Crypto wallets in Japan
Whether wallets and self custody are legal, when a provider must register, and how wallet movements are taxed.
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.
Using a crypto wallet is legal in Japan as of January 2026. Holding your own keys in a self custody wallet is not a regulated activity and needs no licence. A business that holds crypto for others, a custodial wallet provider, is regulated under the Payment Services Act and must register with the Financial Services Agency (FSA). This is not legal or investment advice.
Are crypto wallets legal in Japan
Yes. As of January 2026 owning and using a crypto wallet is legal in Japan. If you hold your own private keys in a self custody wallet, whether software or hardware, you are not carrying on a regulated financial activity, so there is no licence to obtain and no FSA registration to make. The act of storing your own crypto is treated much like holding your own property.
The regulated question is custody for others. A business that holds or manages crypto assets on behalf of users, a custodial wallet provider, falls under the Payment Services Act and must register with the Financial Services Agency (FSA). The 2026 amendments to the Payment Services Act, operational from 13 June 2026, broadened and clarified the registration scope for custodial and intermediary roles, reinforcing that whoever controls customer assets carries regulatory duties such as segregating those assets.
Self custody and exchange wallets
In practice residents use two kinds of wallet. The wallet inside an FSA registered exchange is custodial, so the platform holds the keys and the exchange regime, including asset segregation rules, applies. A self custody wallet puts control and responsibility on you. Self custody is fully legal, but losing a seed phrase or sending to a wrong address has no customer support behind it. As of January 2026 there is no rule in Japan that forces residents off self custody, although transfers between registered providers carry travel rule information.
Tax and wallets
Holding crypto in a wallet, and moving it between your own wallets, is not by itself a taxable event in Japan. The National Tax Agency (NTA) taxes disposals, which means selling for yen, swapping for another crypto asset, or spending it. So a transfer from an exchange to your own hardware wallet is not taxable, but the later sale of that crypto can be. Keep dated records across all your wallets so gains can be worked out. As of January 2026 the proposed flat 20 percent rate applies only to specified crypto assets traded on registered platforms, not to wallet movements. This is information, not tax advice. See the Japan tax page.
