This extensive travel book by lecturer and Okinawa expert Robert Walker is billed as "the first comprehensive guide to the entire Ryukyu Island chain." With 25 years experience traveling throughout the region's 150-islands Walker has amassed a huge amount of information — condensed here into 290 pages that cover everything from useful Japanese terms to the activities each island is known for. With key destinations, transportation information and places to stay even on the smallest of islands, all of the necessary information is provided without overwhelming the reader.
