is a station on the Toei Subway in Minato, Tokyo, Japan. The station is named after the Shiba Daimon or Great Gate of Shiba, located just west of the station on the road leading to the temple of Zōjō-ji.
Daimon is adjacent to Hamamatsuchō Station, which is served by JR East and the Tokyo Monorail. On the Toei lines, Daimon is called "Daimon Hamamatsucho" in certain automated announcements. The Oedo Line station, which occupies most of the space between the Asakusa Line and the JR lines, was initially planned to be called "Hamamatsucho" but ultimately adopted the name of the existing Asakusa Line station.
October 1, 1964: Opened as a station on Toei Subway Line No.1 (Asakusa Line).
