Swallowtail Butterfly (1996)

both films are about Japanese fear and hatred of foreigners invading Japan. In "Kamikaze Taxi" the xenophobic behaviour is directed towards nikkei (the male lead is Japanese-Peruvian). Both are about yakuza and power struggle as well.

The same director, very good atmospheric music.
There is something that applies to every Shunji Iwai film.
