System Design of a Mobile Application to Support Foreigners Staying in Japan at the Time of a Disaster

Various natural disasters occur all over the world. Under such circumstances, research is being actively conducted to predict natural disasters and reduce the damage caused by disasters. In addition, the development of mobile applications for obtaining and sharing information in the event of a disaster is also active. Japan is a country where disasters such as earthquakes, typhoons, heavy rains, and floods occur almost every year, and technological development and service operations to mitigate the damage are active. In Japan, social media, especially Twitter, is used as an effective way to collect and share information at the time of a disaster. However, most of the disaster information systems are supposed to be used by Japanese people, and most of the information distributed during a disaster is in Japanese. In this paper, we consider the system design of a mobile application to support foreigners staying in Japan in the event of a disaster.
