The women in South Korea who served as prostitutes are known as kijichon (기지촌) women, also called as "Korean Military Comfort Women", and were visited by the U.S. military, Korean soldiers and Korean civilians. Kijich'on women were from Korea, Philippines, China, Vietnam, Thailand, Sri Lanka, Nepal, Indonesia and the Commonwealth of Independent States, specifically Russia and Kazakhstan.
