Which company developed Pokémon Pokopia alongside Omega Force?

Game Freak developed Pokémon Pokopia alongside Omega Force.

Game Freak is the studio best known for creating and developing the core Pokémon video games. For Pokopia, it worked with Koei Tecmo’s Omega Force, bringing together Pokémon expertise and experience with building-focused games. This partnership helped shape Pokopia as a social simulation and sandbox title rather than a traditional battle-centered adventure.

The collaboration is notable because Omega Force is associated with Koei Tecmo, while Game Freak is closely identified with Pokémon’s main series. Nintendo and The Pokémon Company published the game, but neither is the developer named in this answer. That distinction is a common source of confusion when several companies appear in a game’s credits.

Pokémon Pokopia was designed around crafting, construction, habitat creation, and friendship with Pokémon. Its development team therefore combined the Pokémon world and characters with systems suited to a slower, creative style of play.
