Which development studio partnered with Game Freak on Pokémon Pokopia?

Omega Force partnered with Game Freak on Pokémon Pokopia.

Omega Force is a development team within Koei Tecmo, and it co-developed Pokopia with Game Freak. The partnership brought together Game Freak’s Pokémon expertise and Omega Force’s experience with sandbox-style games.

The collaboration was particularly associated with Dragon Quest Builders 2, which helped demonstrate Omega Force’s familiarity with building-focused gameplay. Pokopia uses similar broad ideas—collecting materials, constructing spaces, and shaping a world—but places them inside a Pokémon life-simulation setting.

Game Freak remained one of the game’s principal developers, while Nintendo and The Pokémon Company published it in different markets. The project therefore combines several major companies while keeping its focus on a distinctive Pokémon spin-off.
