born Jan. 24, 1619, Kyōto, Japan
died Oct. 16, 1682, Kyōto
Japanese exponent of the philosophy of the Chinese Neo-Confucianist Zhu Xi .
Early in life he was a Buddhist monk, but he gradually rejected Buddhism in favour of Confucianism, which he began to teach to thousands of students. He reduced Neo-Confucianism to a simple moral code, which he then blended with native Shintō religious doctrines. He equated Neo-Confucian principles and theories with Shintō legends and divinity, creating a philosophical system that took on greater authority than its sources possessed alone. His thought was one of the sources of the extreme nationalism and emperor worship that developed later in Japan.
