When I was hanging out in bars there, young women would approach me and beg: "Teach me Englishu!" They saw that I was white and foreign and figured I could just pour English fluency into their heads.
As for the personal questions -- yeah, I've undergone enough foreign-language instruction to understand that these are things people resort to just to have something to talk about. One question that kept coming up was "Who is your favorite singer?" Just about everyone who asked me this also provided their own answer to the question and it was always the same -- Lady Gaga. (The album Born This Way had just dropped in Japan at the time and Lady Gaga was all the rage -- bigger than One Piece, even.)
