Shōgun is a 1975 novel by James Clavell. It is the first novel (chronologically speaking) in the author's Asian Saga. It is set in feudal Japan in the year 1600 some months before the critical battle of Sekigahara, and gives an account of the rise of the daimyo "Toranaga" (analogous to the real-life Tokugawa Ieyasu) to the Shogunate, seen through the eyes of an English sailor whose fictional heroics are loosely based on William Adams' exploits.
The novel has been adapted as a groundbreaking television miniseries, a Broadway musical, and several computer games.
The television series, Shōgun (TV miniseries), was shown in 1980. Nine hours long (twelve, including advertisements), it was broadcast over five nights. It starred Richard Chamberlain, Toshiro Mifune, Yoko Shimada, and John Rhys-Davies. It was also edited into a two-hour theatrical release, and a 5-disc DVD release in 2003.
