It is important for islands to understand and conserve the current state of water resources such as drinking water, and to understand how substances circulate and flow out to the surrounding sea area in the water circulation centered on rivers. It’s also necessary for the marine environment and marine resources. Comprehensive research using the theory of hydrological science, which clarifies the material circulation that accompanies the water circulation, and the method of “aquatic geography,” which elucidates the effects of humans based on “natural magazines,” is an island. It is effective for water environment research in Japan, and has been conducting continuous research on various islands such as the Izu Islands, Yaeyama Islands, and Nagasaki Islands. Although Sado Island has the area next to the main island of Okinawa except for the four major islands in Japan, sufficient research on the water environment has not been conducted, so we conducted field surveys three times in 2019 and once in 2021. Based on the results, we grasped the current situation and considered the effective and continuous utilization of water resources from the viewpoint of hydro-geography.
