The main character Gentaro Kisaragi putting the word "Rider" on his finishers as his way to pay homage to Kamen Riders.
Fourze's Rocket Drill Switch and use of Drills for some finishers is a reference to the anime series Gurren Lagann, which Fourze writer Kazuki Nakashima was also the head writer of. Also, Gentaro's personality is very similar to that of Gurren dueteragonist Kamina.
This season was originally going to have been about the Kamen Rider Club investigating various urban legends about Kamen Riders, and would have featured appearences of many past Kamen Rider actors, however, this was scrapped due to it being too similiar to Kamen Rider Decade.
Kamen Rider Fourze is the second main Kamen Rider whose theme revolves around space. The first one was the Showa Rider, Super-1, thus, Fourze can be considered his Heisei counterpart. Like Super-1, the Fourze System was created for space travel.
