Tochigi is located in the very southern portion of Tochigi Prefecture, bordering on Ibaraki Prefecture and Gunma Prefecture to the southwest. The city is located in the northern part of the Kanto plain, with a mountain range extending in the northern part of the city. The Tomawa River runs through the city center, the Oshigawa River runs through the eastern part, and the Watarase River runs through the southern part. At the confluence of these three rivers is the Yanaka Reservoir, which is used for sailboating and windsurfing. It was designated a Ramsar Site in June 2012.

In the Edo period, Tochigi prospered from its location on the Uzumagawa River, which connected with the Tone River to Edo. Envoys using the Reiheishi Way sent from the Imperial Court going to Shrines and Temples of Nikkō stayed at the lodging area in the city. Most of the area was formerly tenryō territory controlled directly by the Tokugawa shogunate; however, the minor feudal domain of Fukiake Domain was located within the borders of modern city of Tochigi.

Following the Meiji Restoration and the creation of Tochigi Prefecture, Tochigi Town was the prefectural capital from 1871 until its relocation to Utsunomiya in 1884. On April 1, 1937, Tochigi was elevated to city status.

On September 30, 1954, Tochigi absorbed the villages of Ōmiya, Minagawa, Fukiage and Terao (all from Shimotsuga District). This was followed by the village of Kōō (from Shimotsuga District) on March 31, 1957. Tochigi hosted its first film festival, the Kuranomachikado, or, "Eizo Film Festival" from October 5, 2007, to October 8, 2007.

On March 29, 2010, Tochigi absorbed the towns of Fujioka, Ōhira and Tsuga (Shimotsuga District). This was followed by the town of Nishikata (from Kamitsuga District) on October 1, 2011, and the town of Iwafune (from Shimotsuga District) on April 5, 2014.

Tochigi has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 30 members. Tochigi contributes four members to the Tochigi Prefectural Assembly. In terms of national politics, the city is divided between the Tochigi 2nd district, Tochigi 4th district and Tochigi 5th district of the lower house of the Diet of Japan.
