Doraemon the Movie: Nobita's Sky Utopia

Nobita (Megumi Oohara) is a schoolboy who is bad at nearly everything and has a robot cat from the future, Doraemon (Wasabi Mizuta), living in his closet. When they hear of Utopia, a perfect land in the sky where everyone is happy, they set out in an airship with a time warp function. Takumi Doyama sends Nobita, Shizuka, Gian and Suneo up with them, five friends and one small round robot rising above the clouds.
