The purpose of this study was to estimate the economic damage from land loss caused by potential inundation due to sea level rise by 2100 in the coastal areas of Japan, and to compare this estimate with those calculated by conventional estimation methods. We used the posted land prices for residential land and the prices of rice paddies, crop fields, and timber forests to estimate the economic damage from land loss. Average land prices were calculated and interpolated for each municipality. Inundated area and economic damage were calculated under three scenarios: SSP1-2.6, SSP2-4.5, and SSP5-8.5. The potential inundated area nationwide in 2100 was estimated as 2,542-2,707 km² (SSP1-2.6 to SSP5-8.5). The economic damage varied from 158 to 200 trillion yen (SSP1-2.6 to SSP5-8.5) in 2050 and from 185 to 428 trillion yen (SSP1-2.6 to SSP5-8.5) in 2100.
