In this paper, we discuss the relationship between elderly people's activities and their neighborhood environment. We took four residential districts in Kumamoto city as the case ; two districts represent active districts in terms of the going-out activities of the elderly, while the other two represent relatively inactive districts. In these districts, we analyzed 628 sets of answers of the elderly people to the questionnaire, and investigated both physical and social conditions of their living environment using fieldwork data and statistical data. We analyzed in the questionnaire, the activity preference of the elderly in the daily life, destinations of their going-out activity, their evaluation of the neighborhood, and then, the relations between their going-out activities and the physical condition of each district. Findings are summarized as follows : 1) There are no differences in the activity preference of the elderly between the active districts and the inactive districts. 2) In the active districts, the elderly people's territories of daily life are formed densely in a relatively smaller area, while those in the inactive districts are extended sparsely. 3) In the active districts, several places that elderly people freely access through safety pedestrian network can be found within the walking distance. 4) In the active districts, the elderly highly evaluated the existence of comfortable environment of walking and convenient shopping facilities in each district. But even in the case that the district has only poor commercial service, they evaluated their neighborhood well if onlv they have comfortable walking environment and intimate relationship with neighbors.
