The entire line opened on 12 June 1910,[1] and until the opening of the Seto Ohashi Bridge in 1988, was the main railway connection to Shikoku (via the Takamatsu ferry). With the privatization of JNR on 1 April 1987, the line came under the control of JR West.[1]

From the start of the 26 March 2016 timetable revision, the line was branded the Uno Port Line (宇野みなと線, Uno-minato-sen).[2]
