Cant really say. In HS I dated a half Japanese girl, her mom was Japanese, dad was American. So she was pretty much Americanized anyway. We were pretty tight, never had any issues. Until she decided she hated all my buds (story of my life) and gave me an ultimatum that I had to stop running with them. So it was sayonara. Too bad so sad.
OP…are talking about a women born in Japan and raised in the Japanese culture, or are you simply talking about a girl, or woman, that simply has Japanese ethnicity?
@Kropotkin It is an almost guaranteed, absolute certainty, that your days of carousing with your buds, shooting pool for money, and drinking beer, and sometimes fighting, are finis. As the French would say. But I’m pretty sure you already know that. : )
