This paper aims to examine causal effect of residents' recognizable and tolerable troop size of wild Japanese macaques causing damage in the northern area of Mt. Fuji, Yamanashi prefecture. We conducted 1) damage risk estimation, 2) questionnaire survey to residents living within 300m from forest edge and 3) structural equation modelling to estimate optimal causal effect model. Consequently, 41.5% of questionnaire was responded, and many of respondents underestimated troop size causing damage. We proposed that reduction of damage perception was priority issues because it positively influenced residents' perception of troop size.
