ABSTRACT
Introduction Over recent years, the Japanese government has promoted measures to improve the development of tourism statistics. As a result, researchers now have easy access to information about tourism in Japan, such as surveys of visitor trends at well-known tourist attractions.1 However, it remains difficult to gather information on tourist traffic lines inside these venues because it costs too much time to check them. Therefore, no data are available for analyzing tourist traffic lines, and it is unlikely that the Japanese government will develop such a database in the near future, owing to its high cost. However, the analysis of tourist traffic lines is essential for developing the tourism sector in Japan.
