or kaijin.
Kami of the sea. The deity popularly associated with the sea and lakes is the Taoist dragon-deity ryujin whose palace (ryugu) lies beneath the waves and can be identified with tokoyo. Since the sea figures largely in Japanese life there are many other kami connected with the sea and safety at sea who are worshipped as kaijin. These include the Sumiyoshi kami, Munakata-no-kami, Ebisu, Hachiman, and funa-dama.
