2026 Doraemon Film Remakes Nobita and the Castle of the Undersea Devil

Pokémon XY's Tetsuo Yajima helms film penned by Witchy Precure!'s Isao Murayama

A website opened on Saturday to announce the 2026 Doraemon film, Eiga Doraemon: Shin Nobita no Kaitei Kiganjō (Doraemon the Movie: New Nobita and the Castle of the Undersea Devil). As the title indicates, this 45th 2D anime film (not counting the 3D CG Stand By Me Doraemon films) remakes the classic 1983 film Doraemon the Movie: Nobita and the Castle of the Undersea Devil.

The tagline on the teaser visual reads, "10,000 meters below sea level. On this Earth, there lies a world no one has yet to uncover."

Tetsuo Yajima (Pokémon the Movie: Secrets of the Jungle, Pokémon the Movie: The Power of Us, Pokémon XY) returns after directing episodes of the Doraemon television anime and contributing in other capacities to Doraemon the Movie: Nobita's New Great Adventure into the Underworld, Doraemon the Movie: Nobita and the Steel Troops: The New Age, and Eiga Doraemon: Nobita no Chikyū Symphony. Another veteran of the television anime, Isao Murayama (Witchy Precure!, Star Twinkle Precure, Bakugan) wrote the new film's screenplay.
