who's side was japan on in ww1
Japan during World War I Japan participated in World War I from 1914 to 1918 in an alliance with Entente Powers and played an important role in securing the sea lanes in the West Pacific and Indian Oceans against the Imperial German Navy as the member of the Allies. Politically, Japanese Empire seized the opportunity to expand its sphere of influence in China, and to gain recognition as a great power in postwar geopolitics.
Soviet–Japanese War The Soviet–Japanese War (Russian: Советско-японская война; Japanese: ソ連対日参戦, "Soviet Union entry into war against Japan") was a military conflict within the Second World War beginning soon after midnight on August 9, 1945, with the Soviet invasion of the Japanese puppet state of Manchukuo. The Soviets and Mongolians terminated Japanese control of Manchukuo, Mengjiang (Inner Mongolia), northern Korea, Karafuto, and the Chishima Islands. The defeat of Japan's Kwantung Army helped in the Japanese surrender and the termination of World War II.[7][8] The Soviet entry into the war was a significant factor in the Japanese government's decision to surrender unconditionally, as it made apparent the Soviet Union would no longer be willing to act as a third party in negotiating an end to hostilities on conditional terms.[1][9][10][11][12][13][14][15]
