Namie Amuro is pretty.

She's so sweet when she smiles and I love her hair. She also looks so natural to me somehow. Not just a doll like (sorry guys) Ayu sometimes, but yeah.
Other natural beauty is Utada Hikaru. She looks very pretty and I loved that ULTRA BLUE cover. That's pretty.
I like it when artists look natural and doesn't use lots of make up. :> I really don't think Namie uses that so much like Kuu and Ayu imo. But I don't say Kuu and Ayu are ugly. I think they are pretty too, but I really like natural beauty which Namie and Hikki has.
Yet my vote goes for Namie, because she looks like she's younger than she really is which caught my attention in the first place. :p
