Background & Context
The NACCS (Nippon Automated Cargo and Port Consolidated System) is a critical system used by Japan Customs to streamline the import and export process. The introduction of new item codes on April 1, 2026, is part of Japan’s ongoing efforts to enhance trade efficiency and compliance with international standards. The current legal framework governing customs in Japan is primarily outlined in the Customs Act (Kanzei-hō) of 2018, which has undergone several amendments to adapt to changing global trade dynamics. The new item codes will replace existing classifications, necessitating updates in documentation and processes for businesses engaged in trade. The Japan Customs (Nihon Zeikan) is responsible for implementing these changes, and foreign businesses must stay informed to ensure compliance with the updated regulations. The timeline for these changes has been communicated through official channels, and businesses should begin preparing for the transition well in advance of the effective date.How This Affects Your Business in Japan

Consult with legal and trade experts to ensure your business plan aligns with the new regulations. Prepare to submit necessary documentation that reflects the updated item codes upon your company’s launch.
3. Foreign Investors Who Are NOT Residents of Japan
If you are considering investing in Japanese businesses that engage in trade, it is crucial to understand how the new NACCS item codes will affect their operations.
