Hiroshima has an extensive tram service that will get you almost anywhere you want to go for a flat fare of ¥150 (¥100 on the short route 9). There’s even a tram that runs all the way to Miyajima port (¥270). If you have to change trams to get to your destination, you should ask for a norikae-ken (transfer) ticket. Pay when you get off.
Two bicycles are available for rent at Nippon Rent-a-car (264-0919; 3-14 Kojin-machi; 24hr), four blocks southeast of the station. Bike rental costs ¥263/735 per two hours/day.
