True! When I took Japanese in college, my instructor, a Japanese woman married to an American man, told the class, "If you ever go to Japan, don't fall for a Japanese man!"
Wasureruna!
Actually, my blond-haired, blue-eyed Sister-in-law went to Japan for her junior year of college, she was majoring in Japanese. Met an English/teacher Japanese grad student, fell in love, got married. That was 15 years ago. Now has four amerasian babies and lives on her in-laws tea and mushroom farm in southern Japan.
She has told me, though, that there is a prejudice shown toward the children, being of mixed race is not all that accepted in Japan.
But, there are some Japanese men who will go for the exotic blond american women.
