Brother (2001)

Abandoned by the brotherhood of his yazuka clan, gangster Yamamoto flees a crime war in Tokyo and ends up in Los Angeles looking for his long lost brother. Alone and with a new identity, Yamamoto finds himself frustrated by foreign surroundings but soon strikes up a friendship with Denny, an up-and-coming black hustler, with whom he had an earlier violent run-in. They team up to take over the drug turf of East L.A. Before long, Yamamoto's gang grows in number, business flourishes and money flows. Yamamoto and his boys now wear expensive suits, cruise in limousines and work out of lofty offices. As success breeds jealousy, Yamomoto joins forces with rival Japanese crime lord, Shirase. It becomes an all-out war without sanctuary for anyone. As things heat up, Yamamoto learns that only Denny has really caught on to the yazuka code of brotherhood...
