The National Police Agency (警察庁 Keisatsuchō) is the central coordinating body of the Japanese police system.
Unlike comparative bodies like the US Federal Bureau of Investigation, the NPA does not have any police officers of its own. Instead, its role is to determine general standards and policies, although in national emergencies or large-scale disasters the agency is authorized to take command of prefectural police forces. Policy for the NPA in turn is set by the National Police Safety Commission.
