The Ino map, which was completed at the end of the Edo period, contains spatial information such as village, county, temples, shrine, castles, and natural place names, in addition to location information such as coastlines and roads at that time. We thought that the effect of the effectiveness on the temporal and spatial changes of tsunami disaster place names and the risk of natural disasters could be verified by utilizing this old spatial information. In this study, we investigated the existence rate and disappearance time of tsunami disaster place names in the Ino map extracted by spatial information analysis, and evaluated the risks of various natural disasters.
