When it comes to Triad movies, I'd say John Woo's Hard Boiled is definitely recommended.
The king of Yakuza movies is Takeshi Kitano. He's got more than a few under his belt. If you wanna see a really messed up Yakuza-related movie, you can give Ichi the Killer a shot haha.
Thank you !!! I'll check them !
Black Rain w/ Andy Garcia always shook me up..that's when I 1rst learned of the Yakuza,,,
