One of the most important names in contemporary Japanese cinema, Shinya Tsukamoto has done groundbreaking work in arousing international attention for Japanese film. When his still powerful, independently made, black-and-white Tetsuo: the Iron Man (1989) toured an unprecedented number of festivals in the late 80s and early 90s, many western eyes turned eastward with renewed interest.

  Hiruko - The Goblin
  "Letztlich weder Meisterwerk noch Kunst, doch allemal von Nutzen seinen niederen Instinkten zu frönen. "Hiruko", ein deftig trashiger Monsterromp für Freunde blutverspritzer Freakshows mit zwinkerndem Blick auf das Genre."
  A Snake of June
  Das Kino der Gefühle ist immer auch ein Kino der Extreme. – Im Falle Tsukamoto, ein Purgatorium in tristem Blau. – Besonders sehenswert.

The "light" version of "Tetsuo - the iron man" would be "Electric Dragon 80000V" by Sogo Ishii.
From imdb.com: but there's less of the "biting down on aluminum foil" effect you get from Tetsuo.

I completly agree with midnighteye.com: Words cannot begin to describe this film. A 55-minute hyperkinetic descent into electro-charged punk madness, set to an eardrum-shattering industrial punk/noise soundtrack, Electric Dragon 80,000 V transcends film to become an overwhelming, all-immersing experience. Just hope and pray that you still have all your brain cells after you emerge from it.
