Following the reassignment of the Tokugawa clan to Shizuoka Domain, he was transferred to the newly-created Kikuma Domain in Kazusa Province with the same nominal kokudaka and his courtesy title was changed to Ugo-no-kami. he was appointed imperial governor of Kikuma until the abolition of the han system in 1871. In July 1884, he received the peerage title of viscount (shishaku) under the kazoku peerage system. He died in 1907 and his grave is at the Denzu-in in Bunkyo, Tokyo. His wife was the third daughter of Ōkōchi Masatomo, daimyō of Ōtaki Domain
