This study discusses about people’s risk perception of National Seismic Hazard Maps for Japan. Seismic Hazard Maps is made by Headquarters for Earthquake Research Promotion. And the aim of this map is to make people think about risk and promote disaster prevention measures. To confirm whether the map fulfilled the role, we conducted a survey in March 2017, and got responses from 2400 people. From the analysis, it proved that people feel likely to be affected the expression of “will happen of Y % probability” more than by the expression of “will happen within X year(s)”. And people who can understand the map tend to sensitive to fear of the earthquake and risk of their place of residence.
