The beloved robotic cat Doraemon is slated to return to the big screen in 2026 with a new animated film, “Doraemon the Movie: Nobita and the New Castle of Devil’s Undersea Castle.” This upcoming feature will mark the 45th installment in the legendary Doraemon movie franchise, promising a modern reimagining of one of the series’ most iconic adventures. While the film is confirmed for a 2026 release, specific guest voice actors and a precise premiere date, such as February 27, are yet to be officially announced.
A Deep-Sea Remake of a Classic Tale
“Doraemon the Movie: Nobita and the New Castle of Devil’s Undersea Castle” is a remake of the 1983 classic, bringing Doraemon’s thrilling deep-sea fantasy to a new generation. The film will be directed by Tetsuo Yajima, known for his work on previous Doraemon films, with Isao Murayama penning the screenplay. Yajima has hinted at an expansive underwater journey, promising “creatures and scenery never before seen.”
The storyline follows Nobita, Doraemon, Shizuka, Gian, and Suneo as their seemingly simple camping trip takes an unexpected detour into the mysterious Bermuda Triangle. Their adventure plunges them into strange undersea kingdoms, where they encounter powerful guardians and the fabled Devil’s Castle hidden deep beneath the waves. The narrative is expected to explore themes of courage, sacrifice, and the essence of true heroism amidst encounters with robot-controlled Atlantis and the enigmatic undersea people of Mu.
