O-Ie Sōdō
was the 1st Itakura "daimyō" of Fukushima Domain. He was the eldest son of Itakura Shigetane, the "daimyō" of Sakaki Domain in Shinano Province. His wife was the daughter of Mizuno Tadanao of Matsumoto Domain. Due to an "O-Ie Sōdō" in 1683, Shōgun Tokugawa Tsunayoshi forced Shigetane to retire and divided Sakaki Domain between his two sons, with 30,000 "koku" to Shigehiro and the remaining 20,000 "koku" to Shigehiro’s younger brother Shigenobu. In 1702, Shigehiro was transferred to Fukushima Domain. He retired in 1717 and died in 1721 at the age of 53.
