Tokugawa Ieharu
On September 18, 1781, "Shōgun" Tokugawa Ieharu, at the recommendation of his senior councilor Tanuma Okitsugu granted a 3000 "koku" holding in southern Awa Province to his page Inaba Masaaki, which, when added to his existing 2000 "koku" in Awa, and 5000 "koku" in Kazusa and Hitachi provinces, raised him to the status of a daimyō. He rebuilt Tateyama Castle, and his descendants ruled over the revived Tateyama Domain until the Meiji Restoration.
