Inagi-Naganuma Station opened on 1 November 1927 with the Nambu Railway's extension from Noborito to Ōmaru in what is now Inagi, western Tokyo. The Nambu Railway was nationalised on 1 April 1944 and the station passed to JR East at privatisation on 1 April 1987. Freight handling ended on 1 March 1976 and parcel service on 14 March 1985. As part of a Nambu Line grade-separation project, the down tracks moved onto an elevated viaduct on 24 December 2011 and the up tracks followed on 23 December 2013, with platform 1 brought into service on 1 March 2015. The Midori-no-Madoguchi ticket office closed on 28 February 2021 and smart platform-edge doors entered service on platforms 1 and 4 on 19 February 2024.

A life-size monument of the Scopedog mecha from the anime Armored Trooper VOTOMS stands in the plaza outside the south exit, partly paid for by hometown mechanical designer Kunio Okawara.
