The story

Tosa Electric Railway was founded on 8 July 1903, and the tram line was opened on 2 May 1904. The company also operated a heavy railway line called Aki Line (安芸線) until its closure in 1974. The company was commonly known as Toden (土電) among locals, while people in other prefectures tend to call it Tosaden (土佐電), as the word Toden can be confusing with Tokyo Metropolitan Tramway, which was commonly called Toden (都電).

Tosa Electric Railway and Kōchiken Kōtsū introduced DESUCA, a smart card (IC card) ticket system, in January 2009.

In June 2014, the shareholders of Tosa Electric Railway and Kōchiken Kōtsū, both in the state of insolvency, approved the reconstruction plan, under which the companies' businesses be transferred to the newly established company funded by Kōchi Prefecture and other 12 municipalities. The name of the company was selected from 1,235 proposals from the public.
