📋 Quick Summary for Foreign Business Owners

Category: Regulatory Update
Background & Context
The Japanese customs system relies on foreign exchange rates to determine the value of imported and exported goods for tariff calculations. The Ministry of Finance (Zaimu-shō) publishes these rates regularly, ensuring that businesses have a consistent basis for pricing. The current legal framework is governed by the Customs Act (Kanzei-hō) of 2018, which outlines the procedures for customs valuation and the use of foreign exchange rates. The recent update, effective from April 26 to May 2, 2026, reflects fluctuations in the global market and aims to maintain fairness in trade practices. Historically, Japan has adjusted these rates bi-weekly, and foreign exchange rates are crucial for businesses to accurately assess their customs duties and taxes. The last significant amendment to the Customs Act occurred in 2021, which introduced more flexible valuation methods to accommodate international trade dynamics.How This Affects Your Business in Japan
