History
Naganuma Station opened on 24 March 1925 as a station of the Tamanan Electric Railway in what is now Naganuma-machi, Hachiōji, Tokyo. The operator was merged into Keio Electric Tramway (the predecessor of today's Keio Corporation) on 1 December 1926. It was absorbed into the wartime Tokyu (Dai-Tokyu) network on 31 May 1944 under the wartime land-transport reorganisation, and on 1 June 1948 Keio Teito Electric Railway separated from Tokyu and the station became theirs. Elevation work tied to construction of the Hachiōji Bypass of National Route 16 began in October 1983; the down-line elevation finished on 30 September 1989, and the up-line elevation and new station building were completed on 27 October 1990. It is station KO32 on the Keio Line.

Notes
The station name comes from the area at the confluence of the Asakawa and Yudonogawa Rivers near the present site, which once formed a long, broad marshland — "naganuma" (literally "long marsh") — giving its name first to the locality and then to the station.
