It's going to be very annoying to have to find some sort of cultural comparison for everything for everything in RWBY. Otherwise we'd have to explain that "Yang" means sun in Chinese despite Chinese not existing as a language in the RWBYverse. Or what the a Yatsuhashi is in not-Japanese. I don't think they even have an Asia or Europe, but then things would get really confusing. Then again (using Yang again) I don't know a lot of tall blond and busty Chinese women in real life.
