Inadazutsumi opened on 1 November 1927 as a halt on the privately built Nambu Railway between Noborito and Ōmaru, becoming a full station with goods handling the following year. Freight ceased in 1955 and parcel traffic in 1974. The Nambu Railway was nationalised on 1 April 1944, and the station passed to JR East at privatisation on 1 April 1987. A complete rebuild added a south exit, an overhead concourse and a free pedestrian passage: a temporary building entered use on 6 June 2021, the overhead concourse and southern side on 6 August 2023, and the northern side on 2 June 2024. Smart platform doors followed on 13 September 2024.

Between August 2023 and March 2025 trains departed to a recording of "Oka o Koete" — a 1931 song said to be inspired by the Tama riverbed scenery around Inadazutsumi.
