Tadotsu Station opened on 23 May 1889 as a station on the private Sanuki Railway between Marugame and Kotohira, in what is now Tadotsu, Kagawa Prefecture. The original site was a switchback close to the port to connect with ferry services from the Hanshin region. Sanuki Railway was absorbed by the Sanyō Railway on 1 December 1904, and the network was nationalised on 1 December 1906. On 20 December 1913 the station was relocated to its present site to eliminate the switchback, with the old grounds reused as the Hama-Tadotsu freight depot. Following JNR's privatisation on 1 April 1987, control passed jointly to JR Shikoku and JR Freight; all limited-express trains have stopped here since the March 2012 timetable revision.

The premises include two Registered Tangible Cultural Properties — a turntable and a water tower — though the water tower was scheduled for demolition in late 2024 due to seismic and age concerns despite its protected status.
