This study explores the potential demand for a bear-watching tour under consideration in Daisetsuzan National Park, Hokkaido, northern Japan, using choice experiment. The brown bear (Ursus arctos yesoensis) is representative of land mammals in Hokkaido. Local residents have overlooked to recognize bears as a potential tourist attraction; however, a bear-watching tour could provide benefit for local residents. Previous studies have shown that this kind of tour also improved wildlife management. A questionnaire survey was conducted in September 2008, and 302 responses (50.3%) were returned by mail. After removing respondents who were not interested in the tour, we analyzed the remaining 190 completed responses. Conditional logit model estimates demonstrate that the willingness-to-pay for the ideal tour, which is the best combination of tour destinations, group sizes, information services and probability of finding bears, is 8,804 JPY; thus, the tour would be profitable for the local residents. However, mixed logit model estimates show that hikers have heterogeneous preferences for tour destinations and information services. Therefore, varieties in terms of tour destination and information services are required to meet hikers' demands.
