Shimodate Domain

The Mizunoya later became independent under Toyotomi Hideyoshi, and although under strong pressure from Ishida Mitsunari and the western daimyō, pledged allegiance to Tokugawa Ieyasu during the Battle of Sekigahara, and were reconfirmed in their 31,000 koku holdings under the Tokugawa shogunate.

Mizutani Katsutaka laid out the foundations of the castle town and built a number of temples before the clan was transferred to Nariwa Domain in Bitchu Province.

He was replaced by Inoue Masamine, who had served as a wakadoshiyori, but he held the post for less than a month before moving to Kasama Domain in Hitachi Province.

The final daimyō, Ishikawa Fusakane, served as wakadoshiyori and Rikugun bugyo under the Tokugawa shogunate and helped suppress the Tenchu revolt; however, during the Boshin War, he switched sides to the Imperial cause.

[1] As with most domains in the han system, Shimodate Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.
