Kwantung ArmyThe Kwantung Army (Japanese: 関東軍, Kantō-gun) was a general army of the Imperial Japanese Army from 1919 to 1945. The Kwantung Army formed in 1906 as a security force for the Kwantung Leased Territory and South Manchurian Railway Zone after the Russo-Japanese War of 1904–1905, and expanded into an army group during the Interwar period to support Japanese interests in China, Manchuria, and Mongolia.
Hakkō ichiu"eight crown cords, one roof", i.e. "all the world under one roof" or hakkō iu (Shinjitai: 八紘為宇, 八紘爲宇) was a Japanese political slogan meaning the divine right of the Empire of Japan to "unify the eight corners of the world." The slogan formed the basis of the empire's ideology. It was prominent from the Second Sino-Japanese War to World War II and was popularized in a speech by Prime Minister Fumimaro Konoe on January 8, 1940.
KantokuenKantokuen (関特演, from 関東軍特種演習, Kantōgun Tokushu Enshū, "Kwantung Army Special Maneuvers") was an operational plan created by the General Staff of the Imperial Japanese Army for an invasion and occupation of the Russian Far East, capitalizing on the outbreak of the Soviet-German War in June 1941. Involving seven Japanese armies and a major portion of the empire's naval and air forces, it would have been the largest combined arms operation in Japanese history up to that point, and one of the largest of all time.
February 26 incidentThe February 26 incident was an attempted coup d'état in the Empire of Japan on 26 February 1936. It was organized by a group of young Imperial Japanese Army (IJA) officers with the goal of purging the government and military leadership of their factional rivals and ideological opponents. Although the rebels succeeded in assassinating several leading officials (including two former prime ministers) and in occupying the government center of Tokyo, they failed to assassinate Prime Minister Keisuke Okada or secure control of the Imperial Palace.
