Japanese Study of Aging and Retirement
JSTAR project researchers aimed to construct a world-class longitudinal dataset on middle-aged and elderly Japanese persons to enable researchers worldwide to perform scientific investigation on aging and retirement from an international perspective.
This study aims to describe in detail how middle-aged and elderly Japanese live in terms of economic, social, health, and family status. In this project, the intention is to zoom in to paint a picture of the lives of individuals and zoom out to also provide a panorama view of society, while extracting scientific findings which we hope are innovative and insightful regarding life in Japan as well as other countries in the world. Moreover, it tries to connect these new scientific findings to efforts toward enhancing the effectiveness of policymaking.
