Hyōgo Prefecture Takarazuka has a humid subtropical climate (Köppen Cfa) characterized by warm summers and cool winters with light snowfall.

From the Heian period, numerous landed estates shōen controlled by the Fujiwara family were developed in the area.

The village of Kohama (小浜村) was established on April 1, 1889 within Kawabe District, Hyōgo, with the creation of the modern municipalities system.

At one time, the idea was raised of merging Takarazuka with Itami, Kawanishi, and Inagawa, but it is currently on hold.

Takarazuka has a mayor-council form of government with a directly elected mayor and a unicameral city council of 26 members.

In terms of national politics, the city is divided between the Hyōgo 6th districts of the lower house of the Diet of Japan.

It is increasingly becoming a bedroom community for Osaka and Kobe, with quiet, upscale residential neighborhoods like Nigawa, Obayashi, Sakasegawa, and Hibarigaoka.
