As with all of Kōchi Prefecture, the area of Tosa was part of ancient Tosa Province. Remains from the Jōmon period dated to 4000 years ago have been found within the city limits. During the Edo period, the area was part of the holdings of Tosa Domain ruled by the Yamauchi clan from their seat at Kōchi Castle. Following the Meiji restoration, the village of Takaoka (高岡村) was established within Takaoka District, Kōchi with the creation of the modern municipalities system on October 1, 1889. Takaoka was elevated to town status on March 1, 1899. Takaoka was elevated to city status on January 1, 1959, and renamed Tosa.
Tosa has a mayor-council form of government with a directly elected mayor and a unicameral city council of 15 members. Tosa contributes one member to the Kōchi Prefectural Assembly. In terms of national politics, the city is part of Kōchi 1st district of the lower house of the Diet of Japan.
Benefiting from the warm climate and abundant water, the area has long been a prosperous region for agriculture, with greenhouse horticulture in the plains and fruit tree cultivation in the surrounding mountains. In addition, the rich subsoil water of the Niyodo River has nurtured the paper industry, and in the Usa neighborhood, which faces the Pacific Ocean, coastal fishing and seafood processing have developed as key industries.
Tosa has nine public elementary schools and three public middle schools operated by the city government and two public high schools operated by the Kōchi Prefectural Department of Education. There is also one private high school. The Kochi Professional University of Rehabilitation is located in Tosa.
Tosa does not have any passenger railway service. The nearest train station is Ino Station on the JR Shikoku Dosan Line.
