The Counterinsurgency in Manchuria was a Japanese counterinsurgency campaign to suppress any armed resistance to the newly established puppet state of Manchukuo from various anti-Japanese volunteer armies in occupied Manchuria and later the communist Northeast Anti-Japanese United Army. The operations were carried out by the Imperial Japanese Kwantung Army and the collaborationist forces of the Manchukuo government from March 1932 until 1942, and resulted in a Japanese victory.
