With some series', I think that's it. Fruits Basket, Tactics, Sailor Moon.... I have a working knowledge of Japanese culture, but not to the point where I can write consistently and not have to look things up. Or ask nekokoban.

But animes that are based in fantasy or European cultures (Lodoss War, Star Ocean, FMA) it's not so much the culture as (and the poster before you hit it on the head) the translation of the media. Anime relies so heavily on visual cues that it's difficult to transition that to writing. My powers of description leave something to be desired as is, let alone trying to write anime descriptions.
