History
Yonohommachi Station opened on 30 September 1985 as one of the original stops on the new Saikyō Line, built alongside the Tōhoku Shinkansen viaduct between Ōsaki and Ōmiya. Operation transferred to JR East at the 1987 privatisation. A station building branded "Alcade Yonohommachi" opened on 8 March 1989 and was rebranded "Beans Yonohommachi" on 15 November 1991. Automatic ticket gates were installed on 31 August 1993, and Suica was introduced on 18 November 2001. The Midori-no-Madoguchi staffed ticket office closed on 10 April 2015, and the on-platform kiosk shut on 25 August 2023. The station was assigned station code JA 24, with "flesh" as its identifying colour, when Saikyō-Line numbering was rolled out.

Notes
Saikyō Line trains run beside the Tōhoku Shinkansen viaduct directly adjacent to the station's west side, an inheritance from the Shinkansen construction agreement that brought the parallel commuter line.
