Pacing My Japan Trip - What do you recommend for stay times?

Me again! Working out my scheduling.

For days stayed, do you think this is enough time, too much time, in each area? We wanted more time in Okinawa but our hotel resort we got booked with points didn't have much availability, so we thought we'd wrap up the trip with some beach time and the Aquarium there. Should I shorten our stay in Osaka for more time in Tokyo? (Or vise versa?)

Do you also recommend we move hotels in Tokyo and stay in a different part in Tokyo for part of our Tokyo stay, or is it pretty easy to navigate Tokyo by train once you're there?
