This study reports the results of a post-disaster survey for residential environment in Chiba Prefecture after Typhoon Faxai on Sep. 9, 2019. Besides to damage surveys for houses caused by strong winds, questionnaire surveys on the residential environment, which inquired about the change of the residential environment after the disaster, were conducted. As the damage of roof becomes severe, the number of houses responding to “water leakage” increases. When the damage ratios of the roof were 10%, the response rate to “water leakage” was 30%.
