As fans prepare for the long-awaited return of HBO's Westworld, showrunners Jonathan Nolan and Lisa Joy have revealed that one episode set in Shogun World will be almost entirely in Japanese.

The Season 1 finale had the big reveal that the robotic hosts of Delos weren't alone in the world, as Thandie Newton's Maeve and her escape party ended up in a mysterious location with the initials "SW." Because of its Japanese warriors, many viewers presumed "SW" stood for "Samurai World" until Nolan and Joy clarified it's actually Shogun World. Picking up where Season 1 left off, some of the characters will spend plenty of time in this dangerous new land.

Set mainly in the Edo Period between 1603 to 1867, Shogun World will have even fewer rules, and more violence, than the Wild West of Westworld. Speaking to Entertainment Weekly, Nolan cited the bloody Sonny Chiba movies among his major influences for the new park, promising that one particular episode will be heavily focused on Shogun World.

"It wasn’t just about gore, it’s also about being immersive," he said. "We wanted to feel like our story dropped into a totally different world. Basically, we have a whole episode in Japanese."

While the name of the show is still very much Westworld, Season 2 will take on a bigger challenge, especially with an episode mostly in a different language. Nolan and Joy explained there were opportunities to turn to Michael Crichton's 1973 movie and its 1976 sequel to find another park for Season 2, but instead of opting for Medieval World or Roman World, the showrunners wanted something new.

When Westworld wrapped Season 1, Ingrid Bolsø's Berdal Armistice found herself trapped in Shogun World, while Maeve was last seen leaving the train she tried to escape on and heading towards the theme parks. The Westworld trailers have shown that Maeve will don a kimono and head back into Shogun World, while newcomers to the show will be Pacific Rim's Rinko Kikuchi as a geisha and Lost's Hiroyuki Sanada as a samurai.

Season 1 was already one of the bloodiest titles on TV, but the executive producers promise that is only the beginning of what's in store for the guests in the parks. Again turning to the trailers, bodies are seen lying around as security teams try to wrangle Westworld back from Dolores and the rest of the hosts' uprising. The big question still remains though, will the robots of Shogun World follow suit or can Delos restore order?

Debuting Sunday, April 22, at 9 p.m. ET/PT on HBO, Westworld Season 2 stars Evan Rachel Wood, Thandie Newton, Rodrigo Santoro, James Marsden, Jeffrey Wright, Tessa Thompson, Luke Hemsworth, Jimmi Simpson and Ed Harris.
