Foreign Exchange Rates for Customs Valuation in Japan: April 2026

Understanding the foreign exchange rates used for customs valuation in Japan is crucial for foreign entrepreneurs engaged in import and export activities. From April 26 to May 2, 2026, the Japanese government will implement updated exchange rates that directly affect the valuation of goods for customs purposes. This change can impact the costs and pricing strategies for businesses operating in Japan, making it essential for foreign business owners to stay informed and adapt accordingly.

Background & Context

The foreign exchange rates used for customs valuation in Japan are governed by the Customs Act (Zeikan-hō) of 2014, which outlines the procedures for determining the value of imported goods. The Ministry of Finance (Zaimu-shō) is responsible for publishing the foreign exchange rates that are applied during specific periods. These rates are crucial as they influence the duties and taxes levied on imported goods, impacting overall import costs. The current legal framework requires that the exchange rates be updated regularly to reflect market conditions, with the latest updates being published weekly. The upcoming rates from April 26 to May 2, 2026, are part of this ongoing regulatory process, ensuring that businesses have access to the most accurate data for customs valuation.

2. Foreign Nationals Planning to Establish a New Company
If you are looking to start a business in Japan that involves importing goods, familiarize yourself with the customs valuation process and the impact of exchange rates on your costs. It is advisable to consult with a customs broker or legal advisor to ensure compliance with the latest regulations and to prepare your financial projections accurately.
