The area also is prominent in the Yamatotakeru mythology. Under the Ritsuryō system of the Nara period, the area became part of Kazusa Province. The area was contested between the Later Hōjō clan, Takeda clan and Satomi clan during the Sengoku period. During the Edo period under the Tokugawa shogunate, part of the area was under the control of the feudal domain of Jōzai, with large portions as tenryō territory controlled directly by the Shogunate and administered by numerous hatamoto.

Meiji Restoration and Kisarazu Prefecture Kisarazu was part of the complex reconfiguration of administrative areas at the start of the Meiji period.

The Nakajima Kikka, Japan's first jet-powered aircraft, was tested at the base in 1945. The base was used by the United States Air Force from 1945 as "Kisarazu Air Base".
