The Ochi-Matsudaira clan was founded by Matsudaira Kiyotake, the younger brother of the 6th shōgun Tokugawa Ienobu. The Ochi-Matsudaira ruled the Hamada Domain. The family lost most of its territory in 1866, when the castle town was occupied by Chōshū Domain forces under Ōmura Masujirō during the Chōshū War. Matsudaira Takeakira, the last "daimyō", escaped Hamada and went to Tsuruta, one of the domain's non-contiguous territories; there he set up the Tsuruta Domain, which existed until the abolition of the domains in 1871. In the Meiji era, Takeakira's son Matsudaira (Ochi) Takenaga received the title of viscount.
