Tameike-sanno Station
G06 N06 · Ginza Line and Namboku Line · Chiyoda
Tameike-sanno Station (溜池山王)
Both sets of platforms here opened on the same day, 30 September 1997, and the station exists because of the interchange rather than the other way round: it was inserted into the Ginza Line as an infill station so that the new Namboku Line could meet it, and N06 opened as the southern end of that line. G06 and N06 share two island platforms and four tracks.
The name was fought over. Minato Ward wanted Tameike, after the Tameike stop on the Toden tram line that ran above ground along Sotobori-dori from 1905 until 1967; Chiyoda Ward pushed for Sannoshita, after another stop on the same line. The station straddles the boundary, with the Namboku platform in Chiyoda and the Ginza platform in Minato, and the dispute was settled by taking a piece of each name. Underground passages join it to Kokkai-gijidomae on the Marunouchi and Chiyoda lines, and the change can be made without passing a ticket gate, though it is a long walk. In 2025 Tameike-sanno was used by 131,557 people on an average day.

Frequently asked questions
Because two wards wanted different ones. Minato Ward argued for Tameike and Chiyoda Ward for Sannoshita, both after stops on the tram line that once ran overhead, and the station sits on the border between them. Rather than choose, the operator combined the two into Tameike-sanno.
It has its own name, its own numbers and its own lines, the Marunouchi and the Chiyoda. In practice the two are joined by underground passages and you can walk between them without going through a ticket gate, so the operators record the change as a single transfer. Allow for an appreciable walk.
