Well SEAs have pale skin so I think we can write that off. As for the big eyes thing, maybe, that's certainly the caucasian impression of caucasians. I mean we don't actually have bigger eyes, the difference is in the skin near the corners of the eyes so maybe the perception of westerners having big eyes isn't actually held by native japanese. I don't know though, maybe that impression is universal. I do find the portrayal of non-japanese characters in anime to be interesting. It seems to vary widely. I watched an anime series recently where the only noticeable difference between westerners (English, specifically) and Japanese was that every western character had a sharp outer corner of the eye which seemed to imply a sense of intensity more than any physiological difference. I always found Code Geass to be kinda funny because the main English character looked way more Japanese than the main Japanese character, and in general Japanese characters were more likely to have western phenotypes than characters who were supposed to be genetically western.
