Tochōmae Station (都庁前駅, Tochōmae-eki, Metropolitan Government Station) is a subway station on the Toei Ōedo Line in Shinjuku, Tokyo, Japan, operated by the Tokyo subway operator Toei Subway.
Unusually, the station is both a terminus and a through station on the same line. Inbound trains pass through the station, travel south to complete a counterclockwise loop around central Tokyo, and terminate at Tochōmae. Outbound trains do the opposite, departing northbound from Tochōmae, traveling clockwise and eventually passing through the station again on the way out. Consequently, passengers may need to transfer from the Ōedo line to the Ōedo line at this station.
