Understanding foreign exchange rates is crucial for foreign entrepreneurs involved in import and export activities in Japan. The latest update from the Japanese Customs provides the foreign exchange rates applicable for customs pricing from April 26 to May 2, 2026. This information is vital for accurate pricing and compliance with customs regulations, ensuring that your business operations remain smooth and legally compliant.

Background & Context

The foreign exchange rates used for customs pricing in Japan are governed by the Customs Act (Zeikan-ho) of 2018, which outlines the procedures for calculating the value of imported goods. The Ministry of Finance (Zaimu-shō) is responsible for publishing these rates, which are essential for determining the customs duties applicable to imported goods. The exchange rates are updated weekly, reflecting fluctuations in the global currency markets. The latest rates, effective from April 26 to May 2, 2026, are crucial for businesses engaged in international trade, as they directly impact the cost of imports and the calculation of tariffs. Understanding these rates helps businesses avoid overpayment of duties and ensures compliance with Japanese customs regulations.
