Well, I think if people in the know will share, it will have a lot of interest. But its my understanding that moving to Okinawa at the present time just might be a good time. The reason why I feel is that some things just might be negotiable, like rents with no key deposits.
I'd like to find out also what bus rides cost. I have plans to be in Okinawa pretty soon, so Square, I'll be on the look out for what things will be costing me. So check back in March or April of this thread if all goes well for me.
I'm interested in renting a run down house actually out in the boondocks, but haven't got any help on that yet.
David and Snow should be able to give you a rundown on things. I, from my own experience living in Yamaguchi, transportation would be probably up on the list and for you I would guess the schools would be up on the list.
I don't know of any Japanese forums that deal with Okinawa.
I would suggest to you go to this site:
Free virtual language exchange site using Skype by Dickinson College | The Mixxer
and look for someone that can help you out, you might find someone on Okinawa.
Look for someone that just joined the site, because the people that been on there a while, well you'll be wasting your time trying to get them to write to you.
It's a site put out by a university. Good site. All professional and yes, its free.
