How to Trade Bitcoin (BTC) in Japan

From Japan, exposure to Bitcoin runs through a USDC-settled perpetual.

Is Bitcoin trading legal in Japan?

Spot crypto and leveraged crypto derivatives are two different regimes in Japan and both are legal, but each is gated by a licence. Holding and trading spot crypto-assets is lawful; since 1 April 2017 anyone providing exchange services between crypto-assets and fiat inside Japan must be registered as a crypto-asset exchange service provider (暗号資産交換業者) under the Payment Services Act, and the FSA tells users to check that the operator they use is registered.

The FSA also states plainly that crypto-assets are not legal tender. Leveraged products — perpetuals, margin and other crypto derivatives — sit under a second regime: from 1 May 2020 crypto-asset derivative transactions fall under the Financial Instruments and Exchange Act, and a business carrying them on had to notify the FSA.

What the contract is

The contract itself does not change by geography: a BTC perpetual settles in USDC everywhere.

Choose Buy / Long, then set size and leverage

Buying $1,000 of BTC at 5x uses $200 of collateral. Higher leverage moves the liquidation price closer to your entry: your exposure is the position size, whatever margin you posted. Set a stop-loss below your entry before you walk away.

Crypto-asset income is assessed as miscellaneous income (雑所得) under the Income Tax Act (所法35). The NTA's own worked example — compensation paid in yen in place of crypto-assets — is taxed 雑所得として課税の対象.
