In Japanese rivers, heavy and torrential rainfall and frequent attack of typhoons recently tend to cause extensive flooding. Therefore, local governments and residents need to share risk information to promote disaster mitigation measures and to reduce damage. Flood hazard map can be an important tool for this purpose. However, previous studies indicated that reading of a flood hazard map tends to affect inhabitants' risk awareness, but it is not effective enough for real preparedness. In this study, we conducted questionnaire survey in Iwakuni city and Houhoku town in Yamaguchi prefecture where flood hazard maps were distributed to inhabitants. Statistical analysis was applied to examine factors affecting change of risk awareness and preparedness assuming hypothesis. Risk awareness was found to increase as flood level becomes higher. Preparedness action was found to increase as risk awareness becomes higher and as people get older.
