"In a society that employs a strong sense of ethnic and cultural unity, ethnic prejudice and discrimination typically prevent minority members from participating in main stream society. Both Japan and Korea are good examples of such a rigid society. Traditionally, the Korean government has been imposing various legal measures to prevent foreigners immigrating into Korea. However, Japanese minorities have been living in Korea, though small in number, for almost half a century. Most Japanese living in Korea today are elderly women with their Korean husbands, many of them now widowed."
