How to buy Polkadot (DOT) in Japan
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.
Buying Polkadot (DOT) is legal in Japan through a crypto asset exchange registered with the Financial Services Agency, such as bitFlyer, as of June 2026. Japanese exchanges may only list tokens that clear the screening of the Japan Virtual Currency Exchange Association. You complete identity checks, fund in yen, and buy. Crypto profits are generally taxed as miscellaneous income at progressive rates administered by the National Tax Agency. This is general information, not investment advice.
Is it legal to buy Polkadot in Japan?
Yes. Buying, holding, and selling Polkadot (DOT) is legal in Japan as of June 2026. Crypto assets are recognised under the Payment Services Act, and platforms that serve residents must register as crypto asset exchange service providers with the Financial Services Agency (FSA) and follow anti money laundering and know your customer rules. DOT is not legal tender.
A distinctive feature of the Japanese market is token screening. Exchanges may only list crypto assets that have cleared review through the Japan Virtual Currency Exchange Association (JVCEA), the self regulatory body, so the set of available coins is more curated than in many markets. Polkadot is available on registered exchanges that have listed it, such as bitFlyer. Japan has also signalled a move to treat crypto assets as financial products under the Financial Instruments and Exchange Act, which could change disclosure and tax rules. Confirm a platform registration and a coin listing before you sign up. Nothing on this page is a view on whether you should buy DOT or at what price.
The steps to buy Polkadot legally
1. Choose a registered exchange
Pick an exchange registered with the Financial Services Agency that lists Polkadot. As of June 2026 bitFlyer is among the registered exchanges that support DOT. Confirm the current registration and listing before signing up.
2. Complete identity verification
Registered exchanges must verify your identity under anti money laundering rules. You will provide identity documents and often proof of address before you can deposit and trade. This is current to June 2026.
3. Fund in yen and buy DOT
Fund the account in yen using the platform supported methods, then place an order for Polkadot. Fees vary by platform and order type. The buy itself is not a taxable event.
4. Decide on custody and keep records
You can leave Polkadot in custody on the exchange or move it to a self custody wallet you control, which is legal in Japan. Keep records of your yen cost, because tax reporting applies when you later sell, swap, or spend the DOT.
Tax on Polkadot in Japan
The National Tax Agency (NTA) generally treats crypto profits as miscellaneous income, as of June 2026. Buying and holding Polkadot is not a taxable event, but disposing of it, by selling it for yen, swapping it for another token, or using it to pay for something, generally produces miscellaneous income that is taxed at progressive rates and aggregated with your other income, with local inhabitant tax also applying. Japan has signalled possible reform that could move crypto toward a financial product style tax treatment, so the position may change. Keep records and confirm your treatment with the National Tax Agency and a qualified Japanese tax professional before filing. This is general information, not tax advice.
