This was originally produced by the University of the Air in Japanese as video course material. Later the scripts were translated into English and narrated by Michael A Huffman (Kyoto University) in collaboration with Professor Itani to share the information with an international audience. The species presented in this series represent some of the many important field sites featuring a diverse range of primate species around the world pioneered by Japanese primatologists of Kyoto University. Prof Itani, featured here toward the end of his career introduces each site and sets the stage for the on-site presenter, a primatologist responsible for the long-term work conducted at each site by his students over the years.
