The main station facade on the western side of the station is brick-built, surviving from the time when the station opened in 1914. The main station consists of 10 island platforms serving 20 tracks, raised above street level running in a north-south direction. The main concourse runs east-west below the platforms.
The Shinkansen lines are on the east (or Yaesu) side of the station, along with a multi-story Daimaru department store.
Underground are the two Sōbu/Yokosuka line platforms serving four tracks (five stories below ground level) to the west of the station; the two Keiyō Line platforms serving four tracks are four stories below ground some hundreds of meters to the south of the main station with moving walkways to serve connecting passengers.
The whole complex is linked by an extensive system of underground passageways which merge with surrounding commercial buildings and shopping centres.
