As noted in the Transportation Guide, due to the limited number of shuttle buses operating from the South Exit of JR Itsukaichi Station, it is expected that buses may become full at certain times (Temporary Shuttle Bus Timetable).

If you are in a hurry, please use a regular bus, take a taxi from the North Exit of JR Itsukaichi Station, or transfer to the Hiroshima Electric Railway Miyajima Line and get off at Rakurakuen Station, then walk to the venue.
When walking, please take precautions against heatstroke, such as using a parasol.
