Which Pokémon spin-off game engine powers Pokémon Pokopia?

Pokémon Pokopia is powered by the Katana Engine.

The Katana Engine is listed as the game’s engine in its technical information. An engine supplies the underlying technology used to render graphics, process gameplay systems, and support the interactive world. For Pokopia, those systems support a world that can be cultivated through construction, environmental changes, and Pokémon habitats.

Engine information is separate from the game’s genre, developer, and platform. Pokopia is a social-simulation game, was co-developed by Game Freak and Omega Force, and released for Nintendo Switch 2. Those facts describe different parts of the title’s identity and should not be substituted for its engine.

The name may be overlooked because promotional coverage tends to emphasize Ditto, building, and the game’s post-apocalyptic Kanto setting. Nevertheless, Katana Engine is the specific technical answer recorded for Pokopia. It is also distinct from commonly cited third-party engines such as Unity, Unreal Engine, or Frostbite.
