History

The area of present-day Hachiōji was part of ancient Musashi Province. It has been an important junction point and post town along the Kōshū Kaidō, the main road that connected the historical Edo (today's Tokyo) with western Japan. Hachiōji Castle was built during the Sengoku period in 1584 by Hōjō Ujiteru, but was destroyed in 1590 by Toyotomi Hideyoshi. During the Edo period, the area was tenryō controlled directly by the Tokugawa shogunate. In the post-Meiji Restoration cadastral reform of July 22, 1878, the area became part of Minamitama District in Kanagawa Prefecture. The town of Hachiōji was created on April 1, 1889, with the establishment of the modern municipalities system. Minaitama District was transferred to the administrative control of Tokyo Metropolis on April 1, 1893. Hachiōji gained city status on September 1, 1917.

During the 1964 Summer Olympics, the city was host to the cycling events. The Hachioji Velodrome was used for the events.^[6]

Hachiōji became a Core city on April 1, 2015 with increased local autonomy.

Government

Hachiōji has a mayor-council form of government with a directly elected mayor and a unicameral city council of 40 members, whose members are elected for a four-year term. Hachiōji contributes five members to the Tokyo Metropolitan Assembly. In terms of national politics, the city is divided between the Tokyo 21st district and Tokyo 24th district of the lower house of the Diet of Japan.

Economy

During the Meiji period, Hachiōji prospered as an important location for the production of silk and silk textiles. The industry faded away, however, in the 1960s. Today, Hachiōji mainly serves as a commuter town for people working in Tokyo, and as a location for many large colleges and universities.
