• Negishi Line: Shin-Sugita ⇄ Konandai

Yōkōdai Station opened on 17 March 1970 as a terminus of the JNR Negishi Line, extended from Isogo. The surrounding land had been a small farming hamlet called Yabeno until rapid 1970s housing development; residents began moving in three months after the station opened. The Negishi Line was extended to Ōfuna on 9 April 1973, making Yōkōdai a through station. JR East took over on 1 April 1987 at JNR privatisation. Automated turnstiles followed in February 1994 and Suica IC card service in November 2001. For a period after opening only track 1 of the present two was laid, the space for the second being left unbuilt. Smart platform doors entered service on 5 July 2025.

The name Yōkōdai is said to derive from the morning sun rising over Tokyo Bay as seen from the area; it replaced the older place name Yabeno, which survives nearby only in the Yabeno Tunnel and the Yabeno Bridge overpass.
