The National Police Agency (, Keisatsu-ch?) is an agency administered by the National Public Safety Commission of the Cabinet Office of the Cabinet of Japan, and is the central agency of the Japanese police system, and the central coordinating agency of law enforcement in situations of national emergency in Japan.

Unlike comparable bodies such as the U.S. Federal Bureau of Investigation, the NPA does not have any operational units of its own except for the Imperial Guard. Instead, its role is to supervise Prefectural police departments and determine general standards and policies; although in national emergencies or large-scale disasters the agency is authorized to take command of Prefectural police departments.

As of 2017, the NPA has a strength of approximately 7,800 personnel: 2,100 sworn officers, 900 guards and 4,800 civilian staff.[2]


Police services of the Empire of Japan were placed under complete centralized control with the Police Affairs Bureau (, Keiho-kyoku) of the Home Ministry at their core. But after the surrender of Japan, the Supreme Commander for the Allied Powers regarded this centralized police system as undemocratic.[3]

During the Occupation, the principle of decentralization was introduced by the 1947 Police Law. Cities and large towns had their own municipal police services (, Jichitai Keisatsu), and the National Rural Police (, Kokka Chih? Keisatsu) was responsible for smaller towns, villages and rural areas. But most Japanese municipalities were too small to have a large police force, so sometimes they were unable to deal with large-scale violence. In addition, excessive fragmentation of the police organization reduced the efficiency of police activities.[3]

As a response to these problems, complete restructuring created a more centralized system under the 1954 amended Police Law. All operational units except for the Imperial Guard were reorganized into prefectural police departments for each prefecture, and the National Police Agency was established as the central coordinating agency for these Police Departments.[3]



The Commissioner General of the National Police Agency (, Keisatsu-ch? Ch?kan) is the highest ranking police officer of Japan, regarded as an exception to the regular class structure. For the Deputy Commissioner General (, Jich?), the Senior Commissioner is supplemented. The Commissioner General's Secretariat (?, Ch?kan Kanb?) are their staff. The civilian political leadership is provided by the National Public Safety Commission.[3]

Metropolitan Tokyo and the island of Hokkaid? are excluded from the regional jurisdictions and are run more autonomously than other local forces, in the case of Tokyo, because of its special urban situation, and of Hokkaid?, because of its distinctive geography. The National Police Agency maintains police communications divisions in these two areas to handle any coordination needed between national and local forces. In other area, Police Communications Departments are established within each Regional Police Bureaus.
