This study seeks to comprehend the actual state of use and the problem of subsidy systems for flood damage prevention in each residential area which are used as an individual support plan. We conducted a questionnaire survey on the aforementioned subsidy systems in 22 municipalities. We clarified that the subsidy systems are effective at the beginning, but the number of users decreased over time. This is because it is expensive to rebuild and raise the height of a building lot. Municipalities regard the wastewater treatment facilities as drastic measures. These measures need significant time and money. In a flood-assumed area that has never experienced flooding damage, neither municipalities and residents implement measures for flooding risk. Although the residents who use subsidy systems are limited, municipalities should promote these systems to the target that tends to use subsidy systems, such as companies that treat precision instruments.
