Kempeitai
Imperial Japanese military police
The Kempeitai (Japanese: 憲兵隊, Hepburn: Kenpeitai; lit. 'Corps of Law Soldiers') was the military police of the Imperial Japanese Army (IJA). The organization also shared civilian secret police and gendarmerie responsibilities. At its peak at the end of World War II, the Kempeitai had about 35,000 personnel, or kempei (憲兵).
Founded in 1881 during the Meiji era, the Kempeitai was based on France's National Gendarmerie. The broad duties of the Kempeitai included maintaining military discipline, enforcing conscription laws, protecting vital military zones, and investigating crimes among soldiers. Institutionally part of the Army, the Kempeitai also discharged limited military police functions for the Imperial Japanese Navy (IJN).
As Japanese militarism expanded, so did the Kempeitai's ranks and duties.
During World War II, the organization ran Japan's prisoner-of-war camps and civilian internment camps, and were known for their mistreatment of detainees. They also provided security at important government and military locations at risk of being sabotaged within the Empire of Japan and its occupied territories.
It also procured comfort women as well as human test subjects for Unit 731.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
