In this study, we compared the questionnaire data related to evacuation behavior, obtained in Hidaka city, Hokkaido in 2014 to another questionnaire, obtained in the same area right after the Great East Japan Earthquake. Moreover we analyzed the adaptation of disaster prevention awareness from those data. Then, we found that normalcy bias prevented residents from becoming active for disaster prevention. After that, we classified awareness of residents by 5 phases from questionnaire data and found that existence of close people made normalcy bias suppress. Additionally, we also found that the psychological closeness with the close people was one of the suppression factors for normalcy bias.
