Kamen Rider Decade 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, it was also the final installment of the Heisei era's first phase. It began broadcasting the week following the finale of Kamen Rider Kiva and was featured in Super Hero Time alongside the 2009 edition of the Super Sentai Series, Samurai Sentai Shinkenger. 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.

Samurai Sentai Shinkenger is the title of Toei Company's thirty-third entry in its long-running Super Sentai metaseries of Japanese tokusatsu television series.

It incorporates elements from the Jidaigeki drama genre and Japanese themes and aesthetics. The catchphrase for the series is "Authorized by divine providence!!" .
