Background & Context
The Japanese Customs (Nihon Zeikan) regulates the foreign exchange rates used for customs pricing, which is essential for calculating the value of imported goods. The foreign exchange rates are updated periodically and are crucial for determining the correct customs duties and taxes. The current legal framework governing these rates is outlined in the Customs Act (Zeikan-ho) of 2018, which stipulates that the rates must reflect the market conditions to ensure fairness and transparency in trade. The latest update, effective from April 26 to May 2, 2026, is part of the ongoing efforts by the Japanese government to maintain a stable trade environment and provide clarity to foreign businesses operating in Japan. Historically, the rates have been adjusted weekly, and businesses must stay informed to comply with customs regulations and avoid penalties.How This Affects Your Business in Japan

1. Foreign Residents Already Operating a Business in Japan
For those already engaged in import or export activities, it is crucial to regularly check the updated foreign exchange rates published by the Japanese Customs. Failure to use the correct rates can lead to miscalculated duties, resulting in financial penalties. Ensure that your accounting systems are updated to reflect these changes promptly. Typically, businesses should review these rates weekly, especially when preparing customs declarations.
2. Foreign Nationals Planning to Establish a New Company
If you are considering starting a business that involves importing or exporting goods, understanding the foreign exchange rates is essential. You will need to incorporate these rates into your pricing strategy to ensure competitiveness and compliance. It is advisable to consult with a local customs broker or legal advisor to navigate these regulations effectively. Prepare to gather documentation related to your goods, including invoices and shipping details, to facilitate accurate customs declarations.
3. Foreign Investors Who Are NOT Residents of Japan
For foreign investors looking to enter the Japanese market, being aware of the foreign exchange rates is vital for assessing the profitability of potential investments. If you plan to invest in import-export businesses, ensure that you have a clear understanding of how these rates impact your financial projections. Engaging with local financial advisors or customs experts can provide valuable insights and help mitigate risks associated with currency fluctuations. Inaction can lead to significant financial losses, especially in a fluctuating market. Regularly consulting the Japanese Customs website for updates is recommended, as well as maintaining open communication with local partners.
