Biography.
Narimura was the second son of Date Shigemura by a concubine. His childhood name was Shikisaburo (式三郎) later Shojiro (総次郎) later become Date Tokimura, and he became heir on the death of his elder brother in 1783. At the time of his "genpuku" ceremony in 1787, he received a "kanji" from "Shōgun" Tokugawa Ienari and became Date Narimura. He also received court rank of Junior Fourth, Lower Grade and the courtesy titles of "Mimasaka-no-kami" and "Jijū" (chamberlain) at that time. In 1790, he became "daimyō" on the retirement of his father, and his title was changed to "Mutsu-no-kami" and "Sakonoe-shōshō". In 1793, he married the daughter of the "kampaku" Takatsukasa Sukehira, who was the elder sister of Emperor Kōkaku. 
The year 1796 was not a good year for Sendai Domain. Narimura's wife died due to complications in childbirth of his eldest son. He shortly afterwards he received word of his father's death at the clan residence in Edo. On his way back to Sendai after the funeral, he fell ill near Shirakawa, and died shortly after returning home to Aoba Castle at the age of 23. 
As his heir Date Chikamune was still an infant and his second son (by a concubine), Date Narimune was still in his mother's womb, the domain took over a week to inform the authorities of Narimura's death, so that they could ensure that Narimune was posthumously recognised as Narimura's official son, and second in the line-of-succession.
