The Tokyo Bay coastal area is an industrial landfill from the south coast of Kisarazu Port to the direction of Kimitsu.

Chiba Prefecture Kisarazu has a humid subtropical climate (Köppen Cfa) characterized by warm summers and cool winters with light to no snowfall.

It was this site that received the remains of Admiral Isoroku Yamamoto after being transported back to Japan aboard Japanese battleship Musashi.

Kisarazu has a mayor-council form of government with a directly elected mayor and a unicameral city council of 24 members.

In terms of national politics, the city is part of Chiba 12th district of the lower house of the Diet of Japan.

Kisarazu has a mixed economy based on commercial fishing, agriculture, and heavy industry along its Tokyo Bay shoreline.

It serves as the commercial center for central Bōsō Peninsula, and is increasingly a bedroom community for neighboring Kimitsu and the Kawasaki – Yokohama metropolis across Tokyo Bay.

The opening of the Tokyo Bay Aqua-Line has also resulted in the creation of a number of factory outlet shopping malls, and the development of new towns, and land prices increased dramatically in the 1980s through 2000s.
