Kalos is the Pokémon region heavily inspired by Metropolitan France.
Kalos is the setting of Pokémon X and Y, and its star-like shape and landmarks draw on French geography and culture. Lumiose City, the region’s major metropolis, is strongly associated with Paris and features Prism Tower, an obvious counterpart to the Eiffel Tower.
Other locations reflect French architecture, landscapes, and historical sites. The region’s emphasis on beauty also matches the games’ themes and their focus on visual presentation, character customization, and the Fairy type.
Kalos is not the only Pokémon region based outside Japan. Unova draws heavily from New York City, Galar from the United Kingdom, and Paldea from the Iberian Peninsula. These inspirations are fictionalized rather than exact maps, so a region may combine references from an entire country or broader area rather than reproduce one real location precisely.
