Comprehensive and well-researched, this definitive book of the history of the Ryukyus is able to capture the essence of the Okinawan people. Their trusting and peaceful nature; strength and tenacity through typhoons, poverty, disease, and invasion; and grace and adaptability are all in evidence as they juggle dual allegiances to China and Japan; interact with interlopers and bellicose outsiders including Christian missionaries and Commodore Perry; and adjust to the post-WWII American presence, Reversion, and transition to a tourist economy.
While my copy was revised in 2000, it was done so in a patch quilt fashion. The Afterward intersperses updates, notes, and ends with error corrections. There is no map at the front of the book nor a legend to advise (especially younger readers) that Formosa is now Taiwan, Siam is Thailand, etc. Finally, for readability, consider removing the umlauts from words such as cooperation, and use current spellings for sceptic (skeptic), despatch (dispatch), and others throughout the book.
I would suggest that the next rewrite undergo a thorough feeding through a word processor to incorporate revisions, as well as another update for the past decade to incorporate status changes such as the movement afoot for autonomy and independence.
