Intergenerational Coresidence of Older Adults in Japan: Conditions for Cultural Plasticity

This study investigated individual-level conditions and prefecture-level contextual factors that enable and/or restrict intergenerational coresidence arrangements between older parents and adult children. Whereas the traditional pattern of coresidence was primarily a value-driven arrangement, nontraditional coresidence was both a value-driven and a need-driven arrangement for older parents with limited physical abilities. The differences between the two types of coresidence are consistent with a shift of intergenerational living arrangements in Japan from a preventive arrangement to a contingent arrangement for older parents in need.
