Domestic security in Japan is provided mainly by the prefectural police departments, under the oversight of the National Police Agency. As the central coordinating body for the Prefectural Police Departments, the National Police Agency is administered by the National Public Safety Commission. The Special Assault Team comprises national-level counter-terrorism tactical units that cooperate with territorial-level Anti-Firearms Squads and Counter-NBC Terrorism Squads. The Japan Coast Guard guards territorial waters surrounding Japan and uses surveillance and control countermeasures against smuggling, marine environmental crime, poaching, piracy, spy ships, unauthorized foreign fishing vessels, and illegal immigration.
