Iida Domain

Iida Domain (飯田藩, Iida-han^?) was a feudal domain under the Tokugawa shogunate of Edo period Japan. It is located in Shinano Province, Honshū. The domain was centered at Iida Castle, located in what is now part of the town of Iida in Nagano Prefecture. It was also known as Shinano-Iida Domain (信濃飯田藩, Shinano-Iida-han^?).

The area around Iida had been ruled during the Sengoku period by Akiyama Nobutomo, a retainer of Takeda Shingen. After the destruction of the Takeda clan, the lands came under the control of Tokugawa Ieyasu and were ruled by Suganuma Sadatoshi, followed by Mori Hideyori, and Kyōgoku Takatomo. Following the Battle of Sekigahara and the establishment of the Tokugawa shogunate, Ogasawara Hidemasa was relocated to Iida from Koga Domain in Shimōsa Province and made daimyō with Iida Domain, a 50,000 koku holding in Shinano Province. After his transfer to Matsumoto Domain in 1613, the territory reverted to tenryō status ruled directly by the shogunate until 1617, when it was reassigned to Wakizaka Yasumoto, formerly of Ōzu Domain in Iyo Province. His son, Wakizaka Yasumoto followed, reducing the domain by 2,000 koku with a gift to one of his uncles. He was transferred to Tatsuno Domain in Harima Province in 1672, where his descendants resided to the Meiji restoration.
