Kamen Rider J

Everything About Fiction You Never Wanted to Know.

Kamen Rider J was a 1994 movie installment in the long-running Kamen Rider series.

Segawa Kouji is a reporter whose sister is carried off by the monstrous children of the alien Fog Mother to feed to her newly-hatched offspring. Kouji is given the mystical "J Power" to become Kamen Rider J and defeat Fog Mother before she can destroy mankind.

Footage from the movie was used in several episodes of Saban's Masked Rider, with J appearing only in faraway shots.


Tropes used in Kamen Rider J include:


  • Badass Biker: Kamen Rider, duh!
  • Crossover: With Kamen Rider ZO in the 8-minute short Kamen Rider World. Guest-starring monsters from several Kamen Rider installments and Shadow Moon.
  • Eldritch Abomination: The Fog Mother is a giantic cybernetic doomsday monster whose sole purpose for existing is to feed civilizations to her monster offspring. And that's even mentioning her true form.
  • Good Hurts Evil: The Fog Mother feels intense pain when J is first given his powers.
  • Green Aesop: It appears here and there, though the Fog Mother's plan doesn't revolve around it.
  • ~Hey, It's That Guy!~: Mochizuki Yuuta, best known for his role as Geki in Kyoryu Sentai Zyuranger plays Kouji.

  • Nature Spirit: A group of weird plant people who bring Kouji back to life as Kamen Rider J and task him with destroying the Fog Mother and her evil spawn, they state they're spirits of the Earth.
  • Never Live It Down: Thanks to Kamen Rider Decade, all future references to J make out his one-shot giant growth to be his primary ability.
  • Shout-Out: Kamen Rider J's name is a reference to the Japanese Pro Soccer League, better known as "J-League", which was founded a couple of years before the movie premiered.
