Kōshū Kaidō
The area of present-day Chōfu has been inhabited since Japanese Paleolithic times, and numerous remains from the Jōmon, Yayoi and Kofun periods have been discovered. During the Nara period, it became part of ancient Musashi Province. During the Sengoku period, the area was frequently contested between the Later Hōjō clan and Uesugi clan. During the Edo period, the area prospered as a post station on the Kōshū Kaidō and as a center for sericulture. The origin of the city name "Chōfu" comes from the fact that it was allowed to pay taxes cloth instead of rice.
