The city is administered by an elected mayor who serves as the head of the executive branch, responsible for the day-to-day management of city services, the preparation of the annual budget, and the enforcement of municipal ordinances. The legislative authority rests with the Kisarazu City Council, a unicameral body composed of elected representatives who deliberate on local laws, approve the budget proposed by the mayor, and oversee administrative performance. The council members are elected by universal suffrage from single-member districts and at-large seats, serving four-year terms.

Kisarazu functions as a significant economic hub within Chiba Prefecture, leveraging its strategic location on the eastern shore of Tokyo Bay. The city's economy is characterized by a diverse mix of industrial, agricultural, and commercial activities, supported by its status as a major transportation node connecting the Kanto Plain to the broader Japanese archipelago.

Industrial and Commercial Sectors

The industrial landscape of Kisarazu is heavily influenced by its proximity to the capital region. Manufacturing and logistics form the backbone of the local industrial output, with numerous facilities utilizing the city's extensive waterfront for import and export operations. The presence of the Tokyo Bay Aqua-Line has significantly enhanced the city's commercial viability.

The region is known for its fertile land, which supports the cultivation of a variety of crops. While specific crop yields and agricultural revenue figures are not detailed in the immediate demographic data, the sector contributes to the local food supply and maintains the rural character of parts of the city.
