Early historyEdit

The area of modern Kisarazu has been inhabited since the Japanese Paleolithic period, and numerous remains from the Jōmon, Yayoi and Kofun periods have been found within the city limits. 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 PrefectureEdit

Kisarazu was part of the complex reconfiguration of administrative areas at the start of the Meiji period. In 1871, as part of the abolition of the han system, the Sakurai Domain, located partly in Kisarazu, was abolished and "Sakurai Prefecture" was established.

In November of the same year, the prefecture was combined with the former Awa Province and Kazusa Province to form "Kisarazu Prefecture". The prefectural seat was established in the present-day Kaifusa district of Kisarazu. Kisarazu Prefecture was established two years later in 1873. It was combined with Inba Prefecture to form present-day Chiba Prefecture.

World War II and Post-War PeriodEdit

Kisarazu was developed as a center for military activity as part of the militarization of Japan in the 1930s. In 1935-1936 the Imperial Japanese Navy, established the Kisarazu Air Field for the Kisarazu Air Group on landfill in the northern part of Kisarazu to protect Tokyo from attack. The base served as an arsenal for the IJN, and employed up to 17,000 workers during the war. It was this site that received the remains of Admiral Isoroku Yamamoto after being transported back to Japan aboard Musashi. 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". In 1956, the base was officially transferred to the control of the Japan Air Self-Defense Force (JASDF).
