Kagoshima Bay in which the Kuroshio Current flows was formerly an abundant fishing area. However, in recent years, hauls of fish have been decreasing. It is thought that one cause is deteriorating water quality due to reduction of mudflats, which have clarification functions. However, the actual cause remains unclear. This organization located around the Shigetomi mudflats, Kagoshima was formed by the mudflat nature guide "Katamori." Dissemination and awareness-raising on mudflat conservation was conducted through observation meetings and survey research. However, as this work was limited to the activities of a single NGO, improvements to the environment did not proceed as envisaged. In this context, this NPO aims to create a network linking industry, governmental actors, acadamics and citizens through its own activities. These five parties will collaborate jointly with the aim of deploying a project to regenerate the Shigetomi mudflats, the sea, and the coastline. In addition, it will conduct regular environmental education to teach ordinary citizens about the mudflats, and create sustainable environmental conservation systems.
