Japan's population is decreasing and aging is progressing. The diligent and abundant labor force that has supported the economy will continue to decline, and improving productivity is a challenge. The “i-Construction,” which drastically improves productivity in all construction production processes from survey to design, construction, inspection, maintenance and renewal, is one of the important measures, and the i-Construction Report was compiled by the Ministry of Land, Infrastructure, Transport, and Tourism in April 2016. Based on the rapid development of satellite positioning technology and the Internet of Things, the report summarizes the viewpoints for advancing i-Construction in three categories: "Turning Construction Sites into Advanced Factories" "Introduction of advanced supply chain management at construction sites" and "Regulation of construction sites, breaking stereotypes and continuing "Kaizen"". As a top runner policy from these 3 perspectives, "Full utilisation of ICT (ICT earthwork)", "Optimal overall deployment" and "Leveling of construction time" were set, and the characteristic of this policy is that it lists the items to be tackled for each. In addition, as a mechanism for promoting i-Construction, it is proposed to develop a national promotion system, establish a public-private partnership consortium, utilise big data, collaborate with other outdoor industries, and expand overseas. This study evaluates and analyzes Japan's efforts from the viewpoint of the construction management research, and arranges how the construction management research is utilised in the policy practice actually carried out in Japan, and what is considered for the feedback from the policy to the research. In this paper, we reevaluate Japan's i-Construction efforts from two perspectives, (1) interdisciplinary perspective and (2) more practical implementation of research, which have been taken up in previous studies of Construction Management and Economics, to identify the keys to their success, and to verify the points of attention that contribute to both practical and research.
