Pokémon Pokopia lists support for nine languages.
The supported-language list includes English, French, Italian, German, Spanish, Korean, Simplified Chinese, Traditional Chinese, and Japanese. Counting those entries gives a total of nine.
Simplified Chinese and Traditional Chinese are listed separately, so treating them as one language would produce an incorrect total. The list also distinguishes the language options from the game’s supported play modes, which include TV, tabletop, and handheld modes. Language support is a product feature and does not indicate that every region received identical publishing arrangements.
