Background & Context

Japan’s customs regulations are governed by the Customs Act (Zeikan-ho), which outlines the procedures for import and export activities. The preliminary review system allows for a more efficient customs process by enabling importers to receive advance notifications regarding the necessity of customs inspections. This system has been in place to streamline the import process, but recent revisions aim to enhance its effectiveness. The latest update, announced by the Japan Customs Authority (Nihon Zeikan), focuses on the timing of notifications concerning the need for customs inspections during manifest declarations. This change is part of a broader effort to improve the efficiency of customs operations and reduce delays in the import process. The revisions are expected to take effect in the coming months, with specific implementation dates to be confirmed. This is particularly relevant for foreign entrepreneurs who must navigate these regulations to ensure compliance and avoid potential penalties.
