Kamen Rider Fourze (仮面ライダーフォーゼ Kamen Raidā Fōze?, translated as Masked Rider Fourze) is the twenty-third entry of the Kamen Rider Series. It began airing on September 4, 2011, the week following the conclusion of Kamen Rider OOO,[1] joining Kaizoku Sentai GokaigerIcon-crosswiki and then Tokumei Sentai Go-BustersIcon-crosswiki in the Super Hero Time lineup.

Trademarks on the title were filed by Toei in April 2011[2][3][4] The series commemorates not only the Kamen Rider Series' 40th anniversary but also the 50th anniversary of spaceflight, which began with Yuri Gagarin's flight in 1961.[5]

The show's catchphrase is "Switch on youth 'cause we're going into space!" (青春スイッチオンで宇宙キター! Seishun suitchi on de uchū kitā!?),[6] referencing the Fourze Driver transformation belt which gets its various powers from devices called Astroswitches to conjure attachments to Fourze's limbs.[1][7]

As with the two previous series, the protagonist of Fourze made his debut in the annual summer film of the show's direct predecessor, appearing in Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals.


Fourze is written by Kazuki Nakashima, known for his screenplays of Oh! Edo Rocket and Gurren Lagann. The creature designer is Kia Asamiya, known for his artwork for the manga Martian Successor Nadesico and Silent Möbius. Koichi Sakamoto, known for his work on the American Power Rangers franchise, serves as the series' main director after his work on the Kamen Rider W films and several episodes of Kaizoku Sentai GokaigerIcon-crosswiki.


"Space, the limitless bounds of cosmic energy, and it's a wonderful world. This youth uses the Astroswitch to open the gates to the future. Space on your hands! Seize the youth and open your hands to grab the space!"

Amanogawa High School has become the center of strange happenings, and things only get stranger when the bad boy styled transfer student Gentaro Kisaragi attempts to make friends in his own unique way, reuniting with childhood friend and self-professed space travel otaku Yuki Jojima, all while gaining the ire of loner Kengo Utahoshi]. When the campus becomes overrun with monstrous constructs called Zodiarts, Kengo and Yuki attempt to use the strange devices they have found in the Rabbit Hatch lunar base that they access through a locker on an off-limits part of campus to fight them.

However, Gentaro interferes in their plans, in part due to Kengo's body unable to handle the strains of battle, and uses the devices to transform into Fourze.[8][9] Upon learning of other heroes called Kamen Riders, Gentaro creates the Kamen Rider Club whose membership includes Yuki, Kengo, the school's queen bee Miu Kazashiro, Miu's jock ex-boyfriend Shun Daimonji, garishly styled social butterfly JK and goth girl Tomoko Nozama.

Later joined by Ryusei Sakuta, a transfer student who transforms into Kamen Rider Meteor, and their teacher Mr. Chuta Ohsugi, the Kamen Rider Club and Kamen Rider Fourze learn of the Horoscopes, an evolved group of Zodiarts who have been orchestrating events on the school grounds to build up their ranks. As the battle escalates, the Horoscopes sets their motions to their final phase of their master plan before Kengo discovers his true existence.

Four short crossover episodes, collectively titled Kamen Rider Fourze × Crayon Shin-chan (仮面ライダーフォーゼ×クレオンしんちゃん Kamen Raidā Fōze × Kureon Shin-chan?), between Kamen Rider Fourze and Crayon Shin-chan were shown in each show's time slots during April 2012 to promote their respective series' new films: Kamen Rider × Super Sentai: Super Hero Taisen and Crayon Shin-chan: The Storm Called!: Me and the Space Princess. The characters will crossover in two episodes of each respective series. The story follows Shin-chan teaming up with Kamen Rider Fourze in order to go to space and rescue Shin's younger sister who had been taken to Planet Himawari to become its princess. The first and fourth episodes feature both anime and live-action while the second and third were entirely animated.

  • This season was originally going to have been about the Kamen Rider Club investigating various urban legends about Kamen Riders, and would have featured appearences of many past Kamen Rider actors, however, this was scrapped due to it being too similiar to Kamen Rider Decade.
  • This series contains the most used Ending Themes of the Neo-Heisei period, being used in almost every episode, except for some occasions. The others just use Ending Themes for rare occasions.
  • This is the first series since Kamen Rider Agito to not feature an original evil Rider/Anti-hero Rider in its films or respective show.
  • This is the only post-Kamen Rider Kuuga Heisei series to not include a Supporting Rider.
