History
Nishi-Ōtaki Station opened on 1 December 1923 on the Iiyama Line in Iiyama, Nagano. Operated for decades by the JNR and then by JR East, it sits 39.7 kilometres from the line's origin at Toyono and serves a single ground-level side platform along a bi-directional track. With the privatisation of Japanese National Railways on 1 April 1987 the station joined JR East. A new station building was completed in 1997, and the small unstaffed stop continues to serve the riverside community along the Chikuma River and National Route 117.
