History

It effectively became an intermediate station on 14 October 1969 when the Seibu Chichibu Line opened, making it the junction between the Seibu Ikebukuro Line and the Seibu Chichibu Line. Freight handling ended on 31 March 1978, the present station building entered service on 25 April 1997, and station numbering ("SI31") was introduced in 2012. The station has one island platform serving two tracks. It carries the dual role of Ikebukuro Line terminus and Chichibu Line origin.
