Kōshū is located near the center of ancient Kai Province and contains many ruins from the Jōmon period and burial mounds from the Kofun period. During the Heian period, the area was developed in shōen under control of the Minamoto clan, which devolved into feudal holdings by the Nikaido clan and later the Takeda clan from the Kamakura through Sengoku periods. During the Edo period, all of Kai Province was tenryō territory under direct control of the Tokugawa shogunate. Following the Meiji restoration, the area was organized into villages within Yamanashi District of Yamanashi Prefecture, which was later divided into Higashiyamanashi District and Nishiyamanashi District Many of these villages were consolidated into the city of Enzan, the town of Katsunuma, and the village of Yamato by April 1, 1955. The modern city of Kōshū was established on November 1, 2005, from the merger of these three municipalities.
