Kamen Rider OOO/Trivia

• Dyeing for Your Art: Ryosuke Miura (who plays Ankh) had had his hair dyed and styled to play the role. His more "normal" hairstyle as Shingo Izumi is a wig.
• Fan Nickname: Japan has gone back to the tried and true method of numerical nicknames, giving Shintaro Goto the name "5103" (5=Go, 10=Tou, 3=San).
  • Some English-speaking fans call Goto "Cakebitch". Also "Broto", in reference to a fansub group using this as a "translation" for the times when Date addresses him as "Goto-chan".
  • Kougami is known as the "Cakeboss."
  • Barney for the Dinosaur Greeed.
  • "Lefty" for Ankh (Lost).
• Hey, It's That Guy!: Shingo Izumi, and Ankh's "human" form in a sense, was Beetle Sazer and the Tiger Orphenoch in Kamen Rider Decade.
  • You might recognize Takashi Ukaji, the man who played President Kougami, as Mon-chan from the 20th Century Boys films.
  • Akira Date was R5.
  • In #17, we meet the Chiefu... of a kendo club.
  • And in #27 Megumi is one of a pair of female bikers who fight the Yummy... and win.
  • In the 21 Core Medals movie, Yoshimune is played by Ken Matsudaira, who played the very same character in the 25-year Jidai Geki TV series Abarenbō Shōgun.
  • Isao Sasaki makes an appearance in the Let's Go Kamen Rider film as the adult version of one of the children Eiji and Kotaro Nogami befriend, who, oddly enough, is also the father of another one of those children.

  • Chiyoko's surname "Shiraishi" is written the same as Mako's in kanji (lit. "white stone").
    • Similarly, Hina is written with two characters from the name (Mikuru) Asahina, another Moe with famously Hidden Depths.
