Anuka is not really a Japanese name, in theory it could be and there might be a Japanese child called that way, but it's not really a well-known or frequently used name. Just from the sound it could very well be corean or chinese etc (if you say it was an asiatic child).
Same goes for Kitomi, in theory it would be possible, but there aren't many people called like that, at least nobody I can find :) To me it looks a bit like a misspelling of
Hitomi in fact.
Maybe you could tell me more about non-japanese children having japanese names? That would be very interesting, since I feel that Japanese names are extremely rarely used by non-Japanese parents.
