This isn't a personals site. If you are looking to meet girls in Japan, I'd suggest Metropolis Classifieds or maybe JapanCupid.
I've had a lot of experience with Metropolis Classifieds. Basically, it's a great way to meet new people. A lot of the women have been played too much by men and tend to be very strict about what they are looking for. Be sure you include a picture and you should also request one a well. I have yet to meet a woman on there that just wanted to play, though. Good luck!
