History
The area around Kamagaya has been inhabited since prehistory, and archaeologists have found Jōmon periodshell middens in the area.[5] During the Kamakura period, the area was controlled by the Sōma clan. Kamagaya flourished in the Edo period 1603–1868 when the area was largely tenryō territory within Shimōsa Province controlled directly by the Tokugawa shogunate. One part of present-day Kamagaya was part of the Kogane Ranch, which raised war horses for the army of the Tokugawa shogunate. In the Edo period Kamagaya was also a thriving shukuba post on the Kioroshi Road, which connected present-day Inzai on the Tone River to Edogawa-ku in Tokyo. The road was utilized to bring fresh fish and other marine products from the Tone River region to the capital Edo.[6] After the Meiji Restoration, it became part of Chiba Prefecture. Kamagaya Village was one of several villages created on April 1, 1889 under Inba District with the establishment of the modern municipalities system. In 1945, the Imperial Japanese Army appropriated the former Musashino Country Club, turning the golf course into an air field. The base was turned over to the United States Air Force after World War II, becoming Shiroi Air Base, and was transferred to the Japan Maritime Self-Defense Force in 1959, becoming JMSDF Shimofusa Air Base. Kamagaya became a town on August 1, 1968, and was elevated to city status on September 1, 1971.
