Yūzuru

(Twilight Crane), is a Japanese opera in one act composed by Ikuma Dan after the play of the same name by Junji Kinoshita.

Ikuma Dan initially wrote incidental music for Kinoshita's play in 1949. Later, determined to transform the music into an opera, he approached Kinoshita who agreed to release the play under the condition that it was set to music word for word. Dan started composing the opera and finished the work a year later in 1951. The première was held at Osaka Asahi Hall on January 30, 1952.
