▲Large Banner Visual
In contrast to the main visual of Doraemon the Movie: New Nobita's Underwater Devil's Rock Castle, which depicts the underwater world, this image captures Doraemon and the gang on the beach, setting off on their adventure aboard the secret gadget, the Aqua Buggy. Various creatures are hidden within the large clouds, resulting in a playful visual that hints at the grand underwater adventure that is about to unfold. When you encounter the banner visual at the cinema, please enjoy trying to find the various creatures hiding within the clouds!
▲Large Standee Visual
The standee visual for Doraemon the Movie: New Nobita's Underwater Devil's Rock Castle is a special visual that allows you to take a photo as if you are riding the Aqua Buggy alongside Doraemon and the gang! Taking a picture with this large standee, which is over 2 meters tall and wide, is guaranteed to give you the realistic feeling of exploring the ocean floor!

Doraemon the Movie: New Nobita's Underwater Devil's Rock Castle
[Story]
It is the bottom of the sea, closest to the center of the Earth. An unknown world calling forth mysteries! A breathtaking, heart-stopping underwater grand adventure!!
Nobita and the others, whose opinions differed on where to go camping for summer vacation, decide to camp in the middle of the ocean following Doraemon's suggestion! The five friends enjoy underwater camping, encountering various creatures using the secret gadgets "Aqua Buggy" and the "Adaptation Light."
Their discovery of a sunken ship leads them to meet El, a mysterious young man. Surprisingly, he is an "Ocean Dweller" living in the vast Mu Federation beneath the sea! The Ocean Dwellers, who dislike surface dwellers, cannot trust Nobita and his friends. Amidst this tension, a report arrives: "The Devil's Rock Castle... has begun its activity!!" What exactly is the "Devil's Rock Castle" that the Ocean Dwellers fear...?
With hearts full of trust in their friends, they set off on a grand adventure for the fate of the Earth!
