Frequently asked questions
How much are expressway tolls from Osaka to Hiroshima?
Driving the Sanyo Expressway from Suita IC (Osaka) to Hiroshima IC (about 335 km) costs roughly ¥7,510 to ¥8,200 with an ETC card on weekdays, or around ¥5,450 on weekends with the 30% ETC discount.
Can you avoid the one-way car rental fee between Osaka and Hiroshima?
Yes! Instead of dropping the car in Hiroshima (which adds an ¥18,000–¥28,000 one-way fee), cross the Shimanami Kaido bridges from Onomichi to Imabari in Shikoku, visit Matsuyama or Takamatsu, and return to Osaka/Kobe via the Seto-Ohashi Bridge or Awaji Island with zero drop-off fee.
Can you take a rental car onto Miyajima Island?
While car ferries operate between Miyajimaguchi and Miyajima, streets on Miyajima Island are narrow and mostly pedestrianized. It is much faster and cheaper to park at Miyajimaguchi on the mainland (¥1,000–¥2,000/day) and take the 10-minute passenger ferry (¥200).
