The Ryugasaki Newtown sector has been inhabited since prehistoric times: the Pre-Doki (earthenware) period over 10,000 years ago. The straw-rope-pattern pottery of the Jomon period (around 8000 to 200 B.C.) and pottery of the Yayoi period (around 200 B.C. to 200 A.D.) have also been found. The Nagamine and Ohtsuka mound tombs of the later Kofun period have also been uncovered, attesting to the fact that powerful families lived here. During the much later Kamakura period, Lord Shimokawabe and his descendants started farming in this area. This powerful family renamed itself Ryuzaki and build the Ryugasaki Castle. Later the Toki family ruled. In the Yedo period, the land around Ryugasaki was considered an autonomous area of the Date (pronounced "Dah Teh") family in Sendai, with a guard post being built. It was during this period that the present town framework was built. The present Ryugasaki city was born in 1954, a union of seven towns.
