History
Uonuma-Nakajō Station opened on 15 November 1927 on what is now the Iiyama Line, 78.4 km from the line's terminus at Toyono Station. The station joined the JR East network with the privatisation of Japanese National Railways on 1 April 1987, and has long operated as an unstaffed halt with a single side platform serving one bi-directional track. It serves the rural southern part of Tōkamachi in Niigata Prefecture, near National Route 117 and the local Nakajō middle school, with passenger ridership reflecting the line's role as a connector through the heavy-snow zone of the upper Shinano valley.
