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. From April 26 to May 2, 2026, the Japanese Customs will implement updated exchange rates that directly affect customs valuation. This change can impact the cost calculations for goods entering or leaving Japan, making it essential for business owners to stay informed and compliant with these financial regulations.

Background & Context

The Japanese Customs and Tariff Bureau (Nihon Zeikan) regulates the foreign exchange rates used for customs valuation. These rates are crucial for determining the customs duties and taxes applicable to imported and exported goods. The current legal framework governing these rates is outlined in the Customs Act (Kanzei-hō), which mandates that the exchange rates be updated regularly to reflect market conditions. The rates are typically published weekly and are based on the average rates from the Tokyo foreign exchange market. The latest update, effective from April 26 to May 2, 2026, is part of the Bureau’s ongoing efforts to ensure fair and accurate customs assessments. It is important for foreign entrepreneurs to be aware of these changes as they can significantly affect the cost of doing business in Japan.

These rates will affect the valuation of your goods for customs purposes. Ensure that your accounting practices reflect these changes to avoid discrepancies that could lead to penalties.

2. Foreign Nationals Planning to Establish a New Company
If you are considering starting a business that involves import or export, understanding the customs valuation process and the impact of foreign exchange rates is critical.

3. Foreign Investors Who Are NOT Residents of Japan
For those looking to invest in Japanese businesses or markets, understanding the customs valuation and foreign exchange rates is essential, especially if your investments involve cross-border transactions.
