What would the job be called? She wants to create the visuals of a Pokemon, which can then be transferred into sprite form by someone else.

5087400 can she speak/write Japanese?

5087524 She knows rudimentary, a tiny bit of Japanese

5087576 well unless she can speak like natives/ or like people who lived in Japan since 6~10 years old it can be hard to find jobs in Japan... not to mention some companies are bit wary of foreigners...

5088253 Maybe in any American branches, if there are any

5088726 I don't think American Pokemon companies have any real input in creating Pokemon- I know some Westerners have given some chance in creating Pokemon ( like James Turner) but chances are few in between and mostly western Pokemon companies are more focused in localizing pokemon.

5088815 Ah, OK then.
