Confucianism began to be recognized as the learning essential to daimyo in the Muromachi period. When Genju Keian, who returned from the Ming dynasty, traveled around Kyushu, he was invited by the Kikuchi clan in Higo Province and the Shimazu clan in Satsuma Province to give a lecture; and later, he established the Satsunan school (school of Neo-Confucianism in Satsuma). In Tosa, Baiken Minamimura, who lectured on Neo-Confucianism, became known as the founder of Nangaku (Neo-Confucianism in Tosa); in Hokuriku region, Nobutaka Kiyohara lectured on Confucianism for various daimyo such as the Hatakeyama clan in Noto Province, the Takeda clan in Wakasa Province, and the Asakura clan in Echizen Province.
