Japan’s Foreign Exchange Rates for Customs Valuation April 2026

Understanding the latest foreign exchange rates is crucial for foreign entrepreneurs involved in import and export activities in Japan. The Japanese Customs (Zei-kan-kyoku) has released updated exchange rates for the period from April 26 to May 2, 2026, which will directly impact the customs valuation of goods. This update is essential for ensuring compliance with Japanese customs regulations and for accurate financial planning.

Background & Context

Japan’s customs valuation system relies heavily on accurate foreign exchange rates to determine the value of imported goods. The Customs Act (Kanzei-hou) governs these regulations, ensuring that all imports are assessed fairly and consistently. The exchange rates published by the Japanese Customs (Zei-kan-kyoku) are used to convert foreign currencies into Japanese yen for customs purposes. The current legal framework has evolved over the years, with significant amendments made to the Customs Act in 2021 to streamline processes and enhance transparency. The latest update on foreign exchange rates, effective from April 26 to May 2, 2026, reflects ongoing adjustments in the global market and is part of Japan’s commitment to maintaining a fair trade environment.

Check the Japanese Customs website for the latest rates and adjust your pricing strategies accordingly. Ensure you have documentation ready for any audits.

2. Foreign Nationals Planning to Establish a New Company
For those looking to start a business in Japan, understanding the customs valuation process is vital.
