To prevent venereal diseases and rape by Japanese soldiers and to provide comfort to soldiers and head off espionage, the Imperial Japanese Army established "comfort stations" in the Greater East Asia Co-Prosperity Sphere where around 200,000 women, mostly from Korea and China, were recruited or kidnapped by the Kempeitai or the Tokeitai as comfort women.
