On October 14, Tokyo Metro and the Urban Renaissance Agency officially announced plans for a new subway stop along the Hibiya Line between Kasumigaseki and Kamiyacho Stations. The station will be located in the Toranomon district and will be just to the west of the recently completed Toranomon Hills.
Construction is scheduled to begin in 2015 with the new station expected to be open by the 2020 Tokyo Olympics, and an underground passageway to neighbouring buildings, including Toranomon Hills, ready by 2022.
The Toranomon area has been undergoing major redevelopment with new hotels, offices and residences. There are plans for a bus terminal to be located nearby the new station which could possibly serve as a transport link between the Olympic facilities in the bayside islands and central Tokyo.
This will be the newest station to be added to an existing subway line by Tokyo Metro since Tameike-Sanno Station was opened in 1997.
