Iwanami Station traces its origins to the Iwanami Signal Station, opened on 1 May 1911 on what was then the Tōkaidō Main Line between Gotenba and Sano (today's Susono). Reclassified as a signal post in April 1922, it was upgraded to a full passenger station on 8 December 1944, by which time the line had been relabelled the Gotenba Line. The line through Iwanami was singled in July 1943 and electrified on 1 July 1968, when the old switchback layout was abolished. With JNR privatisation on 1 April 1987 the station passed to JR Central. A new ground-level station building, an additional up platform and a multi-purpose toilet entered service on 26 May 2019.

From 1969 to 1982 the station handled freight over a Toyota Motor private siding that took finished cars out of the Higashi-Fuji plant; the siding left the Gotenba Line about one kilometre north of the station. On the Numazu side of the station an embankment still survives, overgrown, as a trace of the pull-out track from the former switchback.
