Japan Foreign Exchange Rates for Customs Valuation April 2026

Understanding foreign exchange rates is crucial for foreign entrepreneurs involved in import and export activities in Japan. The Japanese Customs (Nihon Zeikan) has updated its foreign exchange rates for the period from April 26 to May 2, 2026. This update directly impacts how businesses calculate customs duties and taxes, making it essential for foreign business owners to stay informed and compliant with these changes.

Background & Context

The Japanese Customs (Nihon Zeikan) regulates the valuation of goods for customs purposes based on foreign exchange rates. These rates are crucial for determining the value of imported goods, which in turn affects the calculation of tariffs and taxes. The current legal framework governing customs valuation in Japan includes the Customs Act (Zeikan-ho) 2018, which outlines the procedures for customs clearance and valuation. The foreign exchange rates are updated regularly to reflect market conditions, and the latest update is scheduled for the period from April 26 to May 2, 2026. This update is part of Japan’s ongoing efforts to maintain transparency and fairness in international trade.

2. Foreign Nationals Planning to Establish a New Company
If you are planning to start a business that involves importing goods, familiarize yourself with the customs valuation process and the importance of foreign exchange rates. You will need to prepare accurate financial projections that consider these rates. Consult with a customs broker or legal advisor to ensure compliance with the Customs Act (Zeikan-ho) and avoid costly mistakes.
