using jrp on my trip

Hello,

Yes you can take JR all the way. But please note that Tokyo to Kinosaki will take 5-5½ hours which is very rough. To Hiroshima will take another 5 hours. You will barely make a 7 day pass pay off.
You can see regular fares, routes and schedules on Hyperdia.
Under "More Options", be sure to uncheck the Nozomi box since you can't ride that train using the pass.

If you're definitely going to Kinosaki, you might get a Kinosaki onsen day pass.

Good luck.

many thks for infos , do you think better to reserve seat in that high season ..!??

thks aga in

Hi,
I don't see why not - it's free with the pass.

Good luck.
