[4] The station, which is unstaffed, consists of a side platform serving a single track.

It was among a string of three intermediate stations which were set up when the then Yosan Mainline was extended westwards from Yawatahama to link up with track of the then Uwajima Line at Unomachi.

This was the final phase of the extension of the Yosan Mainline which connected Takamatsu with Uwajima.

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