Background & Context

The foreign exchange rate is a critical factor for businesses engaged in import and export activities in Japan. The Ministry of Finance (Zaimu-shō) regularly publishes foreign exchange rates that are used for customs duties, pricing, and other financial transactions. The current legal framework governing these rates is primarily outlined in the Customs Act (Zeikan-hō) of 2018, which stipulates how exchange rates are determined and applied. The Ministry of Finance updates these rates weekly, providing businesses with the necessary information to calculate duties and prices accurately. The recent update for the week of May 3 to May 9, 2026, reflects fluctuations in the market and is essential for businesses to monitor. This update is part of a broader trend of increasing transparency in financial regulations, which aims to facilitate smoother trade operations for foreign businesses in Japan.

For those already established, it is vital to regularly check the foreign exchange rates published by the Ministry of Finance. These rates directly affect the pricing of imported goods and services. Failure to adjust your pricing in accordance with these rates could lead to financial losses or compliance issues. Ensure that your accounting systems are updated to reflect these rates promptly.

2. Foreign Nationals Planning to Establish a New Company
If you are planning to start a business in Japan, understanding the foreign exchange rates is crucial for budgeting and financial forecasting. You will need to account for these rates when setting prices for your products or services, especially if you are importing goods. It is advisable to establish a relationship with a local bank or financial institution that can provide guidance on currency exchange and help you navigate the complexities of pricing in a foreign currency.

3. Foreign Investors Who Are NOT Residents of Japan
For foreign investors looking to invest in Japanese businesses or assets, keeping an eye on the foreign exchange rates is essential.
