Japan’s crypto tax reform debate expanded in 2026 as the Blockchain Collaborative Consortium held an April 21 panel on cryptocurrency and stablecoin taxation after a March 31 bill advanced separate self-assessment taxation for domestic trading of specified crypto assets. Separately, the Japan Cryptoasset Business Association and Japan Virtual and Crypto assets Exchange Association said in a June 30 tax reform request that crypto gains are currently treated as miscellaneous income, taxed progressively at 5% to 45%, with resident tax raising the maximum combined burden to 55%. Together, the developments highlight both momentum toward a different tax framework and unresolved implementation challenges for Japan’s digital asset market.
