My family is planning to vist Hiroshima and Miyajima then Kobe travelling from Tokyo. We are thinking of a 3-4 days trip but not sure what is the best itinerary for such combination. Should be go straight to Hiroshima first then back to Tokyo from Kobe? or should it be the other way around? Is Osaka a better base to do this journey? What types of transporation are available? I would appreciate any help or ideas that I can get.
