is a subway station in Tokyo, Japan, operated by the Tokyo subway operator Tokyo Metro. It is located in the ward of Chiyoda (Namboku Line platform) and Minato (Ginza Line platform).
Tameike-sannō Station is served by the following two Tokyo Metro subway lines.
The station is also connected by underground passageways to Kokkai-gijidō-mae Station, which is served by the Tokyo Metro Marunouchi Line (with this transfer being an appreciable walking time) and Tokyo Metro Chiyoda Line, and it is possible to transfer between the two stations without crossing through the ticket gates.
The station has two island platforms serving four tracks.
The station opened on September 30, 1997, as the southern terminus of the Namboku Line. The Ginza Line platforms opened at the same time.
It is named after the nearby Tameike Crossing (which is itself named for a reservoir [''tameike''] which once covered the area) and the nearby Sanno Shrine (commonly known as the Hie Shrine). Both "Tameike" and "Sanno" are names of bus stops in the area. The station was originally to be named "Tameike Station" after the closer Tameike stop, but the Sanno name was added in order to satisfy Chiyoda Ward (as Tameike is associated with the Akasaka district of Minato Ward).
The station facilities were inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.[1]
In fiscal 2019, this station and combined[2] had an average of 150,922 passengers daily.
