I'll be taking a 4 day trip in the Hiroshima area the week after the next. I'll be flying into and out from Kansai Airport.
Itinerary briefly as follows
Day 1 - Miyajima
Day 2 - Miyajima to Hiroshima
Day 3 - Hiroshima to ? Akiyoshidai (to Shin Yamaguchi) and back
Day 4 - Hiroshima back to Kansai airport
Would it be worthwhile buying a JR pass under the circumstances?
