Watatsumi Okami is a Shinto sea deity, revered as ruler of the ocean depths and its tides, often invoked by fishermen, sailors, and coastal communities seeking safety and favor upon the waters. Traditions surrounding this kami emphasize its dominion over marine life and the sea's bounty, which has led some to associate it with prosperity and fortune tied to the ocean's resources. Shrines dedicated to Watatsumi Okami are found particularly in coastal regions of Japan, where offerings and rituals honor its enduring connection to maritime life.
