Tokugawa Mitsukuni
Tokugawa Mitsukuni, the third son of Tokugawa Yorifusa, became the second "daimyō" of Mito in 1661. Mitsukuni further established Mito's status as a respected han by sponsoring the "Dai Nihon-shi" in 1657. The endeavor would launch Mito's reputation as a center for intellectual thought.
