15-day trip

Hi everyone,

I have 2 questions and would appreciate any help :)!

1. does it make financial sense to purchase a 14-day JR Pass for the following trip trip:

2. Narita to Hiroshima (3 nights in Hiroshima)

3. Hiroshima to Kyoto (3 nights in Kyoto)
4. Kyoto to Osaka (2 nights in Osaka)
5. Osaka to the Five Lakes region (I know it's a bit imprecise...; 2 nights in the Five Lakes area)

6. Five Lakes to Tokyo (4 nights in Tokyo)

7. Is it easier to get to the Five Lakes area from Tokyo than from Osaka (I'm thinking about reversing the above itinerary)?

Thanks in advance!
