Umibozu is a rare spirit of Japanese folklore that lives at the bottom of the sea and capsize any ship whose captain or crew dares to speak with him. According to the story, when Umibozu was angry he asked the crew members for a wooden barrel. The creature filled the barrel with seawater to drown the nafegantes so that they could not escape. To avoid the final destination the only solution was to give it a bottomless keg. This legend is related to a Japanese tradition that says that the souls of people who have no one to care for their graves will take refuge in the sea. The name given to this creature combines the character of the sea with the character of the Buddhist monk.
