She's an actress who seems to be not that unknown, if you look around you'll find a lot of news articles. I found her through the pinku eiga "The Perfect Education" (Kanzen naru shiiku) from 1999, a sleazy male fantasy where a guy captures a girl not in order to rape her, but to make her the perfect lover.
She's 41 now, but she did a nude photo collection when she was much younger. I have to look around for some other pinku movies with her that are available, I really liked her performance in spite of the cheap story!
She's appearing in much more mainstream movies now, just as she had before she went to do pinku.
Anyway, let's get to the nudes.
