Trivia / Chikyuu Sentai Fiveman

  • Cast Incest: Ryohei Kobayashi and Keiko Hayase, who played the twins Fumiya and Remi, dated on the show and later married in real life.
  • Dawson Casting: All of the main actors were roughly the same age as their characters except for Ryohei Kobayashi (Fumiya, the youngest of the siblings), who was actually the second oldest in the main cast next to Toshiya Fuji (Gaku) and six years older than his on-screen twin/real-life wife Keiko Hayase (Remi)
  • Name's the Same: The evil Gingaman team has nothing to do with the later Super Sentai team of the same name.
    • The Hoshikawa siblings are not related to Ryū Hoshikawa/Dyna Black from Kagaku Sentai Dynaman.
    • Also, Five Pink is not to be confused with the similarly named ranger Pink Five from Choudenshi Bioman.
  • What Could Have Been: Ryohei Kobayashi was given the role of Fumiya as compensation after he auditioned for an unmade follow-up to Kamen Rider Black RX.
