Cryptocurrency in Japan: regulation, taxes and licensing
In short. Crypto is legal in Japan, and its exchange licensing regime is one of the oldest anywhere — it grew directly out of the two largest hacks in the industry's history. Tax, meanwhile, is the heaviest in the developed world: gains count as miscellaneous income on a progressive scale reaching about 55%. A reform cutting that to a flat 20% has been drafted but not enacted.

Who regulates crypto in Japan
Japanese rules were written in the aftermath of other people's losses. In 2014 the Tokyo exchange Mt.Gox collapsed, and at the time most of the world's bitcoin trading ran through it. In 2018 the domestic venue Coincheck lost roughly half a billion dollars to a hack. Each episode tightened the rules, which is why Japan had a licensing regime long before almost anyone else.
Since 2017 an exchange must register with the Financial Services Agency. The requirements are about how the business runs rather than what it files: client funds are segregated from the firm's own, a substantial share sits in cold storage, and systems and staff are examined. A self-regulatory industry association operates alongside, maintaining the lists of tokens cleared for trading.
Stablecoins live under the payment services law rather than the securities regime. The country's three largest banks are preparing a joint yen stablecoin for live commercial settlement.
What is being rebuilt
The Financial Services Agency has drafted a rework of the whole structure: crypto assets would be reclassified as financial products under the financial instruments legislation. Everything else follows from that — disclosure obligations for the 105 tokens traded on domestic exchanges, insider trading rules, and, for private investors, a separate 20% tax rate in place of the progressive scale.
The bill still has to pass the Diet. Until it does, the old rules apply.
Tax: why 55%, and who the reform will not rescue
Today a crypto gain in Japan is miscellaneous income. It is added to salary and everything else and taxed progressively; with local tax the top approaches 55%.
The contrast with equities is stark — those are taxed separately and far more lightly. That mismatch is the central argument behind the reform.
The coming relief carries a caveat worth reading before relocating. The lower rate is designed for trading on registered Japanese venues. Staking rewards, income from lending and decentralised protocols, NFT transactions, and trading on foreign or unregistered exchanges all stay miscellaneous income at up to 55%. The system becomes two-tier rather than simply gentler.
Allowed
- Trade on exchanges registered with the FSA
- Use yen stablecoins for settlement
- Hold assets with a licensed custodian
- Mine, declaring the income
Restricted
- Up to 55%, because gains stack on top of your other income
- Trading on an unregistered venue will miss the coming lower rate
- Staking, lending and NFTs stay miscellaneous income
- A token reaches the order book only after association review
How the rules took shape
Mt.Gox, then the largest exchange in the world, collapses. Japan starts writing rules before anyone else.
The payment services act makes exchange registration with the Financial Services Agency mandatory.
Coincheck loses roughly half a billion dollars to a hack, and custody requirements tighten.
Stablecoins get their own framework within the payment services regime.
The agency tables its bill: crypto as financial products, disclosure for 105 tokens, a 20% rate.
Worth knowing
In February 2014 Tokyo-based Mt. Gox collapsed, taking some 850,000 BTC with it — at its peak the exchange handled up to 80% of global bitcoin trading. That failure pushed Japan to write the world's first law on crypto exchanges.
Common questions
How much tax do you pay on crypto in Japan?
Today gains are miscellaneous income on a progressive scale reaching about 55% with local tax. A 20% reform is drafted but not yet law.
When does the 20% rate start?
Once the Diet passes the bill. 2026 is the target, but it remains a bill rather than a statute.
Will staking qualify for the lower rate?
No. Staking rewards, lending and DeFi income and NFT transactions all stay miscellaneous income.
Can I trade on a foreign exchange?
Personal trading is unrestricted, but it will not qualify for the coming lower rate, which is designed for registered Japanese venues.
Why did Japan license exchanges so early?
Because of the industry's two biggest hacks: Mt.Gox in 2014 and Coincheck in 2018. The rules were written as a response to them.
