Tetsuo II: Body Hammer is a 1992 Japanese science fiction horror film directed by Shinya Tsukamoto. It is a bigger-budget sequel to Tsukamoto's 1989 film Tetsuo: The Iron Man, utilizing similar themes and ideas as his first film (a Japanese salary man, played by cult actor Tomorowo Taguchi, finds his body transforming into a weapon through sheer rage after his son is kidnapped by a gang of violent thugs).
