Background & Context
Japan has a comprehensive legal framework governing trade, particularly concerning anti-dumping measures. The Anti-Dumping Act (Hanbai Shingai-hō) was enacted to protect domestic industries from unfair competition caused by foreign products sold below fair market value. The Ministry of Finance (Zaimu-shō) oversees the implementation of these regulations, ensuring that imported goods do not undermine local businesses. Recent amendments to the Act have introduced stricter guidelines for foreign imports, particularly those sourced from third countries. As of April 2026, businesses must submit detailed documentation to justify the pricing of imported goods to avoid anti-dumping duties. This regulatory shift reflects Japan’s commitment to fair trade practices and its intention to safeguard its market from unfair pricing strategies.How This Affects Your Business in Japan

If you are currently importing goods, it is crucial to review your pricing strategies and ensure compliance with the new anti-dumping regulations. You may need to prepare documentation that demonstrates the fair market value of your products. Failure to comply could result in significant financial penalties. It is advisable to consult with a trade compliance expert or legal advisor to assess your current imports and make necessary adjustments.
2. Foreign Nationals Planning to Establish a New Company
For those looking to start a business in Japan, understanding these regulations is vital before importing goods. You will need to prepare a comprehensive business plan that includes pricing strategies aligned with Japanese anti-dumping laws. Additionally, you should familiarize yourself with the necessary documentation required for importation to avoid potential delays or penalties.
3. Foreign Investors Who Are NOT Residents of Japan
