Tittle basically says it all. Boingboing did a review that basically included Yakuza members sitting down, playing the game and giving their impressions. It's pretty hilarious. 
One of my favorite parts are when they talk about the fashion in the game: 
"M:What's the deal with Kiryu's scarlet red shirt? He's supposed to be a former boss of the Inagawakai--and he dresses like a chinpira (low level yakuza punk). He's a yakuza, not a host."

That was pretty interesting. I've always wondered what real gang members think of mafia type games.

M: What's the deal with Kiryu's scarlet red shirt? He's supposed to be a former boss of the Inagawakai--and he dresses like a chinpira (low level yakuza punk). He's a yakuza, not a host.

S: You got your salaryman in there, the delinquent school girl and her sugar daddy, Chinese people, and even those Nigerian touts. What's with all the fucking gaijin (foreigners) in the area anyway? It used to be just Japanese, Koreans and Chinese.
M: Don't say gaijin. Say Gaikokujin. It's more polite. Jake's a gaijin.
S: Yeah, I forget sometimes. What's with all the fucking gaikokujin in Kabukicho anyway? 

M: A real fight--it's short and it's brutal. Over in a minute. Nobody goes around trading blows and crap like that. Usually the first guy to punch wins.
K: I like that you can grab things like ashtrays or billboards and beat the crap out of the punks bothering you. Or smash their faces into car windows. That's what you'd really do in a fight, grab something and use it as a weapon.

M: If they wanted to make it realistic, he'd pull out a gun and shoot it and miss! Or the damn thing wouldn't fire. That would be realistic. (They all laugh).
K: Shooting people sends a message.
M: So does shooting anything. Shooting people gets you sent to jail.
K: That's part of the job description.  

M: Kiryu is the way yakuza used to be. We kept the streets clean. People liked us. We didn't bother ordinary citizens. We respected our bosses. Now, guys like that only exist in video games.
S: I don't know any ex-yakuza running orphanages.
K: There was one a few years ago. A good guy.
M: You sure it wasn't just a tax shelter?
K: Sure it was a tax shelter but he ran it like a legitimate thing. You know.  

Awesome

My god, this is freaking incredible, awesome find!

Awesome, but as with any of this i can't help but question the legitimacy.

Now that is what you call journalism.

Ye i thought about that aswell. As awesome as it may seem... i have my doubts. ( Why would a site that reviews games get access to the yakuza and on top of that make them review a game... ) "
