Dear JR expert,
I am really interested in buying JR pass for my 5 days trip between Okayama and Hiroshima. And I am wondering if I could use my JR pass for the Sinkansen between Okayama and Hiroshima? How do I reserve seats with JR pass and do I have to pay extra fee?
Thank you so much for your time. I am looking forward to hearing from you soon.
Mundokiwi.
