The Soviet invasion of Manchuria, formally known as the Manchurian Strategic Offensive Operation or simply the Manchurian Operation (Маньчжурская операция) and sometimes Operation August Storm, began on 9 August 1945 with the Soviet invasion of the Empire of Japan's puppet state of Manchukuo, which was situated in Japanese-occupied Manchuria. It was the largest campaign of the 1945 Soviet–Japanese War, which resumed hostilities between the Union of Soviet Socialist Republics and the Empire of Japan after almost six years of peace.
Soviet gains on the continent were Manchukuo, Mengjiang (the northeast section of present-day Inner Mongolia) and northern Korea. The Soviet entry into this theater of the war and the defeat of the Kwantung Army were significant factors in the Japanese government's decision to surrender unconditionally, as it became apparent that the Soviet Union had no intention of acting as a third party in negotiating an end of the war on conditional terms.
