The japanese would take Korean women specifically and enslave them as sex slaves for the soldiers. They would transport them around Asia/Southeast Asia wherever the Japanese soldiers were at, setting up brothel houses. The Japs favored them I think for their lighter skin tone, not sure. Truly horrific shit that went on over there. I am sure you Mother in Law is a true character with a lot of stories.Koreans are tougher. I have personal knowledge of this.
