Note: Japan's refund-based Tax-Free system (pay the tax-inclusive price first, then receive a refund after customs confirmation) starts on November 1, 2026. Until October 31, 2026, the current Tax-Free system (tax-excluded price at the register) continues. The answers below describe the system from November 1, 2026 unless stated otherwise.
Under Japan’s tax-free system, information on the goods you bought (the purchase record) is registered in the National Tax Agency’s system, and the customs confirmation at departure is based on that information.
If the purchase record has not arrived by the time of the customs confirmation — for example because of a communication failure or system problem at the shop — you cannot go through the customs confirmation for those goods.
Even if the shop sends the purchase record after you leave Japan, the customs confirmation cannot be done retroactively, so the goods are not eligible for tax exemption.
If your purchase history cannot be found, contact the shop or the refund operator (TRO) before leaving Japan.
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.
