## 7 Conclusions  
In areas that tourists 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 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. Against such a backdrop, the present study consisted of designing and developing the system (Sections 3 and 4), followed by its operation (Section 5), evaluation, and identification of improvement plans (Section 6), which can be summarized in the following three points. Additionally, the present study targeted an urban tourist area in Japan where various kinds of information and communication technology (ICT) are available. 1. In the present study, a navigation system integrating AR and Web-GIS while using pictograms was developed. The system adopts AR and Web-GIS to effectively provide users with not only information concerning sightseeing spots and tourism-related facilities, but also information concerning disaster support facilities. By adopting AR and Web-GIS, users can obtain information concerning sightseeing spots and tourism-related facilities as well as disaster support facilities at any time. With this, even while sightseeing, users can easily obtain disaster information in addition to sightseeing information. 2. The operation target area was set to Chofu City in the Tokyo Metropolis as an urban tourist area, and the system was operated and evaluated. The system was operated over a period of 6 weeks (from late November to early January) with people inside

A questionnaire survey was conducted for 60 users, and the response rate was 100%. The system was used not only by youths but by various age groups, and there was no difference between such age groups regarding the answer tendency. 3. Based on the results of the questionnaire survey, the system was evaluated highly for its originality in terms of displays and functions using pictograms, navigation using AR, and obtaining information during disasters. Thus, though the rating for operability during disasters was somewhat low, the present study indicated that the system could also be used as a method to obtain information concerning disaster support facilities. Additionally, based on the results of the access log, the system developed in the present study 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. As for future research subjects, the improvement of the system based on the results in Section 6.3, as well as the enhancement of the significance of using the system by gaining more data from other urban tourist areas inside and outside Japan, can be raised. [PERSON] design, develop and operate the sightseeing spot recommendation system that takes into account the visiting frequency of users in the present study. He also initially drafted the paper. [PERSON] carried out background work and evaluates the system. Both authors have read and agreed to the published version of the manuscript. This research received no external funding. The study was conducted according to the guidelines of the Declaration of Helsinki and approved by the Institutional Review Board. Informed Consent Statement: Informed consent was obtained from all subjects involved in the study. In the operation of the sightseeing navigation system from normal times to disaster outbreak times and the web questionnaire survey of the present study, enormous cooperation was received from the participants, mainly in the Tokyo metropolitan area.
