Abstract
During the heavy rain in July 2018, emergency warning was issued by Japan
Meteorological Agency, and evacuation orders and recommendations were issued by
municipalities. In fact, many people, however, did not evacuate and stayed at home. This study
conducted a questionnaire survey in Nishikyo Ward, Kyoto City, where there was concern
about the flood of Katsura River and for which an evacuation order (emergency) was issued.
The survey aims to investigate the relationship between personal attributes such as differences
in the recognition of disaster and the actual situation of evacuation behavior. Results show that
there is a relationship between perception of river flooding and evacuation behavior. Even after
obtaining evacuation order, low percentage of people evacuated. The reasons for the failure
to evacuate indicate the surrounding conditions such as weather condition and time affected
the evacuation behavior. Despite recognizing that the house was expected to be inundated by
the inundation hazard map, few people actually evacuated, indicating that there was cognitive
dissonance.
