and grossed over 1.89 billion yen! ※Data from Kogyo Tsushinsha for 3/13~3/15
Scroll down into a mysterious underwater world!
"Three consecutive underwater exploration visuals" with expressions that change by layer have been released!



The visuals released this time are three new types that express the depth of the sea, which is the stage of the adventure!
The first picture depicts Doraemon and the others playing with sea creatures in the beautiful sea where light shines through. It's a vivid, sparkling underwater world that heightens expectations for the great unknown adventure about to begin.
The second picture shows a complete change in atmosphere as we dive deeper. It depicts a mysterious and dangerous海底 with a sunken ship and giant squid tentacles sneaking around, with El desperately trying to tell them something. It suggests the danger approaching Doraemon and the others.
The third picture, at the deepest part, shows a world where light doesn't reach. In the background stands Oni-Iwajō, which the underwater people fear. It captures a tense scene where Doraemon and the others struggle with their water buggies to escape the pursuing iron cavalry.
When you arrange these three pictures vertically, they form one large picture! It's an immersive visual that lets you experience the scale of the story all at once, from the sunlit surface to the mysterious depths!

Director Tetsuo Yajima, who has been involved in numerous masterpieces such as "Nobita's New Great Adventure into the Underworld: The Seven Magic Users (2007)", "Nobita and the Steel Troops: Winged Angels (2011)", and "Nobita's Earth Symphony (2024)", makes his directorial debut in the series with "New Nobita and the Castle of the Undersea Devil".
In the first post on March 16, Director Yajima will reveal a scene close to his heart!
Regarding the opening scene where Nobita does homework with the support of Doraemon, Shizuka, Big G, and Suneo, the director says, "It's an important scene that well represents the relationship between the four, so we carefully crafted the atmosphere and colors." The scene conveys the warm friendship of Doraemon and the others through their casual everyday interactions, wrapping the viewer's heart in warmth.

Breathtakingly beautiful, underwater world art boards are all revealed!
"New Nobita and the Castle of the Undersea Devil" has meticulous attention to color settings and art as well!





The released art boards depict everything from the beautiful sea world where fresh water patterns are reflected on the sandy beach, the fantastic streets of the underwater nation "Mu Federation," a campfire underwater, and the full appearance of "Oni-Iwajō" and the artificial intelligence "Poseidon" that the underwater people fear. The unknown world depicted in high resolution is truly immersive!
