Plot

Disagreeing over where to go camping during summer vacation, Nobita and his friends decide to camp in the middle of the ocean at Doraemon's suggestion. Using their secret gadgets, the "Underwater Buggy" and the "Tekio Light," the five enjoy their undersea camping adventure, encountering various creatures.

After discovering a sunken ship, they meet a mysterious young man named El. He turns out to be an "undersea person" who lives in the Mu Federation, which spreads under the sea. The undersea people hate people on land and cannot trust Nobita and his friends. Then they receive news that "Devil's Rock Castle...has begun to move!!" What exactly is this "Devil's Rock Castle" that the undersea people fear...?

With faith in their friends, they set off on a great adventure that will determine the fate of the Earth.

Production

Planning and Staffing

Tetsuo Yajima was selected as the director. He has been largely involved in the Doraemon (2005 TV series) and in the production of films such as Nobita's New Great Adventure into the Underworld (2007), Nobita and the New Steel Troops: Winged Angels (2011), and Nobita's Earth Symphony (2024), with the movie marking his first time directing a Doraemon film. He commented:

10,928 meters—the deepest point ever reached by mankind. Let’s venture further with Doraemon and his friends! Certainly there are creatures and sceneries waiting for us that no one has ever seen. Aren’t you excited just thinking about it? The choices and decisions they face there may trouble them at times. But hidden among those will surely be ‘unexpected answers.’ To a deep-sea world no one has ever seen before—we look forward to the day we can experience it together on the screen.

The screenplay was written by Isao Murayama, making his first appearance in the film series. Since 2023, Murayama has written the scripts for several episodes of the Doraemon television anime series.
