The present study examined relationships between the levels of leisure-time, household, and occupational physical activity (PA) with psychological status and social networks in older Japanese adults. Of 2,100 adults aged 65 to 85 years randomly drawn from the resident register in Kasama City, 349 completed a required questionnaire. We assessed their PA using the Physical Activity Scale for the Elderly. A partial correlation analysis and analysis of covariance (ANCOVA) were performed to evaluate relationships between participants’ three types of PA and scores of the Geriatric Depression Scale (GDS) and Lubben Social Network Scale (LSNS). We adjusted for age, educational level, and annual equivalent income. In men, higher leisure-time PA associated with favorable scores of several factors in the GDS (r = -.27~-.30) and LSNS (r = .17~.27). In women, higher leisure-time PA associated with favorable scores of GDS energy loss scores (r = -.15) and LSNS friends networks (r = .21). Older men with higher household PA displayed favorable scores of the GDS energy loss (r = -.19) and several factors in the LSNS (r = .18~.25). Older women with higher household PA displayed favorable scores of several factors in the GDS (r = -.18~-.25) and LSNS (r = .21~.22). The ANCOVA indicated that the level of leisure-time PA was lower in women living with both husband and relatives than in those living with relatives and no husband. The level of household PA was lower in men living with both wife and relatives than for men living with relatives and no wife. Psychological energy may be necessary to increase leisure-time PA and household PA in both older men and women. Leisure-time and household PA were more related to social networks in men than women.
