It is a set of two stations connected by an elevated walkway about 100 m long.

The TWR station is served by the underground TWR Rinkai Line between Ōsaki and Shin-Kiba, with many through trains continuing to and from the East Japan Railway Company (JR East) Saikyō Line and Kawagoe Line.

The monorail station has two unnumbered elevated side platforms, and two sets of ticket barriers.

The TWR station has an underground station concourse on the basement ("1BF") level, and a single island platform on the third-basement ("3BF") level, serving two tracks.
