First, BoA is NOT Japanese. But truly beautiful.
Second, I voted for others. I'm not biased but I truly think Ayu is simply gorgeous. She has really beautiful delicate facial features. No, I'm not talking about the eyes only. She doesn't look like any other Japanese artists.
I also think hitomi is simply fantastic. Her face is so special. <3
And of course, MIKI FUJIMOTO! So beautiful.
Namie is also really pretty. But she's nothing quite special.
