Here is an interview conducted by Game Trailers at Tokyo Game Show with Yakuza producer Masayoshi Kikuchi and director Jun Orihara.
The two discuss the story and characters of Yakuza 4 and go onto talk about the direction of the series as a whole. They also confirm that like Yakuza: Kenzan, Yakuza: Of the End is indeed a spin off and not cannon. They mention wanting to continue both the main ‘numbered’ series and the spin-offs.
Yakuza Sci-fi anyone? Punch Aliens in the face? Or a Yakuza Fantasy with Japanese mythology maybe? Punch real dragons in the face?!Ad:
