The Japanese ukiyo-e artist Kitagawa Utamaro made a number of prints depicting ama divers—women whose work is to dive for shellfish or pearls—catching haliotis abalone sea snails. Amongst the prints are the first print in the erotic book Utamakura (1788); two triptychs called Awabi-tori (鮑取り, "Abalone divers"), one from c. 1788–90 and the other from c. 1797–98; and the hexaptych Enoshima Yūryō Awabi-tori no Zu (江之嶋遊りょうあわびとりの図, "Abalone divers hunting in Enoshima") of c. 1804–06. Utamaro's heir published the triptych Enoshima Awabi-ryō no Zu (江之島鮑猟之図, "Catching abalone in Enomshima") in the early 19th century, signed Utamaro.
