林羅山
(also known as "Hayashi Fukusai") was an Edo period scholar-diplomat serving the Tokugawa shogunate in a variety of roles similar to those performed by serial Hayashi clan neo-Confucianists since the time of Tokugawa Ieyasu. He was the hereditary "Daigaku-no-kami" descendant of Hayashi Razan, the first head of the Tokugawa shogunate's neo-Confucian academy in Edo, the "Shōhei-kō" ("Yushima Seidō").
