Background & Context
Japan’s customs regulations are governed by the Customs Act (Kanzei-hō), which outlines the legal framework for import and export activities. In recent years, the Japanese government has focused on strengthening enforcement mechanisms to combat tariff violations, reflecting a global trend towards stricter trade compliance. The National Tax Agency (Kokuzei-chō) and the Japan Customs (Nihon Zeikan) have reported a significant increase in the number of investigations and penalties imposed on businesses that fail to adhere to tariff regulations. In 2025, amendments to the Customs Act were introduced to enhance the penalties for violations, which has led to a more vigilant enforcement environment. The first half of 2026 has seen a continuation of this trend, with customs authorities conducting thorough inspections and audits to ensure compliance. Foreign entrepreneurs must be aware of these developments to avoid potential legal issues and financial penalties.How This Affects Your Business in Japan
