The area of modern Takasago is part of ancient Harima Province. It has been settled since prehistoric times, and shell middens from the Jōmon period have been found along the coast. The area has been used as a quarry since at least the Kofun period and sarcophagi made from Takasago tuff have been found throughout the Kinai area. The place name "Takasago" is found in early Heian period documents, and it was known as a fishing port and for salt production. It was transformed into a castle town from the Muromachi period, and was a base of operations for Hashiba Hideyoshi's conquest of western Japan in the Sengoku period. In the Edo Period, its role was eclipsed by neighboring Himeji; however, it continued to prosper as a distribution center for goods based on shipping on the Kakogawa River, and as a key port for Himeji Domain. Takasago served as the inspiration for naming sumo wrestler Takasago Uragorō, who wrestled under the patronage of the Himeji. By extension, the town gave its name to Takasago stable.

The town of Takasago was created with the establishment of the modern municipalities system on April 1, 1889. On July 1, 1954 Takasago merged with the village of Arai and the town of Sone and village of Iho from Innami District to form the city of Takasago.

Takasago has a mayor-council form of government with a directly elected mayor and a unicameral city council of 19 members. Takasago contributes one member to the Hyogo Prefectural Assembly. In terms of national politics, the city is part of Hyōgo10th district of the lower house of the Diet of Japan.

Takasago is located within the Harima Seaside Industrial Area and is a center for heavy industry, including steel mills, refineries and chemical processing. Many factories for major companies dot its skyline in the south, such as Mitsubishi Hitachi Power Systems, the Kobe Steel Takasago Manufacturing Complex, Mitsubishi Paper Mills, Takuma Power Plant, and Kikkoman Soy Sauce. In recent years, problems with industrial pollution, especially bottom sediment pollution caused by PCBs has become a political issue.
