The original Shōgun was a rare phenomenon. More than 1,200 pages and 400,000 words in length, it proved stunningly successful, staying on the best-seller list for more than 30 weeks and selling millions of copies. The 1975 novel presented a fictionalized account of a real event: the arrival of an English pilot, William Adams, to Japan in 1600. Clavell reimagined the story, giving his hero (whom he renamed John Blackthorne), a starring role in the archipelago’s turbulent domestic politics in the months leading up to the climactic battle of Sekigahara, which brought more than a century of constant warfare to a final end.

Some historians criticized Shōgun as a text rife with errors and national stereotypes. But others like Henry Smith championed the book, arguing that it conveyed “more information about Japan to more people than all the combined writings of scholars, journalists, and novelists since the Pacific War.”
