Who conceived Pokémon Pokopia as a spin-off focused on Pokémon habitats?

Shigeru Ohmori conceived Pokémon Pokopia as a spin-off focused on Pokémon habitats.

Ohmori, a Game Freak developer and director of Pokémon Scarlet and Violet, began considering new directions for the franchise during that game’s development. His idea centred on letting players create and cultivate habitats for Pokémon.

The concept drew on Ohmori’s earlier experience as a map designer on Pokémon Ruby and Sapphire. Instead of treating the map merely as a route between battles, he imagined giving players greater control over how Pokémon environments were shaped.

Ohmori was the concept and senior director of Pokopia, while Omega Force’s Takuto Edagawa served as chief director. Their roles are related but not identical, which is why the answer is Ohmori rather than Edagawa.
