4. Onibi (1997)

Director: Rokuro Mochizuki

Often praised as director Rokuro Mochizuki’s masterpiece, Onibi artfully inserts romanticism and sexual desire into the otherwise brutal yakuza genre. Yoshio Harada plays Noriyuki Kunihiro, an experienced, I-don’t-give-a-fuck contract killer who completes a long stint in prison and returns to home with motivation to reform his life, settle down with a girl young enough to be his daughter, and work an honest job. Despite his calm posture, Kunihiro constantly struggles with his violent nature. Which, in true yakuza movie fashion, doesn't end well for him.
