Doraemon the Movie: New Nobita and the Castle of the Undersea Devil is a 2026 Japanese animated science fantasy film and the 45th entry in the long-running Doraemon feature film series. Directed by Tetsuo Yajima with a screenplay by Isao Murayama, it serves as a direct remake of the 1983 classic Doraemon: Nobita and the Castle of the Undersea Devil, which was itself based on one of Fujiko F. Fujio's Doraemon Long Stories manga. The remake updates the beloved underwater adventure with modern animation techniques while retaining the core story of Nobita and his friends discovering the lost kingdom of Mu and confronting the mysterious Devil's Castle.
The original 1983 film holds a special place in Doraemon history as the fourth feature film and the first directed by Tsutomu Shibayama, who became a defining voice for the franchise's cinematic outings. The story follows the gang as they use Doraemon's gadgets to camp on the ocean floor, where they encounter El, a young soldier from the underwater Mu Federation, and learn of a terrifying mobile fortress controlled by a rogue computer system. The 2026 remake reimagines this adventure for a new generation, with updated character designs and presumably expanded world-building, though it remains faithful to the spirit of Fujiko F. Fujio's original vision.
Like many Doraemon films, the story balances whimsical gadget-driven fun with surprisingly mature themes. The original tackled nuclear anxiety and the perils of artificial intelligence, topics that feel even more prescient today. The underwater setting provides a visually stunning backdrop, from vibrant coral reefs to eerie sunken ships, and the introduction of the Mu civilization adds a layer of mythological intrigue. The remake likely amplifies these elements with modern CGI-enhanced animation, a hallmark of recent Doraemon films.
As part of the Doraemon Movies collection, this film continues the tradition of remaking classic entries from the Showa-era series with contemporary production values. Previous remakes in the franchise, such as Nobita's Dinosaur and Nobita's New Great Adventure Into the Underworld, have been well-received for honoring their source material while introducing the stories to younger audiences. New Nobita and the Castle of the Undersea Devil follows in that tradition, ensuring that one of Doraemon's most memorable aquatic adventures remains accessible and visually spectacular for fans old and new.
The Doraemon film series is a long-running collection of animated feature films based on the beloved manga and anime franchise created by Fujiko F. Fujio. Beginning in 1980 with 'Doraemon: Nobita's Dinosaur', the series has become an annual tradition in Japanese cinema, with new installments released almost every spring. These films typically follow the titular robotic cat from the 22nd century and his young friend Nobita Nobi as they embark on extraordinary adventures across time, space, and fantastical realms, often utilizing Doraemon's ingenious gadgets from his four-dimensional pocket. While the original manga and television series focus on everyday slice-of-life scenarios, the movies expand the narrative scope, introducing higher stakes, epic journeys, and environmental or moral themes that resonate with family audiences. The series has evolved through different eras of animation and storytelling, with many early films being direct adaptations of manga storylines, while later entries explore original plots and even reimaginings of classic tales. This enduring collection has cemented Doraemon as a cornerstone of Japanese popular culture, with the films consistently drawing large audiences and contributing to the character's status as an official cultural ambassador of Japan.
