Edo Neo-Confucianism, known in Japanese as Shushi-Gaku (朱子学 shushigaku?), refers to the schools of Neo-Confucian philosophy that developed in Japan during the Edo period. Neo-Confucianism reached Japan during the Kamakura period. The philosophy can be characterized as humanistic and rationalistic, with the belief that the universe could be understood through human reason, and that it was up to man to create a harmonious relationship between the universe and the individual.
