Kaminoyama Domain

Kaminoyama Domain (上山藩, Kaminoyama han^?) a feudal domain in Edo period Japan, located in Dewa Province (modern-day Yamagata Prefecture), Japan. It was centered on Kaminoyama Castle in what is now the city of Kaminoyama, Yamagata.

Kaminoyama Domain was situated on the strategic Ushū Kaidō, subroute of the Ōshū Kaidō connecting Edo with the northern portion of Honshu. The domain was sandwiched in between the powerful Yamagata Domain to the north and the Yonezawa Domain to the south.

During the Muromachi period, the area was noted as a hot spring resort and a stronghold of the Mogami clan. It was a contested territory between the Mogami and the Date clans during the Sengoku period, and later between the Mogami and the Uesugi clan. After the destruction of the Mogami clan by the Tokugawa shogunate, Kamiyama Domain (40,000 koku) was created in 1622 for Matsudaira Shigetada, who laid out the plan of the future castle town. The Matsudaira were replaced by the Gamō clan from 1626-1627, followed by the Toki clan from 1628-1691, and the Kanemori clan from 1692-1697. Kaminoyama Domain was then ruled by the Fujii branch of the Matsudaira clan from 1698 until the Meiji restoration. The domain had 2200 households per the 1852 census and maintained its primary Edo residence (kamiyashiki) in Azabu. The clan’s Edo temple was Tessho-ji in Nishi-Asakusa.
