Abstract
A survey by questionnaire was conducted to study the frequency and range of movement of residents in Niyodogawa-cho, Kochi Prefecture, located in a mountainous region. The result is classified by age group. It is confirmed that the frequency and the range of activities differ by age group: the higher the age, the lower the frequency. It is predicted from the results that the situation rapidly changes in a rapidly aging mountainous region. This prediction is required to be considered for planning of development and maintenance of infrastructure.
