Looking by nationality, Chinese accounted for the largest number of foreign-born wives at 37.2%, or 5,526 marriages, followed by Filipinas at 22.7%, or 3,371 unions. Korean nationals were third at 13.6% (2,031), Thai fourth at 6.5% (970), and Americans rounded out the top five at 1.7% (246). While fewer Japanese men are taking brides from China and the Philippines, women from these and other nations in Asia still account for the majority of cross-country nuptials involving Japanese grooms, a trend that will likely continue.
