I am absolutely crazy about Japanese girls, but Japanese hardcore porn doesn't appeal to me at all. I am so used to shaved/trimmed pubes, that the super-hairy overgrown bushes of Japanese AV stars (pixelized or otherwise) are really revolting to me. Also Japanese guys just don't seem to cut it for me as performers. But I love Japanese gravure - the costumes, production values etc are amazing.
Right now I am crazy about a girl called Toshimi Horiguchi whose work fits into a genre called Chaku-ero:

So it's non-nude, but pushing the boundaries. She has an amazing ass and wears lovely lingerie. I found torrents of her DVDs and some of them are super-hot - even though you never actually see her pussy, they're actually much more of a turn-on than any number of generic US hardcore films. Here is that ass:
You can find a torrent of her latest DVD double-release here - it is awesome:
