Are you comfortable with a Japanese-American woman? If so then you'd at least have more options.
Also, why only Japanese? I know you respect the culture and all, but when it comes to
it's best to let it come to you. I'm no love guru, but I at least know that it's a plant of slow growth; best to start off from acquaintances, then become friends, then friends with benefits, then gf/bf, then you'll know when to let the seriousness set in. Also, I myself love a lot of Japanese guys and girls. But I've liked a lot of Chinese and Korean as well. My best suggestion would be to actually go to Japan and mingle around while you're with your friends. That's the old-fashioned way of meeting them and it's the best.
