Which company’s Omega Force studio helped develop Pokémon Pokopia?

Koei Tecmo’s Omega Force studio helped develop Pokémon Pokopia.

The game credits Omega Force as a co-developer alongside Game Freak. Omega Force is a studio within Koei Tecmo, so Koei Tecmo is the parent company requested by this question.

This collaboration was chosen partly because Game Freak wanted additional expertise in sandbox game development. Omega Force had worked on titles such as Dragon Quest Builders 2, making it a natural partner for a Pokémon game built around construction, environmental change, and habitat creation.

The wording matters because Nintendo and The Pokémon Company are publishers, while Game Freak and Omega Force are developers. Koei Tecmo is not the game's worldwide publisher; it is the company behind one of its credited development studios.
