Aiming to understand distribution of exposed value throughout Japan in the 21st century, this study quantitatively analyzed risks of earthquake, flood, and sea-level rise using 500m mesh with population, asset, and geospatial information. The following presents the results.1. 25.5% of the residential area, 50.9% of the population, and 36.9% of the assets are in the areas with altitude of less than 25m.2. Population and assets are more concentrated in areas at high risk of sea-level rise than in areas at high risk of earthquakes and flooding.3. Places with higher disaster risk have lower rates of population decline.
