The JR East portion of Higashi-Kawaguchi Station opened on 1 April 1973 with the inauguration of the Musashino Line, and was one of the original twelve stations to receive pilot automatic ticket gates. Operation transferred to JR East at the 1987 privatisation, and the Midori-no-Madoguchi window opened in November 1992. The Saitama Rapid Railway Line platforms, built underground, opened on 28 March 2001, turning the stop into a JR–third-sector interchange. Suica became usable on 18 November 2001 and PASMO on 18 March 2007. Barrier-free upgrades and a new south-side station building were completed between 2010 and 2011. The staffed Midori window was withdrawn on 22 July 2022, and the JR portion became a sub-station under Minami-Koshigaya the following month.

A replica cutter head from the tunnel-boring machine used to dig the Saitama Rapid Railway Line is displayed in front of the station.
