This study explores differences between VR and on-site sightseeing experiences among Japanese and Chinese subjects, focusing on sightseeing behavior, caption evaluation, and psychological evaluation. By examining how prior knowledge and experience affect differences, the study finds Chinese subjects, less familiar with destinations, behave more similarly in VR and on-site than Japanese. However, their intention to visit the site remains strong after the VR experience. These findings suggest that for foreign visitors like the Chinese, enhancing VR sightseeing applications by incorporating novelty and cultural uniqueness can improve satisfaction and encourage more on-site visits.
