Kudanshita Station is served by the following three subway lines.
The underground station is built on three main levels, with the Tōzai Line platforms located on the 2nd basement level and the Shinjuku Line and Hanzōmon Line platforms on the 4th basement level.
The Tōzai Line platforms consist of two side platforms running approximately north-south. The Shinjuku Line and Hanzōmon Line platforms on the 4th basement level were originally configured as two sets of side platforms running approximately east-west parallel to each other. From 16 March 2013, the separating wall between these platforms was removed, allowing cross-platform interchange between platform 4 (Hanzomon Line Ageo-bound) and platform 5 (Shinjuku Line Shinjuku-bound).
