Kamen Rider (仮面ライダー Kamen Raidā?, Masked Rider) is a weekly science fiction story created by Japanese manga artist Shotaro Ishinomori. It debuted as a tokusatsu television series on April 3, 1971, and ran until February 10, 1973, airing on the Mainichi Broadcasting System and NET TV (now TV Asahi). A manga adaptation was also featured in Shōnen Magazine around the same period. The series has evolved into a franchise with many sequels. The cultural impact of the series in Japan resulted in astronomer Akimasa Nakamura naming two minor planets in honor of the series: 12408 Fujioka, after actor Hiroshi Fujioka, known for his portrayal of Takeshi Hongo/Kamen Rider 1, and 12796 Kamenrider, after the series itself.
