From the deep, hidden from the joy of a full days-worth of sunshine in these winter months valleys of Nagano...WELCOME to Jref !! I sometimes wish, I could know more about any girl from that area too...hee, hee, hee...
But seriously, I am sorry, I cannot really help other than to say, that I would see very little reason to think the women there are that much different from the women of any fairly nearby areas of Japan, or even the farther away areas of Japan.
Cue's question is correct, however, a person would surely need to know more about the theme that the paper will carry, and the type of thesis you are trying to develop.
I hope to see you 'round more and more..busy with papers or not ! MM
