Going to Okinawa for a month, what to look for?

I spent 3 years there from '97-'00 but didn't take my Z (big mistake). Now I'm going back for about a month and am curious what I could look for besides ChoroQ and Tomy Z car stuff at Toys R Us. I'm thinking a visit to Kinokuniya for some Nostalgic car magazines but am not really sure what else there may be to take advantage of. I know it's not the mainland where there are a ton of things to do but still, I'm just looking forward to hitting some restaurants and a vending machine or convenience store every 100 yards.
