JRPass

Hi there!

In general a 7 or 14 day rail pass is only worthwhile if you do a lot of travel (something like a return Tokyo <> Osaka usually makes a 7 day pass worthwhile for example). Based on your itinerary you won't spend enough to make a 7 day pass cost effective and so I recommend you purchase single JR tickets as needed. Please note that if you decided to do a day trip, such as a return to Hiroshima while you are in Kyoto/Osaka, then a 7 day rail pass will certainly be a good choice.

Hope this helps!
