Κότσι Γιουνάιτεντ

On February 1, 2016, two established Shikoku League clubs; Igosso Kōchi FC (アイゴッソ高知FC) and Kōchi U Torastar FC (高知UトラスターFC) merged to form one club, whose aim was to be the first team from Kōchi Prefecture to play in the J. League. After officially changing the management company's name to Kōchi United Sports Club Ltd., Kochi United SC took Igosso Kōchi FC's place in the Shikoku League. For the many players at Kōchi U Torastar FC unable to join Kochi United SC, and wanting to continue playing as amateurs in the Shikoku League, Kochi Sports Club Ltd. and Kochi University established KUFC Nangoku on March 1, 2016, and this new club took Kōchi U Torastar FC's place in the Shikoku League. The club badge depicts the ceremonial Keshō-mawashi (化粧廻し) of a Tosa Fighting Dog on the outside, with the dark red colors of Igosso Kochi FC and the green of Kōchi U Torastar inside it and an image of a leaping bonito or skipjack tuna drawn in the center (a popular fish in Kochi prefecture). The club's home shirt also reflects the colors of the amalgamated teams from which Kochi United SC was formed.

They played in the Shikoku Soccer League, one of the Japanese Regional Leagues from 2016–2019, winning it three times in a row from 2017–19. In 2019 they finished 2nd in the Japanese Regional Football League Competition, earning promotion to the Japan Football League from the 2020 season. In November 2021 they applied for J.League 100 Year Plan club status with the aim of becoming a fully professional club in the future. In February 2022 their application was approved.
