I've always had a huge things for Japanese girls the the “gravure idols" who do everything in photos except take their clothes off.
There's a good guide here :
AskMen.com - Top 10: Japanese Models that should set the pulse racing.. But personally you can't beat a bit ( well a whole lot of ) Miri Hanai , Yoko Matsugane & the top of my list Harumi Nemoto.
The very good news is the GF also has a thing for Japanese girls and we are off to Tokyo early in the new year :)
