Can the store simply deduct the tax at the register like before?
No. Under the new system, Tax-Free sales are processed using tax-inclusive payment followed by a refund after customs confirmation.
This page is general reference information based on Japan's refund-based Tax-Free system starting November 1, 2026. Procedures and rules may differ by store, refund provider, airport or port, and may change. Please check the latest information with the Japanese government or the store where you shop.
