Sorry for the long gap in response and thanks for all the info. We've decided to spend 1 week in Okinawa, but almost entirely on Zamami. And a couple of days in Naha. My wife who can is Japanese found a hotel & dive shop on Zamami that can speak enough English and is OK with me. I'm going to try [really hard] to check out the whale shark dive while on the main island, but not sure if I'll have time. Thanks again for your help. After the trip I'll write a trip report for other potential Scubaboarder's considering Japan.
