  ## History
  
  The station was opened on 28 June 1903 by the private Hokkaido Railway as an intermediate station during the phase of expansion when the track was extended north from Hongō (today Shin-Hakodate-Hokuto) to Mori. After the Hokkaido Railway was nationalized on 1 July 1907, Japanese Government Railways (JGR) took over control of the station. On 12 October 1909 the station became part of the Hakodate Main Line. On 1 April 1987, with the privatization of Japanese National Railways (JNR), the successor of JGR, control of the station passed to JR Hokkaido.
