Tokugawa Munekatsu (徳川 宗勝, 1705–1761) was a Japanese daimyō of the Edo period.[1] He ruled the Takasu Domain in Mino, and later succeeded his cousin Tokugawa Muneharu, who had been placed under house arrest, to become eighth Tokugawa lord of the Owari Domain in Nagoya.[1] In that capacity, Munekatsu enacted political reforms that reversed the extravagances of his predecessor, Muneharu.[2]
As lord of Takasu he used the name Matsudaira Yoshiatsu (松平 義淳).[citation needed] His other names were Tomosuke (友相) and Tomoatsu (友淳).[1]
