History

The entire line opened on 12 June 1910, 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.

From the start of the 26 March 2016 timetable revision, the line was branded the Uno Port Line.
