Tourism is one of the most important industries in the world. An excavation of tourism resources is an effective approach to promote the tourism industry, and many excavation methods that have been devem Fortuitous Tourism Resources Candidates. Therefore, it is necessary to excavate Fortuitous Tourism Resources loped for Potential Tourism Resources that are resources with low name recognition and high attractiveness. However, an excavation method of Fortuitous Tourism Resources that are resources with high attractiveness by chance, due to influences of environmental factors, has not yet been developed. Fortuitous Tourism Resources are extracted froCandidates in order to find new Fortuitous Tourism Resources. In this paper, an excavation method of Fortuitous Tourism Resources Candidates, by analyzing data focusing on differences in familiarity of tourists, is proposed. Furthermore, we conducted a demonstration experiment in Kyoto, Japan, to practice the proposed method. As a result, three Fortuitous Tourism Resources Candidates are excavated using the proposed method, and the effectiveness of the proposed method is shown by the experiment.
