it's not a bad thing as long as you're not putting down women of other races, which is what losers afflicted with yellow fever generally do... which is partly why they have such a bad rap.

also, they're women like any other in the world. it's been said a billion times, but as a chick who dates chicks and who has tons of chick friends, i'll say it again. across cultures and ethnicities, we all tend to have the same problems and characteristics. we're varied because we're indivudals, not because of our skin colour. whatever personality traits/characteristics you like about japanese women, you can probably find them among your own race too, so there's no point in limiting your search.
