Primatology in Japan after the World War II began in the late 1940s with the observation of shy wild Japanese macaques (<i>Macaca fuscata</i>) from more than 100 m. Depending on artificial feeding students succeeded to observe macaques within a short distance and identified each individual. Individual identification of calm free-ranging macaques within a short distance made it possible to record individual and social behavior of each identified individual in detail; long-lasting kin-recognition between a mother and her offspring, dominance relations among individuals and kin-groups, and then, social organization. Artificial feeding is a form of semi-experimental manipulation introduced into the wild monkey groups. This paper showed how students contributed to the primate studies under such a condition at Koshima, Takasakiyama and Katsuyama. Some behaviors, particularly cultural ones, were found only in the artificially-fed groups. Some other exceptional or uncommon phenomena or behaviors seen in non-artificially-fed groups were recorded, with many episodes sufficient for statistical analysis at artificially-fed groups. As far as we are cautious that artificial feeding is semi-experimental manipulation on the wild monkey groups, we can find out more about the important nature of human and non-human primates and evolutionary relations of them.
