Abstract
Housebound status among the elderly is linked to frailty and health issues, with confinement rates higher in local areas (15%) compared to urban areas (7%). This study explores the impact of the transportation environment on elderly mobility, focusing on those aged 65 or older in Setagaya Ward, an urban area with well-developed transportation infrastructure. The survey targeted individuals who went outside at least two days a week and participated in volunteer activities. Results showed that 73% of those in the pre-housebound group (going out 2-3 days weekly) did so for volunteer purposes. This suggests that social engagement through volunteering encourages elderly mobility. Additionally, the absence of mobility difficulties appears to be more critical than motivation alone in facilitating volunteer participation among the elderly.
