The Kerama Islands have many pristine beaches, and divers rate the coral and clear water off their coasts highly. There are two main islands, Tokashiki and Zamami, along with many more small, uninhabited islets. You can experience the best of the Keramas in a day trip or two from Naha. Eating and drinking establishments are scattered over the two islands, so you won't lack for sustenance.
