Hayashi Razan
In 1632, Tokugawa Yoshinao, the 9th son of Tokugawa Ieyasu and "daimyō" of Owari Domain was granted permission to build an academy in Edo for the study and propagation of Confucianism. The first structure, the Sensei-den (先聖殿), constructed by the neo-Confucian scholar Hayashi Razan (1583–1657) in his grounds at Shinobu-ga-oka (now in Ueno Park). Under succeeding generations of Tokugawa shoguns and under the leadership of the Hayashi clan, Japanese Neo-Confucianism, particularly as developed in the teachings of Zhu Xi became the official orthodoxy and basis of the political philosophy of the Tokugawa shogunate.
