evidence: 213. The assessment of flood damage rates, defined as damage relative to underlying asset values, reveals that expected damage rates in 2080 surpass the present rates by, on average, about 20 percent. In absolute terms, the average damage rate for 1000-year floods rises from 28 percent to 32 percent by 4 percentage points (Figure 89). Similarly, for 100-year floods, the damage rate, on average increases by 5 percentage points. The profile of the increase in damage rates differs between these two flood hazards. For 100-year floods, the level of the 75th percentile rises, suggesting that areas already exposed to significant flood risk may face more severe disasters in the future. Conversely, for 1000-year floods, the level of the bottom 25th percentile moves up, indicating that wider areas could be at risk of experiencing severe flood damage once such an event occurs. Geographically, several prefectures, particularly in the Tohoku and Kanto regions, exhibit a heightened vulnerability to increasing flood hazards.
