History
Kotohira Station opened on 23 May 1889 as a station on the Sanuki Railway. The Sanuki Railway was acquired by Sanyo Railway in 1904, and was nationalized in 1906. In November 1922, the station was relocated to its present site, with the former station becoming Kotohira Station of the Kotohira Sangu Electric Railway. The current station building was completed in 1936. At that time the station was operated by Japanese Government Railways, later becoming Japanese National Railways. With the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku.
