Asian migrant brides in Japan
The increasing number of Asian migrant brides in Japan marrying Japanese men is a phenomenon occurring in both rural and urban Japan. Since the mid 1980s, rural Japanese men have begun taking foreign Asian brides, from the Philippines, Sri Lanka, Thailand, China and South Korea, as a way of compensating for the reduced number of Japanese women of marriageable, childbearing age who are willing to marry rural Japanese men.
