Hiroshima Station has two main entrances: the north — or Shinkansen — entrance, and the south entrance. Until the 1975 opening of the Shinkansen service, the Shinkansen entrance was called the "north entrance", and many local residents, newspapers, and real estate advertisements continue to refer to it as the "north entrance".
A pedestrian tunnel connects the area in front of the Shinkansen entrance to an underground plaza underneath the south entrance to Hiroshima Station. The tunnel includes many gift shops and restaurants, as well as two exits to Fukuya, one to the Hiroshima Station Tram Stop, one in front of the Hiroshima Higashi Post Office, and one directly in front of the south entrance to Hiroshima Station.
Elevator and escalator access is available for several of the entrances. Events are sometimes held in the large area of the underground plaza in front of the entrance to Fukuya.
Prior to 2017, the south entrance connected the plaza outside directly to the platform for track 1; passengers wishing to access any other track from the south entrance were forced to first enter onto the track 1 platform and then ascend to the concourse above. Similarly, passengers wishing to exit the south entrance after arriving on any other platform were forced to descend from the concourse level to the track 1 platform to exit. To eliminate this bottleneck, the concourse level was expanded and a new south entrance was added slightly to the east of the old one. This design, which is standard for major Japanese rail stations, enables direct access to the concourse level from the south entrance. The new south section of the station was opened on May 28, 2017, and the old south entrance is now under construction. The new south exit and Hiroden platforms will be completely rebuilt. It is planned to reopen in 2025. The south exit is still usable, but often gets rerouted.
Platforms
The Shinkansen station has two island platforms which serve a total of four tracks. The non-Shinkansen lines use three island platforms and one side platform serving eight tracks.
Construction is underway for a streetcar system to be installed on the second floor of the JR Hiroshima Station Building, which will be newly opened in 2025.
Routes
From Hiroshima Station, there are four of Hiroden Streetcar routes on the Main Line.
