• Negishi Line: Negishi (Kanagawa) ⇄ Shin-Sugita

Isogo Station opened on 19 May 1964 as the terminus of the new Negishi Line, which then ran only from Sakuragicho. Freight handling started on 1 June 1964 with the Takashima Line through-connection. The Negishi Line was extended south to Yokodai on 17 March 1970, making Isogo an intermediate station. Freight ended on 1 November 1986, and the station passed to JR East at privatisation in April 1987. A west-side building was completed on 26 October 2001 and Suica use began on 18 November 2001. The Midori-no-madoguchi ticket office closed on 17 July 2020 and was replaced with an assisted reserved-seat ticket machine. Smart platform-edge doors began service on 13 June 2025.

Roughly a third of Keihin-Tōhoku/Negishi Line trains start or terminate at Isogo, and an 11-track stabling yard — the Isogo sub-depot of the Kamakura Rolling Stock Centre — spreads across the north-east side of the station.
