Design thinking has been attracting attention as a human-centered, creative, and pragmatic approach for innovation. It also offers feasible solutions to multi-layered and complex problems in society. This study examines an application of design thinking on the development of a tour as a case study in which female second-year college students designed and implemented a day bus tour for female students to Yamashiro Onsen, one of the spa resorts in Kaga City, Ishikawa Prefecture, Japan. This case study shows that design thinking was effective in designing an entirely new tour that discovered potential needs.
