History
Nangō-Nana-Chōme Station opened on 21 March 1982 with the Sapporo Municipal Subway Tōzai Line extension from Shiroishi to Shin-Sapporo, having been provisionally called Nangō Station during planning. It is the only underground station in the network with a 2-platform/3-track layout, the centre track flanked by both platforms; the unusual configuration once featured on the station's commemorative stamp. As part of preparations for the Tōzai Line's full conversion to platform-edge doors and one-man operation, doors were installed on the centre track's number-4 platform in February 2008 as a pilot. Lifts entered service in July 2007.

Notes
Nangō-Nana-Chōme is the only Sapporo Municipal Subway station built with a 2-platform/3-track layout—the centre track is shared between the two platforms, an arrangement otherwise found in Tokyo on Toei Shinjuku Line stations like Iwamotochō and Ōjima.
