Abstract

This study uses stock data on infrastructure in Japan from “Measuring Infrastructure in Japan 2017”, released by the Japanese Cabinet Office, to elucidate the current situation of aging infrastructure in Japan. An aging indicator based on stock data shows that there are differences in aging between infrastructure sectors, but almost no differences in degree of aging due to city scale. Additionally, the results show that aging has occurred in all infrastructure sectors, and that there is inadequate commitment of resources to maintain infrastructure quality.
