History
Roppongi-itchōme Station opened on 26 September 2000 with the extension of the Teito Rapid Transit Authority's Namboku Line, having been planned under the working name Higashi-Roppongi. Tokyo Metro took over the station on 1 April 2004 following the agency's privatisation, and PASMO use began on 18 March 2007. The departure melody was changed on 11 March 2015 to dedicated tracks composed by Naoya Fukushima — "Sazanami" for track 1 and "Hidamari" for track 2. A new west exit opened in 2017 to serve the Sumitomo Fudosan Roppongi Grand Tower, and a south exit followed in 2024 alongside the Azabudai Hills development. The underground station has one island platform serving two tracks at the fourth basement level, with full-screen platform-edge doors.

Notes
Because the station sits close to the foundations of the Tokyo Metropolitan Expressway viaduct and four existing high-rise buildings, builders pioneered Tokyo's first "crosswise underground continuous wall" and "underwater excavation" subway-construction methods, partitioning the site into a 27-cell grid.
