It has been revealed that the 45th film in the Doraemon the Movie series, based on the popular anime Doraemon created by Fujiko F. Fujio , will be titled Doraemon the Movie: Nobita and the Castle of Nobita's Undersea Rock and will be released in 2026. It is a remake of the long-loved Doraemon the Movie: Doraemon and the Castle of Nobita's Undersea Rock, which was released in 1983, and marks the rebirth of this classic after 43 years.
The film will be directed by Yajima Tetsuo, who has worked on storyboarding and directing for the Doraemon TV anime, as well as on the 2007 release of Nobita's New Great Adventure into the Underworld: The Seven Magicians, the 2011 release of Nobita and the New Steel Troops: Angel Wings, and the 2024 release of Nobita and the Earth Symphony. This will be Yajima's first time directing a Doraemon movie. The script will be written by Murayama Isao, who has worked on numerous episodes of the Doraemon TV anime. This will also be Murayama's first time working on a Doraemon movie.
Director Yajima commented, "10,928 meters. The deepest depths mankind has ever reached. And even further -- let's go on an adventure with Doraemon and his friends! I'm sure there will be creatures and scenery that no one has ever seen before. Doesn't it get you excited just thinking about it? The choices and decisions they will have to make there may trouble them. But there will surely be 'unexpected answers' hidden within. To a deep sea world that no one has ever seen before. I look forward to the day when we can experience it together on the big screen."
A teaser visual depicting Doraemon and friends standing on the surface of the water was released with the tagline, "10,000 meters below the sea. There is a world on Earth that no one has discovered yet." The figure of a mysterious boy is also visible on the surface of the water, and beyond him looms a huge, unknown underwater castle of demon rock.
A Teaser trailer has also been released. The veil of the mysterious deep sea is gradually lifted, revealing a glimpse of the magnificent underwater world. A sunken ship silently sinking in the depths of the ocean, a mysterious giant creature suddenly appearing before Doraemon and his friends, and a shining, fantastical underwater city are vividly depicted. At the end, an unidentified entity appears, standing in Doraemon and his friends' way.
