Japanese philosopher considered to be one of the forerunners of the 19th-century movement to restore power to the emperor. He was also one of the first Japanese to study European thought.

Andō was a native of Akita. He practiced medicine at Hachinohe, in the present Aomori prefecture, but became prominent as a social thinker in the 1750s. Andō was critical of the feudal society of the Tokugawa shogunate. In his work Shizen shin'eidō (“The True Way of Administering 【the society】 According to Nature”), he called for the abolition of the warrior class and a return to agrarian egalitarian society, which was to be administered directly by the national government.
