[4] The station, which is unstaffed, consists of an island platform serving two tracks.

Subsequently, the track of the then Yosan Mainline was extended westwards from Yawatahama and linked up with the Uwajima Line at Unomachi on 20 June 1945.

The Uwajima Line and its stations, including Tachima, then became part of the Yosan Mainline from that date.

With the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku.
