Background & Context
In Japan, the customs valuation process is governed by the Customs Act (Zeikan-ho) of 1954, which outlines how goods are valued for the purpose of calculating import duties and taxes. The exchange rates used for this valuation are crucial, as they determine the yen equivalent of foreign currencies. The Ministry of Finance (Zaimu-sho) regularly updates these rates to reflect current market conditions. The recent update, effective from April 26 to May 2, 2026, is part of the ongoing adjustments made to align with international currency fluctuations. Historically, Japan has maintained a structured approach to customs valuation, with periodic updates to ensure fairness and accuracy in trade practices. The latest rates can be found on the official website of the Customs and Tariff Bureau (Zeikan-kyoku) of the Ministry of Finance.How This Affects Your Business in Japan
