Although retirement age is increasing in aging societies, its impact on individuals and communities is unclear. This study examined how age moderates the linkage between transition into retirement and participation in productive and non-productive social activities after retirement, using a nationwide longitudinal survey with a probability sample of Japanese aged 60 and over (n = 3,493). Multinomial logistic regression analyses were performed to predict changes in volunteering and hobbies/learning during 3-5 years of follow-up and their participation level at the follow-up. The significant interactions between change in work status (remained working as reference, full/partial retirement, remained not-working) and age at baseline showed that fully retired persons were more likely to increase these activities than remained workers only when they retired by their early seventies. Thus it is important to encourage engagement in social activities before retirement and remove psychological and environmental barriers that hinder starting new activities at old age.
