Doraemon: Nobita no Nippon Tanjou

As Doraemon, Nobita, Shizuka, Jyaian, and Suneo decide to run away from their homes, they flee towards 70,000 years back in time. After a brief exploration of prehistoric Japan, they end up meeting Kururu, a boy from the primitive era. To help him reunite with his tribe, Doraemon and the gang will need to fight a shaman from another tribe who has captured Kururu’s kin to work as slaves.

Nobita wants to run away from home, again. He finds out that there is nowhere for him to go. All the land is owned by someone. His friends end up wanting to run away also, even Doraemon. They figure out that the only way to find land that isn’t owned by anyone is to go back in time to when no humans existed. They end up helping a prehistoric boy rescue his tribe from Gigazombie.

When a variety of circumstances leave Nobita, Doraemon and the gang wanting to run away from home, they face the task of finding somewhere to live. However, with every seemingly spare piece of land already owned by someone else, building themselves a house looks impossible – that is, until Nobita has the idea of travelling back seventy thousand years into the past. While the group are making themselves at home in an uninhabited Japan, back at home a glitch in space-time has sent a caveboy crashing into the middle of the city. When they return to the present, Doraemon et al encounter the child – named Kukuru – and take him with them back to their prehistoric paradise. Together, the gang decides to return the young boy to his true time and help him free his captured friends, even if it means facing the dangers of Kukuru’s enemies: the dark tribe.
