...Title of a jiuta/koto song. The shamisen is played by Ishikawa Koto, and the koto is composed by Yaezaki Kengyo. It is one of the "Ishikawa Mitsumono" along with "Yae Goromo" and "Tooru". It is also called simply "Aoyagi" except when it is to be distinguished from the shamisen kumiuta "Aoyagi". The lyrics use the quirky parts of the Noh song "Yugyoyanagi". The song sings about a scene in which the wandering saint bestows a nembutsu on the spirit of an old willow tree he meets at Shirakawa Barrier, and the spirit appears in his dream and tells a story related to the willow, after which the conversation turns to kemari and the love story of Kashiwagi from the Tale of Genji. ...

It was a difficult piece that even Ishikawa himself could not play, but it became famous after Miyahara Kengyo (?-1864) had Yaezaki Kengyo play the koto.
