What are human beings? What are minds that question about human beings? Starting with such questions, I have entered into the academic world to study nonhuman primates from comparative cognitive perspectives. The main target of my research is the chimpanzee, one of the closest living relatives of humans, since my graduate course. I would like to explore the evolution of human mind through the investigation of social intelligence in great apes. I am currently the Director of Kumamoto Sanctuary, Wildlife Research Center, Kyoto University. I have also started studying non-primate species such as wild horses.
