The present study aimed to design, develop, operate and evaluate a sightseeing spot recommendation system as a smart tourism tool that gathers and accumulates sightseeing spot information and considers personal preferences as well as priority conditions to support tourism activities, especially in urban tourist areas. The system was developed by integrating web-geographic information systems (Web-GIS), the recommendation system and the evaluation system. Additionally, the system was operated for 4 weeks in the central part of Yokohama City in Kanagawa Prefecture, Japan, and the total number of users was 62. Based on the results of the web questionnaire survey, the system was highly useful for sightseeing activities, and further utilization of each function can be expected by continuing the operation. From the results of access analysis of users' log data, it is evident that the system has been used by different types of information terminals just as it was designed for, and that the system has been used according to the purpose of the present study, which is to support the sightseeing activities of users. However, the number of visits to pages related to the evaluation function of sightseeing spots and submitting function of new sightseeing spot information was low. This may improve if the system operation is conducted on a long-term basis.
