Tatsuhito, a cop, pursues Chinese warlord Wang through the underworld of Shinjuku and over to Taiwan.

Shinjuku Triad Society

The story follows a trio of Japanese youths of Chinese descent who escape their semi-rural upbringing and relocate to Shinjuku, Tokyo, where they befriend a troubled Shanghai prostitute and fall foul of a local crime syndicate. Like many of Miike's works, the film examines the underbelly of respectable Japanese society and the problems of assimilation faced by non-ethnically Japanese people in Japan.
