The Sea Monk (Umi Bozu) is a sea monster with a smooth round head, like the shaven head of a Buddhist monk. This print illustrates the story of the sailor Kawanaya Tokuzo, who decides to go to sea on the last day of the year. A violent storm breaks out & the Umi Bozu appears. In a ghastly voice the apparition demands, "Name the most horrible thing you know!" Tokuzo yells back, "My profession is the most horrible thing I know!" The monster is satisfied with this answer and disappears.
