Background & Context

The Japanese import declaration process is governed by the Customs Act (Kanzei-hō) and related regulations. The current framework allows for a preliminary review system that determines whether customs inspections are necessary based on the manifest submitted by importers. This system aims to facilitate smoother import operations while ensuring compliance with customs regulations. Historically, the preliminary review system has undergone several amendments to enhance efficiency and reduce delays in the import process. The upcoming changes, effective from July 19, 2026, are expected to refine the notification timing regarding the necessity of customs inspections, which will help businesses better plan their import activities. The Japanese Customs (Zei-kan) has been proactive in updating these regulations to adapt to the evolving global trade environment and to support foreign businesses operating in Japan.
