Doraemon Movie 10: Nobita no Nippon Tanjou

Tired of life at home, Nobita decides to run away, only to discover that every convenient piece of land already belongs to someone. When his friends develop similar frustrations, Doraemon offers an impossible solution: travel tens of thousands of years into the past, before modern ownership existed, and build a place of their own.

In prehistoric Japan they meet Kukuru, a boy whose tribe has been captured by the mysterious Giga-Zombie. What began as an escape from ordinary problems becomes a rescue across an ancient wilderness, as Nobita and his friends use Doraemon's tools to protect their new companion and confront an enemy manipulating the distant past.
