It was both a conventional military police and a secret police force. In Japanese-occupied territories, the kenpeitai also arrested those who were suspected of being anti-Japanese. While it was institutionally part of the army, the Kenpeitai also discharged the functions of the military police for the Imperial Japanese Navy under the direction of the Admiralty Minister (although the IJN had its own much smaller Tokkeitai), those of the executive police under the direction of the Home Minister and those of the judicial police under the direction of the Justice Minister.
