"Doraemon the Movie: Nobita and the New Castle of the Undersea Devil"
QuizKnock's Mon Higashi and Gen Higashi Brothers Appointed as Promotional Ambassadors!
The twin quiz players Mon Higashi and Gen Higashi, members of the intellectual entertainment group QuizKnock, have been appointed as promotional ambassadors for "Doraemon the Movie: Nobita and the New Castle of the Undersea Devil"! Comments have arrived from the two, known as brothers who love Doraemon dearly.
Comment from Mon Higashi
Since my name contains "mon," I've loved Doraemon since I was young. Every Friday night was spent waiting in front of the TV for the anime to start. I watched every installment of "Doraemon the Movie" through rental videos my parents borrowed for me, and come to think of it, I believe the first quiz book I ever read thoroughly in my life was "Doraemon the Movie Quiz Encyclopedia."
Even now, I still go to theaters every spring to watch the new films, and it's become a tradition to speculate after seeing the post-credits scene, saying things like "Next time, the setting will be such-and-such place." If I told myself from a year ago, when we were discussing "Nobita's Story of the Picture World," that "next year you'll be involved with the movie in this way," he might not believe it so easily, just like Nobita's grandmother.
When doing quizzes, you end up with many things and places you know about but have never seen or visited, and each time my curiosity cries out "Doraemon!" for help. This film, where Doraemon takes us like that into the sea, is a wonderful work packed with both "So this is what it's like as an adult!" and "So this is what it's like as a child!" Let's enjoy it together!
Comment from Gen Higashi
I've been familiar with Doraemon since I was small. Reading the manga, watching the TV anime... Also, Doraemon was part of our annual traditions. In September, we watch the moon, and we also watch Doraemon's birthday special. In December, there's Christmas, and there's also Doraemon's New Year's Eve special. And in spring, there's the Doraemon movie! I've been appointed as a promotional ambassador for such a movie. I feel emotion, gratitude, and above all, surprise. I've watched all the Doraemon the Movie films. Being able to see the latest work before everyone else, I feel both joy as a fan and also a bit sorry. Sorry everyone!
This film is a remake of "Nobita and the Castle of the Undersea Devil" released in 1983. Of course, I've seen the 1983 film as well, but even knowing the story, it's still interesting. The beautiful underwater world and the thrilling action. Furthermore, this time there will be the series' first 4D screening. I'm also looking forward to seeing it in theaters. Let's set off on an adventure to the evolved undersea world together with Doraemon and friends!

Scene Cuts Foreshadowing a Great Undersea Adventure Released All at Once!
Doraemon and friends leap out of their everyday lives and head into a magnificent undersea world no one has ever seen. Packed with exciting cuts, from Nobita and friends riding "Underwater Buggies" into the depths, to peaceful moments chatting inside the Gadgets "Tent Apartment," and even the surprising sight of a giant squid approaching!!! Cuts have also arrived showing magnificent mountains spreading across the seafloor and the Mu Federation, the nation of undersea people, visible in panoramic view. Expectations are building for the beautiful undersea world!
Also captured are Doraemon and friends rising up with El, a soldier of the Mu Federation, to fight for the fate of the Earth. The full view of "Onigashima Castle" feared by the undersea people, the figures of the "Iron Cavalry Squad" standing before Doraemon and friends, and the form of "Poseidon" who rules Onigashima Castle have all been revealed!! An ominous atmosphere pervades. Please look forward to the unpredictable developments awaiting Doraemon and friends!
