The army was formed on the Kwantung Peninsula in 1931. Initially, its number was about 15 thousand people. Here saboteurs were trained for operations against the Soviet Union and Mongolia. In 1938, more than 200 thousand Japanese served in the Kwantung Army.
Operation Nekka against the troops of the Chinese Republic lasted from January to May 1933. It ended with the truce of Tangu - a zone south of the Great Wall of China with a length of 100 kilometers was declared demilitarized. Japan received the right to reconnaissance flights over this zone.

In 1945, the Japanese sabotage forces resisted most stubbornly against the offensive of the Soviet troops. The soldiers shot the officers who ordered them to surrender. Detachments of suicide bombers committed acts of terrorism against Soviet soldiers, destroyed equipment in the rear. The disarmament of the Japanese troops lasted from August 19 to September 2, 1945. Separate units of the Kwantung Army resisted Soviet troops until September 10. The commander-in-chief of the army, General Otozo Yamada, was captured and was sentenced by the Military Tribunal of the Primorsky Military District to 25 years in prison. In 1956, Yamada was pardoned.
