For folks wondering or impressed by the facial modeling. Here's a comparison of ingame and their actors. Everyone except Keiji Fujiwara were actually modeled, although you can tell they based Nishitani off of him regardless.
Without a doubt the best realistic facial modeling for asians in the industry. And it gets even better in 6.
Is that the detective from Yakuza 4 (not Tanimura, his superior) standing behind Kuze's actor?
