Abstract
This study clarified the relation between the urban land formation process and the vulnerability to the tsunami disaster in the coastal tourism area.This is the Utsumi study area of Minamichita Town, Aichi Prefecture, which prospered as a beach from the Meiji Period. First, we prepared GIS data on land use from the topographic map from Meiji 26 to Heisei 26 in the Japanese Imperial Year. And we organized the city formation process from land use change. In addition, we cross-tabulated these land use data with the tsunami inundation supposed area and the city planning map. As a result, we analyzed the urban area formation process and the vulnerability to tsunami disaster in the Utsumi area. The Utsumi area was established as an agricultural area because it has one of the few flat areas of Minamichita Town.The flat area has been transformed from the agricultural land to the residential area together with the tourism landscape as a beach. There are many residential areas in the assumed area of tsunami flooding. There are no high-rise buildings and towers. Moreover, the compartment and the road are narrow. Therefore, the Utsumi area was established as a difficult area for horizontal and vertical evacuation.
