FX/Hulu’s new historical epic series, Shōgun, based on the bestselling 1975 novel by James Clavell, has met with both popular and critical acclaim since its February premiere, drawing over 9 million views across all platforms in the first six days alone.

But it’s also a visually stunning achievement that brings 17th-century feudal Japan to vivid life, thanks to masterful special effects that have been woven in so seamlessly, it can be challenging to distinguish between the CGI and the real footage.

The author changed the names of all the main characters, purportedly to “add narrative deniability,” and despite some inevitable inaccuracies and authorial liberties, the novel is breathtaking in scope, chock-full of encyclopedic period details.

“In sheer quantity, Shōgun has probably conveyed more information about Japan to more people than all the combined writings of scholars, journalists, and novelists since the Pacific War,” an editor named Henry Smith wrote in 1980.

A nine-hour miniseries adaptation of Shōgun ran over five nights in September 1980, starring Richard Chamberlain as John Blackthorne and Toshiro Mifune as Lord Yoshii Toranaga, the fictional characters based on Adams and Tokugawa, respectively.

There is a scheming local lord, Kashigi Yabushige (Tadanobu Asano) trying to play both sides; a charming Spanish sailor named Vasco Rodrigues (Nestor Carbonell, Lost) who befriends Blackthorne; and the alluring translator, Toda Mariko (Anna Sawai), who finds herself torn between her loyalty to Toranaga and her Catholic faith—not to mention a growing attraction to the foreign Anjin.
