10 nights 11 days itenary

Hi

We are 2 adults and a child visiting Japan in June. Land at Narita and want to do following:

Day 1-3
Tokyo

Day 4
Hakone

Day 5-6
Kyoto

Day 7-8
Hiroshima and Miyajima

Day 9-10
Tokyo Disney

Is this too hectic an itenary? Would the JR pass be beneficial to get? Is there a different way of doing this itenary to get maximum scenery and exposure to culture?

Thanks
