What is Pokémon Pokopia’s main setting described as after humans disappear?

Pokémon Pokopia is set in a post-apocalyptic world after human society has disappeared.

The setting gives the game’s gentle construction activities a larger purpose. The player-controlled Ditto explores a damaged environment, meets Pokémon, gathers materials, and helps cultivate habitats where communities can develop. Instead of presenting the apocalypse mainly as a combat threat, Pokopia uses it as the backdrop for restoration and rebuilding.

The premise can be confused with a conventional Pokémon region because the game still contains familiar creatures, exploration, and environmental areas. However, it is not described as a futuristic city, tropical resort, or medieval kingdom. The absence of humans is particularly important: Ditto imitates a human while helping restore the world and assist the Pokémon it encounters. This unusual combination of ruined surroundings and cozy life-simulation mechanics is one of the title’s defining narrative features.
