Feudal Japan remains a possibility for the setting of a future Assassin's Creed game, Ubisoft has said. Assassin's Creed IV: Black Flag creative director Jean Guesdon told VG247 that feudal Japan is one of many time periods and locations that the publisher is considering as it moves the franchise forward.
“Feudal Japan remains--like numerous other time periods and locations--a possible future setting for the franchise because thanks to the Animus. The entire human history is our playground.”
The Animus is a fictional virtual reality machine from the Assassin's Creed franchise that has virtually transported players to destinations like the Renaissance (Assassin's Creed II), the American Revolution (Assassin's Creed III), and the Golden Age of Piracy (Assassin's Creed IV).
The most requested Assassin's Creed settings, according to Ubisoft, are World War II, feudal Japan, and Ancient Egypt. The publisher is also reportedly interested in a future entry set during the British Raj (colonial India), the setting of new comic Assassin's Creed: Brahman.
Ubisoft Toronto is currently collaborating on the next Assassin's Creed game, though details about this project have not been revealed. Ubisoft has launched a new core Assassin's Creed game every year since 2009.
