Hongō-sanchōme Station opened on 20 January 1954 as a Teito Rapid Transit Authority Marunouchi Line stop. The original side platforms were 80 m long, sized for four-car trains, with 40 m of tunnel reserved at the Ikebukuro end for future expansion; that extension was carried out in 1960 to allow six-car operation. The April 1965 residential-address reform shifted the surrounding district from Hongō 3-chōme to Hongō 2-chōme without moving the station. Toei opened a separate Ōedo Line platform here on 12 December 2000; the two stations are not connected underground because building a through-passage would have required acquiring private land. A two-year rebuild of the Marunouchi entrance finished on 22 November 2002, and platform doors entered service in 2006.

The Marunouchi and Ōedo line stations at Hongō-sanchōme are not linked underground — a connecting passage would have encroached on private land and pushed up costs, and the walk between them at street level is short — so transferring between the two lines means leaving the paid area and going up to the surface. Installing a connecting passage was considered in 2011, but none has been built.
