This trip mainly involved staying in Hiroshima. Hiroshima Station is small and the routes are straightforward, making it very convenient and easy to find the platforms. We used the Hiroshima Rail Pass to travel on the Sanyo Shinkansen to Hakata, Okayama, and Miyajima, arriving at our destinations at lightning speed. We completed a round trip between Hiroshima and other cities in a single day, achieving our goal of visiting multiple cities in one trip. I was really happy with this Rail Pass and would highly recommend it!
