He will be able to get on the internet - he should get a VOIP phone and get a number local to you, no long distance. They have broadband and all the amenities you can get here - plus some. (Naha Red Light district comes to mind...but I digress - d00d??).
Oki is AWESOME! Would love to be there myself right now.
Futenma is center/south end of the island, used to do touch and go's there when I was learning to fly. Used to have the best O-Club on the island.
Spent a couple of months TAD in NAHA with VMFA-115 after leaving Thailand in 1973, then a full tour just North of Futenma at Camp Butler in 1985. Of course no cell phones and internet then; but, LOTS OF FUN!! Back then the NAHA base was controlled by the Japanese Self Defense Forces;, now from what I understand, that location has been transferred over to an iinternational airport. Tell your son to check out the caves and caverns used by the Japanese in WWII during the Battle of Okinawa at "Suicide Cliffs". As stated, beautiful coral reefs for swimming, diving, and snorkeling. Lots of charter boat fishing and if interested in Martial Arts; one of the best places to be in the world to continue or begin ones training. The habu snake and mongoose fights were popular with millitary floks stationed on the island back then; not sure it's still legal today. Back then the Northern part of the island was the most rural area. As for the "RED LIGHT DISTRICT" Sean...I don't seem to remember too much about that area of the Island

...I SWEAR, I NEVER BEEN THERE...NOPE...NOT ME...Oh, I do seem to remeber being in a bar one time where the main attraction had something to do with the use of a HUGE Kirin beer bottle, a milk crate, and a roll of quarters

...But!, like I said...never been there...That's my story and I'm stickin to it
