History
Akabane-iwabuchi Station opened on 29 November 1991 as part of the Teito Rapid Transit Authority (TRTA, Eidan) Namboku Line in Kita, Tokyo. The station became the northern junction with the third-sector Saitama Rapid Railway Line when that line opened on 28 March 2001, and most Namboku trains today through-run to Urawa-Misono. Following the privatisation of Eidan in 2004, the facility was inherited by Tokyo Metro and is numbered N-19. From the 18 March 2023 timetable revision, through services were extended south via the new Tōkyū Shin-Yokohama Line and Sōtetsu Shin-Yokohama Line, with most southbound trains beyond Hiyoshi continuing to Shin-Yokohama and Ebina.

Notes
Although named after the Iwabuchi neighbourhood, the station sits roughly 400 metres from the much larger JR Akabane Station — close enough that the underground exit is the everyday transfer point between the Namboku Line and the Saikyō, Keihin-Tōhoku and Utsunomiya/Takasaki lines above.
