Planetary defense research is research to respond to disasters that threaten human civilization. When looking at planetary defense from the perspective of disaster research, it covers not only research in fields such as earth and planetary sciences and aerospace engineering, but also a wider range of natural sciences, as well as research in the humanities and social sciences. Behavioral research is needed. Compared to ordinary disaster research, the degree of awareness of disasters and the extent of their impact are different, and basic information such as the degree of awareness is first necessary in order to understand the decision-making process for countermeasures and actions. In 2022, as one of the hard-to-choose issues in various fields, we piloted a social survey of internet monitors about the use of nuclear devices as a last resort to change the trajectory of NEO. Furthermore, in 2023, we will conduct a survey specializing in planetary defense, which is currently being analyzed. Both surveys included 1,000 Japanese adults. Awareness of planetary defense was about 30% in terms of name and content. In the choices for the presented collision avoidance scenarios, some of the choices were changed when the setting was changed to the possibility of falling in the area where one lives, while some answered that it would be left to the judgment of experts. There was a tendency to leave the judgment of experts as it is even for changes in areas where there is a relatively large number of conflicts and there is a possibility of collision. This report provides an overview of the survey. This research was supported by the Toyota Foundation Research Grant (Grant No. D19-ST-0019).
