仮面ライダークウガ
is the title of the first installment of the 2009 editions of the long-running Kamen Rider Series of tokusatsu dramas. "Decade", as its title suggests, is the tenth of the Heisei Rider special anniversary Series, having begun with "Kamen Rider Kuuga" in 2000. Its protagonists are able to transform into not only their own unique, but also all of the previous 9 Heisei Kamen Rider phase 1 ""Kamen Rider Kuuga" - "Kamen Rider Kiva" (Also able to Heisei phase 2 "Kamen Rider W" - "Kamen Rider Zi-O"" with the Neo DecaDriver in twentieth of the Heisei Rider special anniversary series “"Kamen Rider Zi-O"”) and All Showa Kamen Rider, each of which have their own unique power that the Decade can access. It began broadcasting the week following the finale of "Kamen Rider Kuuga" and was featured in Super Hero Time alongside the 2009 edition of the Super Sentai Series, "Samurai Sentai Shinkenger". The series ties in with the arcade game "", with Kamen Riders Decade and Diend using cards resembling those used in the game to transform and access various weapons. Inspiration for this series was very likely to have been the fact that Toei had successfully ensured that the Kamen Rider series lasted a whole decade (2000-2009) without the show going into a period of hiatus which had always occurred since the franchise began in the 1970s. The series' English dub aired on October 20, 2012, 5:30 p.m. at Singapore's Okto Channel, Mediacorp. "Kamen Rider Zi-O", the last Heisei era series of 2018-2019, acts as a spiritual sequel, where both Decade and Diend play prominent roles as re-occurring side characters who are directly involved in that series plotline.
