Crypto mining in Japan
Whether mining is legal, the licence position, and how the National Tax Agency taxes the coins you mine.
This is general information, not legal, tax, or financial advice. Verify the current rules with a qualified local professional and the official regulator before acting.
Crypto mining is legal in Japan as of May 2026. There is no specific mining licence and no ban, but miners follow general business, electricity, and tax law. Coins you mine are taxable when received, generally as miscellaneous income for individuals or as business income at business scale, administered by the National Tax Agency (NTA). This is not tax or investment advice.
Is crypto mining legal in Japan
Yes. As of May 2026 mining bitcoin or other proof of work crypto assets is legal in Japan. There is no law that bans mining and no dedicated mining permit. Mining is not itself a regulated financial service, so a miner does not register with the Financial Services Agency (FSA) the way a crypto asset exchange must. The activity Japan regulates is exchanging crypto for yen, not producing it.
Mining still sits inside general Japanese law. You follow ordinary rules on running a business, on electricity supply contracts, and on tax. If you mine as part of an organised business you may also have company, consumer, and zoning obligations like any other operation that draws significant power. As of May 2026 there is no separate electricity tax aimed only at miners, although Japan's retail electricity prices are among the higher ones in the developed world, which is the real limit on home mining economics.
Mining pools and hosted mining
Joining a mining pool or paying a hosted mining or cloud mining provider is also legal. Take care with the second category. A scheme that pools other people's money and promises a managed return can, depending on its structure, look like a regulated financial product or a collective investment under the Financial Instruments and Exchange Act (FIEA), which the FSA oversees. As of May 2026 the line depends on the specific arrangement, so treat any cloud mining offer with caution and confirm how it is structured before committing funds.
Tax on mined crypto
Mining has two tax points and the National Tax Agency (NTA) treats them separately. First, when you receive mined coins, their market value at that moment is income. For an individual mining casually this is generally miscellaneous income, taxed at progressive rates with a combined marginal rate that can reach roughly 55 percent as of May 2026. Where mining is run at business scale it is generally business income instead, and reasonable costs such as hardware depreciation and electricity may be deductible. Second, when you later sell or swap the mined coins, any change in value from the receipt date is a further taxable gain or loss.
Japan's 2026 tax reform, which proposes a flat separate rate of about 20.315 percent for specified crypto assets traded on registered platforms, does not as of May 2026 extend that rate to mining rewards. Mining income remains in the higher progressive band. Keep dated records of the value of every payout and every disposal. This is information, not tax advice. See the Japan tax page for the wider picture.
