This study attempted to explore how middle aged married men and women prospected a Centenarian society and what implications their prospect cast for family policy. We conducted focus group interviews with five groups in order to identify their subjective prospects on marital relations, parent-child relations, caregiving from family or institutions, and alternative living arrangement. From those interviews, we found that married men and women in their 40s, 50s, and 60s possessed ambivalent attitudes toward their marital relationship, either acknowledging an importance of marital relationship or accepting long-standing disrespectful marital relationship. They also had a dualistic perspective on parent-child relationship, accepting parental responsibility for children and even grand-children but maintaining low expectations for children. What they needed was age appropriate opportunities for work or leisure and better community services and facilities. These results showed that the middle-aged was concerned experiencing unprecedented family situations. They needed family life education and services in order to adapt to the Centenarian society. Since family policy has viewed this age group out of service target, programs and services have been underdeveloped for this group. Expecting a Centenarian society however, we need to expand the boundary of family policy and take a new perspective. We need to develop and implement marital education programs, community-based self-care services, and age-appropriated opportunities for work, leisure, and social relations.
