Hunchun incident

The Hunchun incident (Korean: 훈춘 사건; Hanja: 琿春事件) was a reported raid on 2 October 1920 at a Japanese consulate in Manchuria. It reportedly resulted in the death of thirteen Japanese. The Japanese government used this incident to justify sending thousands of Imperial Japanese troops into Manchuria on 5 October 1920. These escalations culminated with the Battle of Qingshanli (21–26 October 1920) between Japan and the Korean Independence Army, where Korean rebels fought Japanese soldiers.
