Tokugawa Ieshige
Shigemura was the second son of Date Munemura. His infant name was Gihachirō (儀八郎), and he was renamed Date Kunimura on the death of his elder brother in 1745. At the time of his "genpuku" ceremony in 1755, he received a "kanji" from "Shōgun" Tokugawa Ieshige and thus became Date Shigemura. He became "daimyō" at the age of 15 the following year, on the death of his father. Due to his youth, the shogunate appointed his uncle, Tamura Murataka of Ichinoseki Domain as his guardian. He inherited a dire situation, in which the domain was suffering from a great famine, finances were in arrears, and there was bitter in-fighting between the various senior retainers.
