History

Exit 13 during the TRTA era

The station was opened on September 30, 1997, as the southern terminus of the Namboku Line by the Teito Rapid Transit Authority (TRTA). The Ginza Line platforms opened at the same time.

It was built as an Infill station to allow interchange between the Ginza and Namboku Lines.

The station was initially given the provisional name "Tameike Station." However, because it was built on the border between Minato and Chiyoda wards, a naming dispute arose. Minato Ward wanted to keep "Tameike Station" referencing the old Tameike Stop on the Tokyo Toden Tameike Line (lines 3 and 6), which opened in 1905 and ran above ground along Sotobori Street until 1967. Meanwhile, Chiyoda Ward pushed for "Sannoshita Station," derived from the former line's Sannoshita Stop. This conflict between the two wards complicated the decision-making process. Ultimately, the matter was resolved by incorporating input from both sides and adopting a combined name.

The station facilities were inherited by Tokyo Metro after the privatization of the Teito Rapid Transit Authority (TRTA) in 2004.

Passenger statistics

In fiscal 2019, this station and Kokkai-gijidō-mae combined had an average of 150,922 passengers daily.
