In this study, I focus on the Nishi-ohdai Regulated Utilization Area (RUA) of Yoshino-Kumano National Park, which was designated as the first such area after the RUA system was established in accordance with the Natural Parks Law. The study was based on the research on trends in visitors to the area and the questionnaire survey results, both of which have been conducted by the Ministry of the Environment (MOE) since the RUA designation was launched. In conclusion this study clarified that, in the area, about 97% of visitors have no perception of crowding and the visitors who expected to see the primeval atmosphere feel satisfied on the whole. I think this conclusion indicates the effect of RUA. The study was also examined from the perspective of the guide use in consideration of the future utilization method of the RUA based on the analysis result of questionnaire surveys.
