Okinawa Beta?

Hi folks!

A friend and I are headed to Okinawa for two weeks at the end of December. I've got the guidebook written by Emmanuel Lacoste, which has great topos but is rather light on logistics like food/shelter/transportation. Any info anyone has to share on the following would be much appreciated!

1. What's the climbing like overall in the area, in terms of style/rock quality.
2. We'd love to get to meet some local climbers! Any advice on how to get in touch with the community?
3. What's the best way to cheaply stay on the island somewhere near the climbing?
4. Any unusual beta about gear/local ethics/poisonous animals/area closures/etc?
