Sadao Araki (荒木 貞夫, Araki Sadao, May 26, 1877 – November 2, 1966) was a general in the Imperial Japanese Army before and during World War II. As one of the principal nationalist right-wing political theorists in the Empire of Japan, he was regarded as the leader of the radical faction within the politicized Imperial Japanese Army and served as Minister of War under Prime Minister Inukai. He later served as Minister of Education during the Konoe and Hiranuma administrations.
