating under this framework. For companies operating exchanges outside Japan and considering entry into the Japanese market, the compliance cost is high. For users, the result is a pool of operators that have cleared a rigorous filter, which is one reason Japan’s cryptocurrency adoption rate reached approximately 14.70% of the population in 2025.

Insider trading rules: new for Japanese crypto

The 2026 FIEA reforms introduce insider trading prohibitions to Japan’s crypto market for the first time. Before 2026, no equivalent existed for digital assets. A trader with advance knowledge of an upcoming token listing, a planned delisting, or an issuer’s undisclosed financial difficulties faced no legal consequence for acting on that information.

Under the new rules, individuals and entities with access to non-public information about events that would materially affect the price of a listed token are prohibited from buying or selling that token until the information is publicly disclosed. This mirrors the protections that already apply in Japan’s equity and derivatives markets. Covered information includes upcoming exchange listings, planned delistings, and any material event involving a token issuer that has not been publicly announced. Penalties for violations follow the FIEA’s securities enforcement framework.

The insider trading rules are part of a broader package that treats major crypto assets more like securities than commodities. For retail investors, the change improves the fairness of price discovery on Japanese exchanges. For exchange operators and token projects, it creates new compliance obligations around information handling and timing of announcements. How Bitcoin specifically is classified and what makes it distinct from other crypto assets is explained in the guide to what is BTC in crypto.

The 105 approved tokens and disclosure requirements

The reclassification at the center of the 2026 reform applies to 105 cryptocurrencies currently listed on Japanese domestic exchanges. Bitcoin and Ethereum are the largest by market cap, but the list covers a broad range of assets that meet the FSA’s criteria for listing on regulated platforms. Tokens not on this list remain under the PSA framework and are not eligible for the 20% flat tax rate.

For each of the 105 tokens, exchanges are required to publish standardized disclosure information that includes whether the token has an identifiable issuer, details about the underlying blockchain or distributed ledger technology, the asset’s volatility profile and market risks, and any other material factors that could influence investor decisions. This level of disclosure brings crypto listings closer to the documentation requirements for securities offerings and gives retail investors a standardized information base for comparing assets.

The disclosure framework is designed to make the 105 approved tokens more transparent and comparable across exchanges. A token that qualifies for the regulated list must have sufficient public information available for exchanges to compile these disclosures. Tokens that lack identifiable issuers or have insufficient technical documentation may not qualify. The block reward structure of Bitcoin, including how it changes through halvings and how that affects supply, is part of the economic information investors might review when assessing BTC. That context is available in the guide to Bitcoin block reward.

What the reform means for DeFi, staking, and NFTs

The 2026 reform explicitly excludes several categories of crypto activity from the favorable 20% rate. Gains and income from DeFi protocols, staking, lending, liquidity mining, and NFT sales remain classified as miscellaneous income and continue to be taxed at progressive rates up to 55%. The FSA’s DeFi Study Group has been working through how to apply regulatory oversight to decentralized protocols, but no full DeFi framework has been finalized as of mid-2026.

The practical implication is a two-tier system. Buying Ethereum on a licensed Japanese exchange and later selling it qualifies for the 20% rate. Depositing that same Ethereum into a DeFi lending protocol and collecting yield does not. The yield is taxed as miscellaneous income at progressive rates. If you then sell the Ethereum after withdrawing it from the protocol, that sale goes back to the 20% rate, but the yield earned along the way was taxed differently.

For staking specifically, rewards are taxed at fair market value on receipt under the miscellaneous income classification. A staker receiving weekly ETH rewards must record the yen value of each reward at the time it arrives in the wallet. Those rewards also have their own cost basis for any future disposal. The administrative burden of tracking staking rewards across multiple assets and multiple protocols remains significant even after the 2026 reforms. The guide to hot wallets for crypto covers how connected wallets interact with DeFi protocols and what that means for security and custody.

Japan crypto regulation: how it compares globally

Japan’s approach to crypto regulation is frequently cited as one of the more structured frameworks among major economies. The PSA licensing regime established after Mt. Gox created a template that several other jurisdictions later studied. The 2026 FIEA expansion puts Japan closer to the European MiCA framework in terms of treating certain crypto assets as regulated financial instruments with mandatory disclosures.

The tax reform moves Japan from one of the most punitive regimes to a more competitive one. Germany exempts long-term crypto holdings from tax entirely after one year. The United Kingdom taxes crypto gains at 10% to 20% depending on income. The United States applies capital gains rates of 0%, 15%, or 20% depending on income and holding period. Japan’s new flat 20.315% rate sits in line with most European approaches and below the US top rate, though the exclusion of DeFi and staking from the favorable rate creates more complexity than most comparable frameworks.

For global crypto companies considering Japan, the FSA’s licensing process remains demanding. The 90% of domestic exchanges currently operating at a loss, as reported to the FSA’s Financial Services Council working group, reflects the combination of high compliance costs and competitive fee pressure. Despite that, Japan’s regulated market attracted approximately 18.69 million crypto users by 2026 and represents one of the largest retail crypto markets in Asia. The guide to crypto seed phrase storage is relevant for Japanese users storing assets in self-custody wallets outside the exchange system.

Frequently asked questions

When does the 20% crypto tax take effect in Japan?

The flat 20% tax rate on specified crypto assets applies to transactions from the 2026 tax year onward. The corporate exemption on unrealized gains took effect from April 1, 2026. Gains on qualifying assets earned before 2026 remain subject to the old progressive rate system. The full 20% regime applies to trades conducted on FSA-registered exchanges for the 105 approved tokens from January 1, 2026 onward for individual traders.

Does the flat 20% rate apply to DeFi and staking?

No. DeFi yields, staking rewards, liquidity pool income, and NFT proceeds remain classified as miscellaneous income and are taxed at progressive rates up to 55%. The 20% flat rate applies only to specified crypto assets traded on FSA-registered exchanges. The activity type matters: spot trading of an approved token on a licensed exchange qualifies; earning yield on that same token through a DeFi protocol does not.

What is the cold wallet mandate in Japan?

Japan requires registered crypto exchanges to hold at least 95% of all customer assets in offline cold storage. Hot wallets may hold no more than 5% of customer funds, and any amount in hot wallets must be fully backed by the exchange’s own corporate capital. This means if a hot wallet is compromised, the exchange covers the loss from its own funds. Customers are not exposed to hot wallet hacking risk. This regulation is more specific than most jurisdictions, which leave storage security to the exchange’s discretion.

Can foreign exchanges operate legally in Japan?

Foreign exchanges cannot legally offer services to Japanese residents without first obtaining an FSA license. Operating without registration is illegal under the Payment Services Act. To register, a foreign company must establish a local Japanese entity (Kabushiki Kaisha), maintain a physical office in Japan, employ local staff, and meet all cold storage, AML/KYC, and governance requirements. Remote-only operations are not permitted. This applies to both crypto exchanges and entities offering crypto investment products.

Does the NTA track crypto transactions?

Yes. The National Tax Agency has access to transaction data from FSA-registered Japanese exchanges through reporting requirements. The NTA has also been active in sending inquiry notices to traders who hold accounts on domestic exchanges and have not reported crypto income. For trades on foreign exchanges not registered in Japan, direct reporting obligations are less immediate, but Japanese residents are required to declare worldwide income. The NTA has issued guidance confirming that offshore crypto holdings are subject to Japanese tax rules for residents.

What is the 200,000 JPY exemption?

Japanese residents with total miscellaneous income below 200,000 JPY in a tax year may be exempt from filing a separate final tax return (kakuteishinkoku) for that income. This includes crypto gains still classified as miscellaneous income. Salaried workers whose employer handles their year-end tax adjustment can sometimes avoid filing if their total miscellaneous income, including crypto, stays below this threshold. The exemption applies only to the filing requirement for miscellaneous income, not to residence tax, which must still be paid. Residents with gains above 200,000 JPY must file a tax return by March 15 of the following year.
