Minami-Omachi

Departure data for this station is not available on this site.

Minami-Ōmachi Station opened on 1 February 1934 as Shōwa Station, a Shinano Railway stop built to serve the Showa Denko Omachi plant on the east side of the tracks (the plant name supplying the station name). When the Shinano Railway was nationalised on 1 June 1937 the station was renamed Minami-Ōmachi. Parcel handling ended on 25 March 1983 and the station was destaffed and put under simple-commission management. It passed to JR East with the 1987 JNR privatisation, and on 14 March 2026 the surrounding stretch of the Ōito Line was incorporated into the Tokyo suburban zone, although Suica is not accepted at the station itself.

The current bridge over the Takase River near the station was relocated here from the Kagoshima Main Line's crossing of the Onga River, where it had been erected in the Meiji era.
