Amid fears of more severe disasters due to climate change, wide-area evacuation for people to leave the city in the event of river flooding is being discussed. In this study, through a wide-area evacuation workshop conducted for residents of Settsu City, Osaka Prefecture, where the necessity of wide-area evacuation has been pointed out, we analyzed factors effective in changing residents' awareness toward wide-area evacuation. In the workshop, we examined appropriate wide-area evacuation for the participants by using the “wide-area evacuation drill,” which consists of three steps: (1) prior awareness (before information confirmation), (2) risk information (confirmation of risk information), and (3) post awareness (after information confirmation). From the results of the wide-area evacuation drill and the questionnaire survey, it was confirmed that the process of confirming and comparing one's own prior awareness and correct risk information through the wide-area evacuation chart fosters awareness of early wide-area evacuation, and that the time factor is effective in changing residents' awareness of wide-area evacuation.
