• Toei Mita Line: Motohasunuma Sta. ⇄ Itabashi-kuyakushomae

Itabashi-honchō Station opened on 27 December 1968 as part of the inaugural Toei Subway Line 6, in Yamatochō, Itabashi, Tokyo. The working name during planning had been Yamatochō, taken from the locality, but it was rejected because Line 6 was at the time slated for through-running with the Tōbu Tōjō Line and the planned interchange would have been at another Yamato-machi station — present-day Wakō-shi — risking confusion between two similarly named stops. Line 6 was redesignated as the Mita Line on 1 July 1978 and the station accepted PASMO IC cards from 18 March 2007. The underground station has two side platforms serving two tracks, with escalator access from the A3 exit and lifts linking the A1 and A3 exits with the unpaid concourse.

The working name during planning, Yamatochō, was dropped because the abandoned through-running plan with the Tobu Tojo Line would have shared its connection point with another Yamato-machi station — now Wako-shi Station.
