The Ginza Line station originally opened as an
island platform serving two tracks, but overcrowding prompted the construction of a
side platform serving Shibuya-bound trains in 1984. The island platform currently serves only Asakusa-bound trains, and the Shibuya side of the platform is fenced off. The Tōzai Line station consists of an island platform serving two tracks, while the Asakusa Line station consists of two side platforms with two tracks between them. At the Asakusa line station, passengers must choose their direction before passing through the ticket gates.
