Prefecture level and city–town level population exposure to heavy rain disaster risk was analyzed, specifically examining flooding and landslides. Populations of many prefectures are expected to be exposed to heavy rain disasters. Ratios of populations exposed to heavy rain disasters are also increasing. Particularly, it is noteworthy that flood risks are expected to increase. Consequently, land use planning should incorporate flood risk consideration. Results show decreasing trends of landslide disaster risks. Findings suggest that the disaster risk characteristics differ among cities and towns.
