The JR East station consists of two platforms serving four tracks, with cross-platform interchange in the direction of travel between the Yamanote line (tracks 2 and 3) and the Keihin-Tōhoku line (tracks 1 and 4).
The Tokyo Monorail platforms are located to the west of the JR station in a separate elevated structure. Two side platforms serve a single track, with one platform used for boarding passengers, and the other platform used for alighting passengers.
Japan Airlines and All Nippon Airways operate check in services for domestic flights from Haneda airport along with ticketing facilities just outside the main Monorail entrances.
Daimon Station, served by the Toei Ōedo Line and the Toei Asakusa Line, is within easy walking distance, although some route maps do not mark them as an interchange. The 1-minute walk is fully signed and easy to locate. When arriving on a train from south train cars at the front of the train are closest to the exit to Daimon station.
