The Ino map was created by Japan's first modern surveying technology in the latter half of the Edo period (1603-1867). It has a wealth of geographical information centered on coastal areas and major highways nation-wide. In this study, spatial information analysis was used to link the geographic information found in the Ino map with the current hazard information, and to examine the manifestation of the inundation risk. As a result, it became clear that the disappearance of place names due to urbanization may have reduced the rate of inundation risk.
