How many people have you introduced to thought Ayumi was white?

[Weslicious]

I can see how now people may get confused just by looking at more recent pictures. Just looking at the sigs and such in this thread (Chibi Venus, extepan and Hybrid Theory) you wouldn't instantly jump to her being Japanese/Asian. She was typically Japanese looking in the early days though so no confusion there.
Are you introducing her right though? This is Ayumi Hamasaki, a J-Pop star? Not much room for people to not know she's Japanese there.
