Nippon.com and the Japan Ministry of Health, Labour, and Welfare report, in 2013 there were 21,488 international marriages in Japan (1 in 30 of all marriages). Of those, 6,046 were between Japanese women and foreign men, and of these, 19.2%, or about 1,161, involved American men marrying Japanese women.
On the other side, 15,442 marriages involved Japanese men, out of which 1.2%, or about 185, involved an American wife.
So in Japan, marriages between American men and Japanese women outweigh those between Japanese men and American women by a rate of 600%.
