When I think Okinawa I think goya (that's "bitter melon" in English, although it's not a melon!) and shikuwasa (no real good English word for that, it's a type of citrus fruit)... I also think of some other food (but that's for another clipart, another time) but I thought I'd provide this here for some sort of Okinawa symbol.
