Background & Context

The Japanese Customs (Nihon Zeikan) regulates the foreign exchange rates used for customs valuation, which is essential for determining the value of imported goods. The current legal framework is governed by the Customs Act (Zeikan-ho) of 2018, which stipulates how foreign exchange rates are to be applied for customs purposes. The rates are updated regularly, typically on a weekly basis, to reflect the fluctuations in the foreign exchange market. The latest update, effective from April 26 to May 2, 2026, is crucial for businesses involved in international trade, as it directly affects the customs duties and taxes that must be paid upon importation. This update is part of Japan’s ongoing efforts to align its customs procedures with international standards and to facilitate smoother trade operations.

Keep records of your transactions and consult with a customs broker if necessary.

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. You will need to factor in these exchange rates when calculating the cost of imported goods.

Engaging with a local expert or customs consultant can provide valuable insights into compliance and cost management.
