Ekimae Line

The line opened on 16 February 1928, built by Tosa Denki (Tosa Electric) under the name "Enokuchi Line" (江ノ口線) and running from Harimayabashi to Kōchi-ekimae. The name "Ekimae Line" had long been used informally, but the section was not listed as an independent line in the official Tetsudō Yōran railway register until the 2006 (Heisei 18) edition; before that it was recorded as part of the Sanbashi Line.

As with the rest of the Kōchi tram network, the operating company changed hands repeatedly. On 12 July 1941 the line became part of Tosa Kōtsū following a merger and change of company name, and on 3 June 1948, after a merger with Nankai Tan'atsuki, it passed to the Tosa Electric Railway company. On 24 May 1951 the track near the Kōchi-ekimae stop was realigned, the curve being shifted from a left-hand to a right-hand bend.

For the rest of the twentieth century the short line saw only occasional works. On 31 March 1997 its overhead wiring was converted to centre-pole support, the work being carried out together with the Harimayabashi–Ume-no-tsuji section of the Sanbashi Line. The line's modern shape began to take form at the turn of the century, when attention turned to improving the connection with Kōchi Station and the through-running of trams onto the wider network.

The years around 2001 brought the line's most visible changes. On 27 March 2001 a new stop, Kōchi-bashi, opened between Hasuikemachi-dōri and Kōchi-ekimae, and on 1 April 2001 the Kōchi-ekimae terminus was moved into the rotary directly in front of Kōchi Station. From 2002 a demonstration trial of through services ran from Kōchi-ekimae toward Masugata and Kagamigawabashi on the Ino Line, and on 1 April 2005, after the intersection near Harimayabashi was rebuilt to add a right-turn track from the Ekimae Line onto the Ino Line, those through services entered regular operation.

From the 2006 edition of the Tetsudō Yōran, the Kōchi-ekimae–Harimayabashi section was formally separated from the Sanbashi Line and listed independently under the name Ekimae Line. The terminus moved once more after Kōchi Station itself was raised onto an elevated structure in 2008: on 14 February 2009 the Kōchi-ekimae stop was shifted about 30 metres north and brought into provisional use on one of its two tracks, and on 11 March 2009 the relocation work was completed and both tracks entered full service.

The line's most recent change of ownership came on 1 October 2014, when Tosa Electric Railway was brought together with Kōchi-ken Kōtsū and Tosaden Dream Service in a business integration, and the Ekimae Line — along with the rest of the former Tosa Electric Railway tram network — passed to the newly formed operator Tosaden Kōtsū. Today most Ekimae Line services run through onto the Sanbashi Line, roughly eight trams an hour, with a weekday-morning through service to the Ino line, carrying passengers the short distance between the centre of Kōchi and the station forecourt.
