Moriyama Domain

Moriyama Domain (守山藩) was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in southern Mutsu Province in what is now part of the modern-day city of Kōriyama, Fukushima. It was established by a cadet branch of the Tokugawa clan of Mito. A relatively small domain, it had a kokudaka of 20,000 koku.

History
In 1661, Matsudaira Yorifusa of Mito Domain created Nukada Domain, 20,000 koku subsidiary holding for his fourth son, Matsudaira Yorimoto in what is now part of the city of Naka, Ibaraki. He ruled Nukata until his death in 1693, and was succeeded by his son, Matsudaira Yorisada. By order of Shōgun Tokugawa Tsunayoshi, Yorisada was granted a fief of 20,000 koku in Moriyama in Tamura District in Mutsu Province in 1700. His original holdings reverted to Mito Domain. Although the daimyō of Moriyama were not subject to sankin-kōtai since they were direct relatives of the ruling Tokugawa, they preferred to reside permanently at the clan's Edo residence in Koishikawa and to leave administration of the domain in the hands of overseers appointed by the parent house at Mito Domain. During the Bakumatsu period, many of the samurai of Moriyama supported the Mito Rebellion of 1864, and the clan was punished by the shogunate. When the forces of the anti-Tokugawa Satchō Alliance advanced north during the Boshin War, the domain surrendered without a fight.

Following the Meiji restoration, the seat was of the domain was transferred to what is now Ōarai, Ibaraki and it was briefly renamed Matsukawa Domain from 1868 until the abolition of the han system in 1871. Matsudaira Yoriyuki, the last daimyō of Moriyama, was succeeded by Matsudaira Nobunori, the adopted former lord of Aizu who had cut his familial ties to Matsudaira Katamori as imperial governor of Matsukawa..

Holdings at the end of the Edo period
As with most domains in the han system, Moriyama Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.
