Please. She’s still a minor.
So are all the half-naked cheerleaders at your local high school. So what? The good-natured, harmless appreciation of older teenage girls is as American as apple pie.
Miss Shinozaki a legal adult in Japan now, and her eighteenth birthday is on 26 February, 2010. (NB: The age of consent in Japan is 13.) While I'm old enough to be her dad (and happily married besides), I think it's ridiculous to pretend that something magical happens to young women at the stroke of midnight on the day they turn 18 that changes them from innocent children to reproductively-ready adults.
I don't advocate the romantic pursuit of such young beauties by men outside of their age cohort — only a cad would do such a thing. (Did we learn nothing from Gigi?) However, I think that it's prudish and hypocritical to pretend that girls like Miss Shinozaki aren't charming and pleasant to behold.
My late, beloved grandmother was married at age 14. My own mother, God bless her, married at age 16. While getting married at such a young age isn't advisable for a variety of reasons, biology isn't among them.
