###### Abstract  
In tourist areas, it is necessary to prepare a method that supports tourists' activities by providing information concerning disaster support facilities during normal times, in addition to sightseeing spots and tourism-related facilities, because there is a risk of confusion during disasters, as tourists are not aware of the locations of disaster support facilities. The present study aims to develop a navigation system that supports the activities of users during both normal times and disasters by integrating augmented reality (AR) and web geographic information systems (Web-GISs), as well as by using pictograms. The system can not only effectively provide users with information concerning sightseeing spots and tourism-related facilities but also information concerning disaster support facilities. The system was operated over a period of 6 weeks in Chofu City, Tokyo Metropolis, Japan. Based on the results of a questionnaire survey for 60 users, the system was highly evaluated for its originality in terms of displays and functions using pictograms, navigation using AR, and obtaining information during disasters. Additionally, based on the results of access log analysis, the system was continuously utilized by users during the operation period. Therefore, by continuously operating the system, it can be expected that users will further utilize each function of the system. sightseeing navigation system; augmented reality (AR); location-based AR; pictogram; web geographic information systems (Web-GISs); sightseeing; disaster +

For example, tourists can look up information concerning the locations or destinations that they want to visit using their mobile information terminals while sightseeing. However, in areas that they are not familiar with, they may lose track of the routes or direction of their destinations even after referencing a map. Additionally, there is a risk of confusion during disasters, as tourists are not aware of the locations of disaster support facilities, such as evacuation sites and shelters in the tourist areas. Therefore, a method that supports tourists' activities by providing information concerning disaster support facilities during normal times, in addition to sightseeing spots and tourism-related facilities, is necessary. On the other hand, a technology called AR (augmented reality) has attracted attention as a method to efficiently provide information. AR is a technology that visualizes information by displaying digital contents such as images or videos in the real world using wearable devices such as smart glasses (Konoike) [4]. Additionally, [PERSON] et al. [5] surveyed mobile AR and presented its advances in tracking and registration and the existing challenging problems. There are various AR types, including location-based AR, which uses the location data obtained from a global positioning system (GPS), the image recognition-based AR, which recognizes images and markers, and markerless AR, which recognizes flat surfaces and spaces. Information technologies developed using AR include not only applications that support sightseeing and disaster prevention (GrapeCity) [6], but also applications such as Pokemon Go, which are developed together with a GPS that can be used in the real world. In this way, AR applications have become familiar to the general public. Additionally, AR is used in many ways and in various situations, and it is also used as a method to provide sightseeing information. The results of preceding studies, in which a navigation system for sightseeing as well as a system to provide sightseeing spot information were developed using AR, ([PERSON] et al. 2014, [PERSON] et al. 2016, [PERSON] et al., 2016, and [PERSON] et al.
