On September 18, 1781, ShōgunTokugawa Ieharu, at the recommendation of his senior councilor Tanuma Okitsugu granted a 3000 koku holding in southern Awa Province to his pageInaba 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.
During the Bakumatsu period, Inaba Masami served in several important posts within the administration of the Tokugawa shogunate. However, with the Boshin War, he went into retirement, and his successor Inaba Masayoshi, pledged loyalty to the new Meiji government. However, in response, the Tokugawa navy, under Enomoto Takeaki invaded Tateyama, and used it as a base to attack Satchō Alliance forces in Kazusa Province. After the end of the conflict, with the abolition of the han system in July 1871, Tateyama Domain became Tateyama Prefecture, which merged with the short-lived
Kisarazu Prefecture in November 1871, which later became part of Chiba Prefecture.
The domain had a population of 23,202 people in 3526 households per a census in 1869.[1]
Holdings at the end of the Edo period
As with most domains in the han system, Tateyama Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.[2][3]
