- Not to be confused with Uto han.
- Japanese: 善知鳥 (Utou)
Utô is a Noh play about a fisherman who hunted utô birds (known as rhinoceros auklets in English), and who is now tormented by giant birds in the afterlife, as a result of the Buddhist laws against killing other beings. A significant portion of the play is taken up by the ghost's relating of his tale.
