The National Police Agency (Japanese: 警察庁, Hepburn: Keisatsu-chō) is the central coordinating law enforcement agency of the Japanese police system. Unlike national police in other countries, the NPA does not have any operational units of its own aside from the Imperial Guard; rather, it is responsible for supervising Japan's 47 prefectural police departments and determining their general standards and policies, though it can command police agencies under it in national emergencies or large-scale disasters. It is under the National Public Safety Commission of the Cabinet Office.
As of 2017, the NPA has a strength of approximately 7,800 personnel: 2,100 sworn officers, 900 guards, and 4,800 civilian staff.
