The Ichikawa River that runs through Hyogo Prefecture is a habitat for the Japanese giant salamander, a nationally protected species. The Hanzaki Institute of Japan is using the Kurokawa Elementary and Junior High School building, which was previously abandoned, as a base for collaborating with other organizations to conduct research, develop habitat restoration methods, and support educational and training initiatives with the aim of restoring and conserving the local environment. This project aims to strengthen the organization's base, consolidate activities and improve their content by holding giant salamander and forest green tree frog observation events, riverside education sessions, eco-tours, and other events. These activities will raise issues facing the river ecosystems in which these giant salamanders are the top predator, giving participants a chance to consider how they should interact with nature.
