Compared with the existing studies, the contributions of this articleare as follows: first, this study focuses on Japan, where climate changehas been significant, and investigates the sensitivity of the popularmaple leaf tourism in autumn to climate change. Our research helpsreduce the uncertainty in the impact of climate change on tourismcaused by differences in tourism types and regions. Second, existingstudies in the field of phenology focus more on the ecological and environmentaleffects resulting from the changes in phenological phasesand less on the effects of vegetation changes on human economic activities.Our study provides perspectives to study tourism and climatechange with the use of long-term, time-series phenological data, whichhelps resolve the lack of observational data in tourism research andfurther deepens the study of the relationship between tourism and climatechange. At the same time, it expands the field of phenology.
