# National Police Agency (Japan)

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.

## History

Police services of the Empire of Japan were placed under complete centralized control with the Police Affairs Bureau [ja] (警保局, 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.
During the occupation, the principle of decentralization was introduced by the 1947 Police Law. Cities and large towns had their own municipal police services (自治体警察, Jichitai Keisatsu), and the National Rural Police [ja] (国家地方警察, Kokka Chihō 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.
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 for each prefecture, and the National Police Agency was established as the central coordinating agency for these Police Departments.
On April 1, 2022, the NPA created the Cyber Affairs Bureau and the National Cyber Unit. In December 2023, the NPA announced that the TAIT (Telecom Scam Allianced Investigation Team) will be established in April 2024 to unify investigation efforts across Japan on fraud cases.

## Organization
