11 December 2017: Sōtetsu finalised the station name as Hazawa Yokohama-Kokudai Station.[2] However, as of that time the route name was still provisional. The station's name comes from its locale, Hazawa (羽沢), and also its neighbouring university, the Yokohama National University, or in Japanese, Yokohama Kokudai (横浜国大).
The station consists of two underground side platforms. At the east side of the station, the tracks for the JR Link Line and the Tōkyū Link Line diverge, with the JR Link Line converging with the Tōkaidō Freight Line after leaving the junction.[4]
