Category: Regulatory Update
Background & Context
The legal framework surrounding anti-dumping duties in Japan is primarily governed by the Customs Act (Zeikan-ho) and the Anti-Dumping Act (Fuhō Rōei-hō), which aim to protect domestic industries from unfair competition caused by foreign imports sold at below fair market value. The Customs and Tariff Bureau (Zei Kanri Kyoku) is responsible for implementing and enforcing these regulations. The guidelines were first established in 2001 and have undergone several revisions to adapt to changing trade dynamics and international agreements. The most recent amendments, announced in April 2026, reflect Japan’s commitment to maintaining fair trade practices while ensuring compliance with World Trade Organization (WTO) standards. These changes include clearer definitions of what constitutes dumping, streamlined procedures for filing complaints, and enhanced transparency in the investigation process.How This Affects Your Business in Japan

If you are currently importing goods, it is crucial to review your pricing strategies to ensure compliance with the updated anti-dumping regulations.
