well, jap girls generally think very poorly of customers I guess. in my entire punting history, I recall only one jap girl who had a genuine interest in talking to me, she was very nice looking and elegant, with a kind heart and good personality. during the last session she tearfully told me she was going back to Japan, talked a lot about her past, and gave me a big hug before saying bye.
I'll forever remember this girl from ikebukuro.
But this is absolutely the exception rather than the rule.
