History
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 bypass the area to the south with no station, but the Japan Housing Corporation, which was developing the surrounding new town, secured a station and a northward route shift in exchange for accepting the change; construction of the Kōnandai Tunnel through the station area was a concession to keep the new residential blocks unbroken. 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.

Notes
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.
