>>52721320>why the fuck did they give it a japanese name that isn't its japanese name?Tatsugiri is easier to pronounce and is still obviously Japanese (as intended/appropriate for a sushi Pokémon)
Aside from most Legendaries since Gen 2, most Pokémon don't retain their original/Japanese name in other languages. They get localized with a similar name following the same theme based on the Japanese or English name (or they just copy it outright if they're feeling lazy, or the English name is already a pun in their language).
A lot of the Paldean Pokémon with Spanish-sounding names, like the starters, also have Spanish puns in their Japanese names.
