Nishijo

No publicly available departure data for this station.

Nishijō Station opened on 1 November 1900 as the temporary terminus of the government-operated Shinonoi Line, becoming an intermediate stop the following year when the line was extended to Matsumoto. Freight handling ended in December 1971, and the station became an unstaffed simple-contract station in March 1985. It passed to JR East with the privatisation of JNR on 1 April 1987. In September 1988 the alignment between Akashina and Nishijō was rerouted, eliminating the former Shiozawa signal stop. The line received station-numbering codes in February 2025 (with Nishijō becoming SN09), and Suica IC card service began on 15 March 2025.

Because Japan has another Saijō Station in Hiroshima Prefecture, tickets issued from this Nagano station carry the prefix "（篠）" ("Shinonoi") to distinguish the two homophones.
