Which engine was used to develop Pokémon Pokopia?

Pokémon Pokopia was developed using the Katana Engine.

The Katana Engine is listed as the game's engine in its technical credits. A game engine supplies core technology for rendering graphics, handling environments, processing interactions, and supporting the systems that make gameplay possible.

Pokopia's engine supports a world built around construction and environmental change. Players collect materials, place furniture, create homes, shape habitats, and interact with Pokémon whose moves can affect the landscape. Those systems require the game to represent a responsive world rather than a sequence of fixed battle arenas.

The engine name is easy to confuse with well-known commercial engines such as Unity or Unreal Engine. Those are widely used across many games, but neither is listed as Pokopia's engine. Katana Engine is the specific name associated with this title in its game information.

Knowing the engine does not identify the developer. Game Freak and Omega Force developed Pokopia, while the Katana Engine refers to the technology used to build it.
