The primary purpose of this research is to get a hold of the polders that are embanked from the flood control project. And the secondary goal is to show how the flood control projects influence the living environment by grasping the overall situation on the population and number of houses at the Kihocho, Mie Prefecture after the project is being performed.
 First of all, Japan suffers from the flood damage frequently every once in a while. People are fighting the flood since centuries ago. However, flood control is still a major problem today even with proper technology and equipment due to the increase of precipitation these couple of years. Then, the government of Japan founded a flood prevention organization in December 2015 to help people to change their way of thinking towards flood disaster.
 To begin the investigation, a bibliographic and hearing survey is performed throughout the flood controls project that completed around the nation. After that, an actual investigation is performed around the basin of the Ainoya River in Kihocho, Mie Prefecture after the disaster. Finally, another bibliographic and hearing survey is conducted to capture the data of the population and number of houses in Kihocho. As a result, the numbers of population and houses increases after the flood control project is performed, and on the other hands, the population decreases as the flood strike. And the data shows the growth in the number of houses after the flood occurs in the year of 1997 and 2011. Next, by focusing on the landform, the damage from the flood is lower on the highlands. However, when the damage from the flood occurs during an unpredictable situation leads to a decrease in the number of households. And the lowland area that suffers great damage from the flood also tends to have a significant reduction in the number of houses. We have confirmed that many homes in the region are being rebuilt and also raising their levels to prevent the damage from the flood.
 Therefore, it is critical to get prepared for yourself instead of depending heavily on the flood control by the government.
