Kawaguchi Station opened on 10 September 1910 as Kawaguchi-machi Station (川口町駅) on the Tōhoku Main Line. When Kawaguchi was incorporated as a city in 1934, the station was renamed Kawaguchi on 15 February 1934, after a same-name station further north was renamed Iwate-Kawaguchi two weeks earlier. Freight handling ceased on 1 November 1986, and the station passed to JR East at privatisation on 1 April 1987. Automatic ticket gates entered service on 30 May 1992, and Suica IC fares became valid on 18 November 2001. Platform doors opened on 15 June 2019. In 2024 JR East and Kawaguchi City agreed on a plan to add Ueno-Tokyo Line platforms; the funding agreement was signed on 24 April 2025.

Kawaguchi Station could take the plain name Kawaguchi only once the other Kawaguchi Station, further north on the Tōhoku Main Line, was renamed Iwate-Kawaguchi — a change made fourteen days earlier. This station, which had opened as Kawaguchi-machi, was renamed Kawaguchi on 15 February 1934 on Kawaguchi-machi's elevation to city status.
