From its border with Himi down to the southwest area of the city, a range of mountains stretch for roughly 150 m to 300 m with a particularly high stretch of mountains centering on Mt. Futagami near Himi. Shogawa River and the Oyabegawa River run through Takaoka, and tributaries weave their way through the city center. Including small rivers, a total of 10 rivers flow through the city. The Amaharashi coast lies to the north of the region. Just off the coast lies the uninhabited offshore rock of Otokoiwa. Another uninhabited rock, Onnaiwa, lies nearby, and the view of this island against the backdrop of the Tateyama range of peaks is famous and features in promotional media for the region. A section of the Imizu plains runs from the central district of the city to the eastern district, and the Tonami plains which stretch from the west to the south are dotted with dispersed settlements in certain areas.

The area of present-day Takaoka was part of ancient Etchū Province, and the provincial capital was located in what are now the outskirts of the modern city. Ōtomo no Yakamochi took office as a government official in this area in the 8th century. During his five-year stay, he wrote many waka poems. This is the reason for Takaoka being nicknamed Manyō City.

Originally, the Takaoka region was called Sekino, but when Maeda Toshinaga of Kaga Domain took control of the city in 1609, he named it after a verse from the religious poem Shihen which includes the word Takaoka. In addition to this, the fact that Takaoka Castle was built on a slightly elevated shoreline is thought to be another possible origin for the name Takaoka, since Taka means "high" and Oka means "hill or elevated land".

Despite the loss of its castle due to orders from the Tokugawa shogunate in 1615, the Maeda clan pursued policies regulating the relocation of Takaoka citizens and promoting the development of Takaoka as an industrial city. This resulted in the start of Takaoka's role as a city of commerce and industry. Takaoka copperware and lacquerware also took off at this time.

Following the Meiji restoration, with the establishment of the municipalities system on April 1, 1889, Takaoka was registered as one of Japan's first 30 cities. The area around Fushiki Port was declared an open port for foreign trade by Imperial decree in July 1899.

On November 1, 2005, the town of Fukuoka (from Nishitonami District) was merged into Takaoka. Nishitonami District was dissolved as a result of this merger.

Takaoka has a mayor-council form of government with a directly elected mayor, and a unicameral city legislature of 27 members. The city contributes seven members to the Toyama Prefectural Assembly. In terms of national politics, the city is part of the Toyama Third Electoral District for the lower house of the Diet of Japan.
