Few studies have revealed the determinants of inbound tourists' behaviors in Japan quantitatively. Thus, our paper considers the empirical models to examine the willingness of foreign tourists to visit Japan. In particular, utilizing “tourism factors” as which we define what and to what degree foreign tourists care about when they choose the destinations, analyze determinants of their willingness to visit Japan. We have conducted an internet-based survey targeting the American tourists who have multiple outbound experiences. Our estimation results show that those who consider the elements of “meeting with people and interactions,” “attractions and tour spots,” “new experiences,” and “availability of public transportations” as the important factors have higher willingness to visit Japan. This study implies that it is crucial for Japan to enhance tourism resources and infrastructure in a way that meets their needs in order to promote the inbounding tourism.
