Japan: Social Customs The information provided, talks about family traditions, marriage customs, and education in Japan. I think the way marriages are setup in Japan are much different than thus of the United States. Family roles are also very different. In Japan, it is common for newly wed couples to live by themselves until their parents get old. Many couples intend to live with their parents only after spending years all by themselves. However, if the husband is not in a position to support his parents, which means most of the time that he is not the first child of the parents, they don’t plan to live with them. With this tendency, the housing industry is prosperous.
