Hayashi Gahō (林 鵞峰; July 21, 1618 – June 1, 1680), also known as Hayashi Shunsai|林 春斎|, was a Japanese Neo-Confucian philosopher and writer in the system of higher education maintained by the Tokugawa bakufu during the Edo period. He was a member of the Hayashi clan of Confucian scholars. Following in the footsteps of his father, Hayashi Razan, Gahō (formerly Harukatsu) would devote a lifetime to expressing and disseminating the official neo-Confucian doctrine of the Tokugawa shogunate. Like his distinguished father, Gahō's teaching and scholarly written work emphasized Neo-Confucianist virtues and order. Source: Wikipedia (en)
