In July 2022, we signed a cooperation agreement with Kyoto  University’s Field Science Education and Research Center for the New Satoyama‒Satoumi Co-Creation Project, promoting co-creation through education, research, and collaboration. Under the Connectivity of Hills, Humans and Oceans (CoHHO) framework, we share fieldwork findings and support joint studies, including test site activities, biological surveys, study sessions, and community engagement.
