• Negishi Line: Yokodai ⇄ Hongodai

Kōnandai Station opened on 9 April 1973 with the extension of the JNR Negishi Line from Yōkōdai to Ōfuna. The route was originally planned to pass south of the site with no station here, but when the alignment had to be shifted northward the Japan Housing Corporation, which was developing the surrounding area as a housing district, accepted the change in return for a station being built; the Kōnandai Tunnel was driven through the station area so that the railway would not cut movement within the new housing district. The station passed to JR East at the 1 April 1987 privatisation of JNR. Automated turnstiles arrived on 8 March 1994, Suica on 18 November 2001, and the Midori no Madoguchi ticket office closed on 25 August 2022.

From roughly 1990 to 1998, in keeping with the slogan 'Kōnandai, a town of singing birds', recorded bird calls — a Japanese cuckoo for one track, a common cuckoo for the other — announced approaching trains at Kōnandai.
