Doraemon: Nobita and the Birth of Japan

Nobita feels like running away from home yet again, but he realizes there’s no place left unclaimed-every piece of land already belongs to someone. Soon, his friends join him in wanting to escape, even Doraemon. They decide the only solution is to travel back in time, to an era before humans existed, where no one owns anything. Along the way, they help a young prehistoric boy save his tribe from a creature called Gigazombie.
