The anime series *Shōnen Ninja Kaze no Fujimaru* features Japusai as its main antagonist, a master of fire techniques pursuing the Ryuen Book. The character name Fūma Jūhōsai does not appear in this series. The surname Fūma exclusively references the unrelated *Lupin III* film *Lupin III: The Fuma Conspiracy*, which shares no connection with *Shōnen Ninja Kaze no Fujimaru*. No additional official media for the series—including seasons, movies, OVAs, or spin-offs—includes a character named Fūma Jūhōsai.
