History
Tochōmae Station is a subway station on the Toei Ōedo Line in Shinjuku, Tokyo, designated E-28. Construction began on 28 August 1990 and the station opened on 19 December 1997, taking its name from the Tokyo Metropolitan Government Building immediately above. Built using cut-and-cover methods, the three-level underground station is 443 m long and required excavation of roughly 284,000 cubic metres. It has two island platforms serving four tracks on basement level 3. Tochōmae has the unusual distinction of being both a terminus and a through station on the same line: inbound trains pass through, complete a counter-clockwise loop around central Tokyo, and return to terminate here, with outbound services doing the reverse.

Notes
Because the Ōedo Line loops around central Tokyo and terminates back at Tochōmae, passengers may end up transferring "from the Ōedo Line to the Ōedo Line" at the same platform.
