After the defeat of the Kwantung Army in Manchuria, Japanese POWs were sent from Manchuria, Korea, South Sakhalin and Kuril Islands to Primorski Krai, Khabarovsk Krai, Krasnoyarsk Krai, Kazakhstan (South Kazakhstan Province and Zhambyl Province), Buryat-Mongol ASSR, and Uzbek SSR. In 1946, 49 labor camps for Japanese POWs under the management of GUPVI housed about 500,000 persons. In addition there were two camps for those convicted of various crimes. Prisoners were grouped into 1,000 person units. Some male and female Japanese civilians, as well as Koreans were also imprisoned when there were not enough soldiers to fill a unit.
