History
Ichinowari Station opened on 1 October 1926 on the Tōbu Isesaki Line (now branded as the Tōbu Skytree Line) in what is now Ichinowari 1-chōme, Kasukabe, Saitama Prefecture. Departure melodies were introduced on 8 December 2011, and on 17 March 2012 the Tōbu numbering scheme assigned the station code TS 26. The schedule revision of 16 March 2013 abolished daytime semi-express services, leaving daytime service largely as Tokyo Metro Hibiya Line through trains, with Asakusa-bound trains running only in the morning and evening.

Notes
When the station opened in 1926, the local district was renamed from its old village name Ichinowari-mura (市野割村) to the current "Ichinowari" (一ノ割) — the station's opening directly triggered the place-name change.
