抄録

The purpose of this paper is to clarify the situation of aging of infrastructure in Japan using the ratio of net capital stock to gross capital stock, and to reveal the problems about the maintenance of infrastructure based on the infrastructure asset management system, which is introduced in the local government of Japan in recent years. With respect to the aging of infrastructure, we fi nd that the aging of infrastructure in Japan is proceeding and that there are variations in the age of infrastructure between prefectures. Especially, the sewer system is especially aging in urban areas and has large variation between prefectures. The road is younger than others and the variation of age between prefectures is small. In the point of the problems about the maintenance of infrastructure, we must think about how to include the fairness in the system of infrastructure asset management. In addition, we have to decide how to set the level of safety in infrastructure through the information about the safety of infrastructure.
