Per ArgentumWealth April 8, 2026 via DDGS text "Japan crypto tax 55 to 20":

It means that you could be looking at taxes on your gains of up to 55%. That's right, Japan will take most of the winnings on your crypto asset bet, even though you took all the risk.

Details from Koinly, TokenTax, MEXC Complete Guide June 4 2026 via DDGS:

• Current until fiscal 2027/Jan 2028: Crypto gains taxed as miscellaneous income added to other earnings at progressive national 5-45% + flat 10% local inhabitant tax = up to 55% — TokenTax guide April 6 2026
• New from Jan 2028 / fiscal 2027: 20% flat same as stocks — separate self-assessed — same as equities — Kucoin flash, Binance Square headline "20% Tax Rate, Bitcoin ETF Framework, and 10-Year Prison Terms"
• Math: ¥10M gain ($67K) old tax ¥5.5M vs new ¥2M — saves ¥3.5M ($23K) — incentive to realize gains and re-enter = volume boost
