Nippon Tetsudō
Nonai Station was opened on 16 July 1893 as a station on the Nippon Railway in the former village of Nonai. It became a station on the Tōhoku Main Line of the Japanese Government Railways (JGR), the pre-war predecessor to the Japanese National Railways (JNR), after the nationalization of the Nippon Railway on 1 November 1906. With the privatization of JNR on 1 April 1987, the station came under the operational control of East Japan Railway Company (JR East).
