Ummm, why should I? There's a bunch of perfectly good names in this thread already.
And, like I said, there's no real ethnicity in KH save for Chinese, and that's for a single world. And, as I mentioned before, characters in Japanese games and anime hardly ever look Japanese. Including some of the Japanese ones (Because, to be honest, it's hard to find a Japanese guy with bright orange hair [liek omg bleach reference!!1!]).
So, technically, any sort of last name could probably work. But personally, I'd go with Japanese to, you know, match their first names (which are also OMG! Japanese, even if they've been converted to romaji)
