In short
In Japan, gains on crypto assets are in principle treated as miscellaneous income and taxed on an aggregate basis. Confirm your own situation with the tax office or a tax professional.
Key points
- Gains arise not only on sale but on crypto-to-crypto swaps and on spending
- Keep trade history across tax years
- Have a professional confirm your actual filing
Definition
Tax on income arising from crypto transactions. In Japan this is generally miscellaneous income under aggregate taxation.
The most commonly missed point: swapping one crypto asset for another realises a gain or loss even if you never convert back to yen.
Beyond the annual statements exchanges provide, you will also need wallet transfers and DeFi activity. Calculation tools cut the effort substantially.
Tax rules change. What is written here is a general orientation, not advice on your situation — always check the National Tax Agency's current published material.
