Heavy-rainfall in July, 2018 caused inundation and landslide disaster in Western Honshu, Japan, and the toll of death and missing rose to 245. This paper aims to clear the characteristics of evacuation behaviours in the rainfall through a questionnaire survey, focusing on Situation Awareness, to residents exposed to the hazards . As results, it was cleared that among the damaged residents, the only 15% of them actively evacuated with success in situation awareness of official warnings and recommendations, and the 20% of them passively evacuated by direct callings to evacuator or visual confirmation of approaching the hazards, but the others did not evacuate. This result implies it is important to support not only situation awareness of official warnings and recommendations but also to direct callings in communities to make up for the failure of the situation awareness.
