Yoshida Domain

Yoshida Domain (吉田藩, Yoshida-han^?) was a Japanese feudal domain under the Tokugawa shogunate of Edo period Japan, located in Mikawa Province located in eastern Mikawa Province (modern-day eastern Aichi Prefecture), Japan. It was centered on Yoshida Castle in what is now the city of Toyohashi, Aichi. It was ruled by a number of different fudai daimyō over the course of the Edo period, before finally passing into the hands of the Matsudaira (Ōkōchi) clan. Just before its dissolution it was renamed, and it became the Toyohashi Domain (豊橋藩, Toyohashi-han^?).

Following the Battle of Odawara in 1590, Toyotomi Hideyoshi transferred Tokugawa Ieyasu to the Kantō region, and gave a portion of his former territories in eastern Mikawa to Ikeda Terumasa. Terumasa developed the castle town around Yoshida Castle and embarked on a massive and ambitious expansion plan for the castle itself. However, following the Battle of Sekigahara, he was reassigned to Himeji Castle, and left Yoshida even before a central donjon had been completed.
