Nobita finally gets to be right about something, and the movie lets him stay right even when nobody believes him. The bunny colony he builds becomes real proof, not just his usual tall tale nobody wants to hear. By the time mysterious kids show up who know exactly what he's talking about, you realize the show spent decades earning the moment when Nobita's imagination stops being a joke and becomes the world.
When a Japanese lunar probe detects something impossible on the moon's far side, Nobita watches in real-time as the entire surface shifts to an eerie yellow. Desperate to uncover the truth, he drags Doraemon into another time-bending adventure, and together they establish an unlikely settlement populated by genetically engineered moon rabbits. What begins as a simple expedition becomes something far stranger when Nobita returns home with an incredible story no one at school will accept. Then two mysterious transfer students arrive, siblings whose origins and knowledge seem to come from somewhere impossibly distant. Their arrival forces Nobita to confront the possibility that his lunar adventure was far more significant than he realized, and that the moon holds secrets that might reshape everything he understands about Earth's place in the universe. This film blends Doraemon's signature blend of invention-powered comedy with genuine cosmic mystery, creating a narrative that respects longtime fans while remaining accessible to newcomers discovering the franchise.
