Currently, the development of ICT integrated cross-sector smart city associating transportation, energy, security, and more is underway to mitigate various urban problems in Japan. There are numerous roadblocks that hinder the development of the cross-sector smart city, and thus delaying the optimization and utilization of data for development. Therefore, this research focused on a digital twin city by recreating in cyberspace and examined the required data, and obstacles in establishing a cross-sector smart city. Further, this research compared Regional Hub Cities in Japan and advanced foreign model cities to understand the issues surrounding the data platform in Japan. In order to solve urban problems, we suggest measures such as the establishment of public and private sector integrated platforms, the implementation of sensing equipment to grasp the microscopic real-time city behavior and disclosure of data to promote public and private partnerships.
