Kamen Rider Series/Showa Series

The Shōwa period (昭和時代), or Shōwa era, is the period of Japanese history corresponding to the reign of the Shōwa Emperor, Hirohito, from December 25, 1926 through January 7, 1989.

The Kamen Rider Series started in the Shōwa period, the Heisei period started during the early episodes of Kamen Rider Black RX. Episode 11 of RX was delayed by one week following Emperor Shōwa's death.

Being completely absent from television during the 1990s, the Kamen Rider franchise was kept alive mainly by stage shows, musical CDs, and the Shin, ZO, and J movies, though many fans classify the movies as part of the Showa series as they treat Shotaro Ishinomori's passing in 1998 the pinnacle of the Showa era.

The Heisei revival of the Kamen Rider Series began with Kamen Rider Kuuga in 2000, this was noted in Kamen Rider Decade (2009), the tenth Heisei era series which initally united the first nine Heisei series, also giving focus on the Shōwa period despite being only 38 years since the start of the series due to Decade's position as the 25th Rider hero.
