Full Metal Yakuza is a 1997 Japanese action and satire film directed by Takashi Miike. It was written by Itaru Era and based on a story by Hiroki Yamaguchi.
Originally released in Japan's direct-to-video market (V-Cinema), the film has gained more popularity because of the reputation of its controversial director.
Aspiring yakuza Kensuke Hagane, played by Tsuyoshi Ujiki, is killed by gang violence. His corpse winds up in the hands of a scientist who manages to keep him alive by replacing much of his body with cyborg parts.
Hagane has super-human strength and the scientist even reverses his impotency by giving him robotic genitals. Kensuke then searches for those responsible to get revenge.
