Abstract

At the time of the Heavy Rain Disaster in Western Japan in July, 2018, it was possible to gather and accumulate a variety of disaster information using the function of social media mapping included in our spatiotemporal information system. Considering these circumstances and taking up the above social media mapping, the present study described the issues related to the development and utilization of digital infrastructures as one of the measures for disaster prevention and reduction. As the results of the present study, it is possible to rescue and support victims, and cause excessive information and confusion, due to the close relationship between the real and virtual space in the super smart society of Japan. Additionally, it is essential to effectively utilize the information included in the virtual space at the time of disaster. Specifically, it is an important issue to make use of the information on social media for rescue in the real space. Furthermore, it is necessary to take the measures for the people vulnerable to disaster who require the disaster information most. For this, it is necessary to prepare a variety of ICT in addition to oral communication.
