Date is a city in Iburi Subprefecture, Hokkaido, Japan. Date was established around 1869 and became a city on April 1, 1972.
Remains of settlements from the Jōmon period have been found in the Date area. The Ainu, the native inhabitants of Hokkaido, also maintained a settlement at another location nearby until the beginning of the 20th century, when the Ainu were mostly assimilated into Japanese society.
The name of the area comes from the Date clan, who rose to power in the 12th century in Fukushima, on the mainland. Before the Edo period, their home castle was the Yanagawa castle in Date District, Fukushima. Later, it became the Sendai castle. The Date clan ruled the whole of Miyagi Prefecture as well as the southern part of Iwate Prefecture, and was one of the most influential daimyōs.
