Yakuza 3 is unabashedly Japanese, so much so that mainstream Western audiences may be unlikely to relate. Nagoshi explains in the video that as a fan of Japanese cinema, he intended on "using a Japanese style to express [human drama]" in the game. "It might feel new to the Western market, but to the Japanese market it's something we grew up on, so we're used to it."
No wonder the Yakuza franchise has earned its cult status in the West. While its use of Japanese camp may be confusing to many, that's precisely what English-speaking fans love about the franchise. Thankfully, it won't be too much longer until everyone will be able to play Yakuza 3 ... and understand what's going on.
