It was notorious for its brutality and role in suppressing dissent. The broad duties of the ''Kempeitai'' included maintaining military discipline, enforcing conscription laws, protecting vital military zones, and investigating crimes among soldiers. In occupied areas, it also issued travel permits, recruited labor, arrested resistance, requisitioned food and supplies, spread propaganda, and suppressed anti-Japanese sentiment. At its peak at the end of World War II, the ''Kempeitai'' had about 35,000 personnel.

Founded in 1881 during the Meiji era, the size and duties of the ''Kempeitai'' grew rapidly as Japanese militarism expanded. During World War II, the organization ran Japan's prisoner of war and civilian internment camps, known for their mistreatment of detainees, and also acted as a political police force in the military and occupied territories. It carried out torture, summary executions, and violent reprisals and massacres against civilians, as well as procuring comfort women and human test subjects for Unit 731. The ''Kempeitai'' was disbanded after the war, and many of its leaders were tried and convicted of war crimes. While institutionally part of the Army, the ''Kempeitai'' also discharged limited military police functions for the Imperial Japanese Navy (IJN). A member of the ''Kempeitai'' corps was called a ''kempei'' . The ''Kempeitai'' was based on France's National Gendarmerie. Provided by Wikipedia
