Across Japan, the rapidly aging population is becoming more visible, especially in “aging new towns”. Since mobility levels usually decline with age, having a self-contained neighborhood could be more important than before. This paper therefore explores the self-containment status of a new town for discretionary activities (shopping, volunteering, recreation, and so on), by using multiperiod (two waves) and multiday (two weeks) panel survey data collected in Koyo New Town located in Hiroshima, Japan. For this purpose, we develop a panel mixed logit model of destination choice with a focus on the impacts of social networks. We also examine whether or not the self-containment contributes to the improvement of residents' subjective well-being. The result reveals that social networks have a positive impact, not only on self-containment of discretionary activities, but also on residents' subjective well-being.
