Samurai! is a 1957 autobiographical book by Saburo Sakai co-written with Fred Saito and Martin Caidin. It describes the life and career of Saburo Sakai, the Japanese combat aviator who fought against American fighter pilots in the pacific theater of World War II, surviving the war with 64 kills as one of Japan's leading flying aces. Caidin wrote the prose of the book, basing its contents on journalist Fred Saito's extensive interviews with Sakai as well as on Sakai's own memoirs.
