Using Japan Rail pass for 12 days

Hello there,

I have made a list of ticket prices below to see if the JR Pass would be useful.

Osaka - Hiroshima ¥ 10,230
Hiroshima - Miyajima (return) ¥ 1,140
Hiroshima - Uno, for ferry to Naoshima ¥ 6,350
Uno - Okayama ¥ 580
Okayama - Kinosaki ¥ 6,560
Kinosaki - Kyoto ¥ 5,680
Kyoto - Tokyo ¥ 13,600
Tokyo - Narita Airport ¥ 3,020

For a total of ¥ 47,160. The 14 day JR Pass is ¥ 46,390 so you would be able to make small savings. However the JR Pass can also be used for local travel in Tokyo, Osaka and to a limited extend in Kyoto, adding more. Also the JR Pass will function as a single ticket for all your travel. Making it easy to get around!

Hope this helps,
Daniel
