Abstract
The results of variance analysis show that the birth order is significantly associated with the willingness to live together; that is the first or the only son tends to say that he would like to live with his parents immediately after marriage. A sense of first son's responsibility to continue the family lineage seems to be quite strong in all three countries.
Though attitudes towards shared living arrangements seem to have been influenced by the traditional norms of the patrilineal stem family system, attitudes toward financial and physical supports are related to personal experiences. Those who were satisfied with their family life showed more willingness to support their parents financially or physically if they became dependent. Those who had often been told to provide filial piety in their childhood tends ended to show willingness to care for the parents when they become bedridden.
