Amendments to Import Customs Procedures for Marine Animals under the Fisheries Resource Protection Act

On May 29, 2026, Japan implemented important amendments to the import customs procedures for marine animals under the Fisheries Resource Protection Act (Suisan Shigen Hogo Ho). These changes are critical for foreign businesses involved in marine imports, affecting compliance and operational processes. Understanding these regulations is essential to ensure compliance and navigate Japan’s customs system effectively.

Background & Context

The Fisheries Resource Protection Act (Suisan Shigen Hogo Ho) is designed to regulate the conservation and sustainable use of marine resources in Japan. The recent amendments, effective from May 29, 2026, introduce new compliance measures for importers, focusing on documentation and handling of protected marine species. This update aligns with international standards, including commitments under CITES. The Ministry of Finance (Zaimu-sho) and Japan Customs (Nihon Zeikan) oversee these regulations, enhancing monitoring of marine imports to ensure sustainable sourcing. Importers must stay informed to avoid penalties and ensure smooth customs clearance.

1. Foreign Residents Already Operating a Business in Japan
If you are currently importing marine animals, familiarize yourself with the new documentation requirements, including obtaining a Certificate of Origin and ensuring all marine species are correctly listed in your import declaration. Non-compliance could lead to delays or fines. Consult with a customs broker to navigate these changes and update your import documentation by May 29, 2026, to avoid disruptions.

2. Foreign Nationals Planning to Establish a New Company
If planning to start a business involving marine imports, integrate these regulations into your business plan. Secure necessary permits and ensure compliance with the Fisheries Resource Protection Act from the outset. Liaise with local authorities and consider hiring legal counsel for compliance assistance. Begin this process early to ensure readiness by the effective date.

3. Foreign Investors Who Are NOT Residents of Japan
Understanding these regulations is crucial if you plan to invest in businesses dealing with marine imports. Conduct thorough due diligence on potential investments to ensure compliance. Engage with local partners experienced in navigating Japan’s customs landscape. Delays in compliance can lead to financial losses, so act promptly and seek expert advice.
