The Ino map is a map created by Japan's first modern surveying technology based on the results of the 1st to 10th surveys (1800-1816) conducted by Tadataka Ino in the latter half of the Edo period. In par-ticular, with the intention of capturing the entire country, information on the coastal areas of the whole country is literally enriched. In this study, we investigated the transition of the coastal environment over the past 200 years by linking the spatial information (coastline and coastal place names) of the Ino map with the current environmental information by spatial information analysis. As a result, it was possible to grasp the changes in the coastline from the time of making the Ino map, the degree of disappearance of sandy beaches in the coastal area, and the degree of reduction in the risk of tsunami damage due to de-velopment in all the coastal prefectures to be analyzed.
