Where did humanity relocate from Pokémon Pokopia’s world?

In Pokémon Pokopia, humanity relocated to outer space after the planet became inhospitable.

The game’s story presents a world that humans could no longer safely inhabit because of unexplained environmental phenomena. Rather than remaining on the damaged planet, humanity departed for outer space. This explains why Ditto encounters abandoned places and why Pokémon habitats require extensive restoration.

The evacuation also creates the game’s central mystery. Humans did not simply vanish without leaving traces: logs and technological systems remain behind, allowing Ditto and Professor Tangrowth to piece together what happened. The story therefore connects environmental decline, human migration, and the long-term survival of Pokémon.

Outer space is broader than a named destination such as the Moon or another planet. The available story description identifies humanity’s relocation as outer space, not a specific celestial settlement. That wording is important because it avoids inventing a destination the game does not identify.
