Hayashi clan (Confucian scholars)

The Hayashi clan (林氏, Hayashi-shi) was a Japanese samurai clan which served as important advisors to the Tokugawa shōguns. Among members of the clan in powerful positions in the shogunate was its founder Hayashi Razan, who passed on his post as hereditary rector of the neo-Confucianist Shōhei-kō school to his son, Hayashi Gahō, who also passed it on to his son, Hayashi Hōkō; this line of descent continued until the end of Hayashi Gakusai's tenure in 1867.
