History
Higashi-Iwatsuki Station opened on 1 December 1969 as an infill stop between Iwatsuki and Toyoharu on the Tōbu Noda Line. The single-track Iwatsuki–Higashi-Iwatsuki segment was doubled on 25 November 1999, after which roughly half of the Ōmiya–Iwatsuki short-distance trains were extended to terminate here. A further doubling extended through Kasukabe on 19 October 2004, eliminating Higashi-Iwatsuki's role as a terminus. A new overhead station building broke ground in December 2004 and entered service on 1 November 2006, with the south exit completing later that day. Iwatsuki's merger into Saitama City on 1 April 2005 changed the station's address, and station numbering (TD 07) was added on 17 March 2012.
