What is Pokémon Pokopia’s main setting described as?

Pokémon Pokopia is set in a post-apocalyptic world.

The game begins after humans have disappeared from the Kanto region, leaving the environment damaged and difficult for Pokémon to inhabit. Ditto becomes the central helper, using a human-like form and learned Pokémon moves to restore habitats, grow vegetation, and make the landscape livable again.

The post-apocalyptic setting is presented through exploration and story discoveries rather than through a violent survival-horror tone. Players gather materials, build structures, create homes, and attract Pokémon by designing suitable habitats. This contrast gives the game its distinctive combination of a mysterious past and a gentle, constructive present.

The setting is sometimes mistaken for a simple empty wilderness or an entirely new fantasy world. It is specifically a future or altered version of Kanto after a major collapse. Story logs explain that humanity eventually left Earth for outer space, while Pokémon were stored in a massive computer system intended to preserve them.
