Pocopoké is Pokémon Pokopia’s Japanese short title.
The game’s Japanese title is written as ぽこ あ ポケモン, while Pocopoké, written ぽこポケ, is used as a shorter form. The abbreviated name preserves the playful sound of the full Japanese title while making it easier to use in informal references.
International audiences may encounter several romanizations when Japanese Pokémon titles are discussed. That can make the short title look like an unrelated product, but it refers to the same game announced and released for Nintendo Switch 2.
The English title Pokémon Pokopia is the name used for the international release. Pocopoké is not a second game, a character, or downloadable content; it is the Japanese short form connected with the title’s original naming.
