Yashima Domain

Yashima Domain (矢島藩, Yashima-han^?) was a feudal domain in Edo period Japan, located in Dewa Province (modern-day Akita Prefecture), Japan. It was centered on Yashima Jin'ya in the former town of Yashima, Akita, in what is now part of the city of Yurihonjō, Akita.

The Ikoma clan was originally a powerful 171,800 koku daimyo clan ruling Takamatsu Domain in Sanuki Province. However, the Ikoma were dispossessed in 1640 due to gross mismanagement by Ikoma Takatoshi which resulted in an O-Ie Sōdō by his retainers. The Tokugawa shogunate reassigned the clan to the newly created 10,000 koku Yashima Domain in the inhospitable foothills of Mount Chōkai in central Dewa Province, where Ikoma Takatoshi was ordered to remain under house arrest for over 20 years. Furthermore, in 1659 his son and heir Ikoma Takakiyo was forced to divide 2000 koku of his inheritance to a younger brother, and thus the clan lost its status as a daimyo clan, and was reduced to the ranks of the hatamoto.
