It is also connected by an underground passageway from the western end of the Hanzōmon Line platform to Akasaka-mitsuke Station on the Ginza and Marunouchi lines.

The station consists of three island platforms, each serving two tracks.

The station opened on October 30, 1974, as part of the original section of the Yūrakuchō Line between Ikebukuro and Ginza-itchōme.

The Namboku Line platforms opened on September 30, 1997.

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