An onmoraki is a bird-demon created from the spirits of freshly-dead corpses that appears in Shinto mythology. They resemble a black crane, and if a person is caught sleeping in a temple's sermon hall, the onmoraki will rebuke them while flapping its wings. Onmoraki are also said to shout the Degeneration Sutra in the household altar of priests who neglect to read their sutras.
In modern Japanese art, the onmoraki will often take on the comical appearance of a roasted chicken. This is most likely due to the works of an eighteenth century artist, Toriyama Sekien.
"A type of specter found in Japanese legends. Onmoraki are former humans whose spirits have been transformed by hatred because they did not undergo rites of purification after they died. They appear as cranes with human heads and forked tongues. They shake their feathers and wail in high-pitched human voices. The greatest desire of the Onmoraki is to undergo purification rites, and they are said to appear in Buddhist temples. They are also known to appear to monks who are lax in reciting their sutras."
