Let me start with this classic:
Dead Or Alive
Tagline: WARNING: This motion picture contains explicit portrayals of violence; sex; violent sex; sexual violence; clowns and violent scenes of violent excess, which are definitely not suitable for all audiences.
Plot: Without a home and feeling no obligation to Japanese society or Yakuza, Ryuichi (Takeuchi Riki) and his small group decide to make their own place by trying to take over the Shinjuku underworld and the drug trade from Taiwan. As they plan an all-out-assault on the remaining Chinese and Japanese mafia kings, only Detective Jojima (Aikawa Sho) stands between them and complete domination.
