The Japanese were very brutal toward the people in East Asia that they conquered. Similar to the Germans, and even worse in certain aspects, the Japanese treated the conquered people as lower human beings, as not worth of living, as primitive. The rate of sexual assaults that happened was extremely high. People were tortured, murdered for no reason, and used as slaves.
