Tahara Domain

Tahara Domain (田原藩, Tahara-han^?) was a minor fudai Japanese domain under the Tokugawa shogunate of Edo period Japan, located in southern Mikawa Province (modern-day southeastern Aichi Prefecture), Japan. It was centered on Tahara Castle in what is now the city of Tahara.

Most of the Atsumi Peninsula was controlled by the Toda clan during the Muromachi and Sengoku periods. The Toda pledged loyalty to the Imagawa clan, but later came under the rule of the Tokugawa clan. Following the Battle of Odawara in 1590, Toyotomi Hideyoshi assigned the Kantō region to Tokugawa Ieyasu and the Toda were dispossessed of their holdings, which were given to Hideyoshi's vassal, Ikeda Terumasa. The Toda accompanied Ieyasu to Edo and were reduced in status to hatamoto with a minor 5000 koku holding in Shimoda in Izu Province.
