Hair characteristics of Japanese monkeys were investigated and geographical variations of them were recognized. Namely, the Japanese monkeys inhaviting in the high latitude areas or in the cold climate tend to have relatively short hair with medium density, and those inhaviting in the warm and rainy climate tend to have long hair with low density. Because these geographical variations are closely related to the climate where the Japanese monkeys are inhaviting, it is concluded that the hair characteristics are one of the adaptive forms to the varied complicated weathers in Japan. On the other hand, to compare with other macaques, the Japanese monkeys have higher density of hair than the other macaques. Hair with high density seen in the Japanese monkeys is considered to be suitable to the cold climate in Japan located in the highest latitude as the habitats for nonhuman primates.
