A little summary of my favorites:
Hitomi Tanaka -- lovely girl, spectacular breasts, seemingly willing to do almost anything erotic on film with great enthusiasm and charm.
Well, I guess she doesn't do anal, but that's certainly forgivable in light of the things she IS willing to do. Tremendously prolific, she has done videos with amazing variety, appealing to many different fantasies. Clearly the reigning queen of Japanese porn performers.
Fuko -- her adorable grin and gorgeous, huge bust had her as my favorite Japanese model for a long time. The most outrageous tit-to-body-size proportion I have ever seen. She was absolutely charming doing gravure, but never seemed at ease doing porn, and seems to have disappeared completely. I miss her.
Maria Yumeno -- mature and wonderfully sensual porn star who had her breasts augmented fairly late in her career. Played roles as a hungry and grateful middle-aged woman, marvelously erotic. This woman has an incomparable skill to tease and titillate a man. Her work seems to be relatively rare compared with the two above.
Rui Akikawa -- great, exotic looking girl with beautiful darkish skin and perfect large breasts. Comes across as mischievous, naughty and uninhibited. Again, not enough of her work available in the US.
Rin Kajika -- The newest of this bunch, I think; she's done some hardcore but doesn't seem as comfortable at it as Hitomi or Rui. Beautiful tan skin, gorgeous big breasts.
Kaori -- Young, with amazingly large and shapely breasts, but keeps her face hidden and has mostly done softcore videos with some guy licking and sucking her lovely tits. I'd sure like to see the rest of her.
All of these girls are exceptional for having slender bodies and sensational breasts. I would be happy to see more of any of them.
