Line info
The Fukutoshin Line is the deepest metro line in Tokyo, with an average depth of 27 meters.[3] At Shinjuku-sanchōme Station, the line passes under the Marunouchi and above the Shinjuku lines at a depth of 15 meters, with a gap of only 11 centimeters to the Shinjuku Line tunnel.[3] The deepest section is at the immediately adjacent Higashi-Shinjuku Station, where the line goes down to 35 meters, partly due to an underground space reservation for a possible future extension of the Jōetsu Shinkansen to Shinjuku

It is the second Tokyo Metro line to feature express services, after the Tōzai Line; however, unlike the Tozai Line (where rapid services are only offered on the Tōyōchō – Nishi-Funabashi section), the Fukutoshin Line offers express services throughout the line, a first for Tokyo Metro. Express trains pass local trains at Higashi-Shinjuku, where additional tracks are installed for this purpose. Local trains stop at all stations.

When first opened, the line operated through services to Kawagoeshi Station on the Tobu Tojo Line and Hannō Station on the Seibu Ikebukuro Line. From 16 March 2013, the Tōkyū Tōyoko Line moved to share the line's Shibuya terminus, and since then through services have operated onto the Minatomirai Line via the Tōyoko Line, terminating at Motomachi-Chūkagai Station in Yokohama.[4] This is a rare instance of a Tokyo Metro train operating on four companies' tracks.[5]

Between Kotake-Mukaihara Station and Shibuya Station the Fukutoshin Line operates as a one-man operation subway line where chest-high platform edge doors are installed on the station platforms to aid the drivers.[6]
