Category: Regulatory Update
Background & Context
The Japanese customs framework is governed by the Customs Act (Yusohou) of 2014, which outlines the procedures and regulations for importing goods into Japan. Anti-dumping duties are imposed to protect domestic industries from unfair competition posed by foreign imports sold at below fair market value. The Ministry of Finance (Zaimusho) is responsible for enforcing these duties. Recent amendments have been made to strengthen the enforcement of anti-dumping measures, particularly concerning imports from third countries that may be used to circumvent these duties. The new guidelines, published on April 25, 2026, provide a detailed framework for businesses to follow in order to comply with these regulations and avoid penalties. This is part of Japan’s ongoing commitment to fair trade practices and the protection of its domestic market.How This Affects Your Business in Japan

1. Foreign Residents Already Operating a Business in Japan
If you are already importing goods, it is crucial to review your supply chain to ensure compliance with the new anti-dumping duty guidelines. You may need to provide documentation proving the origin of your goods. Failure to comply could result in significant fines or the imposition of anti-dumping duties. Ensure you have the necessary paperwork ready for customs inspections.
2. Foreign Nationals Planning to Establish a New Company
For those looking to start a business in Japan, understanding these guidelines is essential. You will need to conduct thorough market research to identify potential suppliers and ensure that they are not subject to anti-dumping duties. This may involve obtaining certificates of origin and other documentation from suppliers. Delays in compliance could hinder your ability to launch your business effectively.
3. Foreign Investors Who Are NOT Residents of Japan
If you are considering investing in Japanese companies that import goods, be aware of the potential risks associated with anti-dumping duties. Conduct due diligence on the companies you are interested in to ensure they are compliant with the new guidelines. Investing in non-compliant businesses could lead to financial losses due to unexpected duties or penalties. It is advisable to consult with legal experts familiar with Japanese trade regulations to mitigate these risks.
