Name's the Same: There is slight difference in how the names are punctuated but the first enemies Kamen Rider fights are called Spider Man and Bat Man. (Less so in Japan, where the monster names are in Japanese, but the comic book heroes' names are in English.)
Promoted Fanboy: Given the series' status as a Long Runner, more and more actors playing Heisei Riders grew up watching Showa and early Heisei Riders. The greatest among these has to be Ryouta Murai, who grew up watching Kuuga, and got to be Kuuga for Kamen Rider Decade.
Hey, It's That Place! - Some locations are not only repeated in the same season, but occasionally will repeat in multiple seasons.
This might as well as be called "Hey! It's that Gravel Pit!", as it applies to Tokusatsu, Because both Kamen Rider AND it's sibling Super Sentai have, for the past few years, made use of the same gravel pit for every big mass battle they have, to the point where Hikonin Sentai Akibaranger, a parody of Super Sentai intended for the adult periphery who grew up watching Sentai as kids, made use of it in their first episode.
There is also a particular rooftop that has seen use in basically every Heisei-era Rider series.
