The Ungyoku-Waka-Sho is a collection of waka poems compiled in 1514 by a poet of unknown origin called Noso-Junso in Motosakura, Shimousa Province.
Of the approximately 580 waka poems in theare included, but approximately 200 are privately selected waka poems. This anthology has a strong connection with Noh song. Therefore, this paper take up Yukioni, Kakitsubata, and Basho, and considers their acceptance of the Ungyoku-Waka-Sho.
Yukioni is an abandoned Noh song that seems to be made by Konparu-Zenchiku, but its outline can be seen in the Ungyoku-Waka-Sho. This is a good example of how the Ungyoku-Waka-Sho shows the influence of waka poems. The theme is the legend of Ariwara-no-Narihira, which is related to Yukionna in Katano. Both Kakitsubata and Basho are made by Konparu-Zenchiku. Kakitsubata is based on the Ise-Monogatari and is strongly influenced by the old notes of it.
In other words, the Ungyoku-Waka-Sho is also an attempt at a new creativity based on a different the old note. The main theme of Basho is Basho-no-yabure, and the historical fact that Ota-Dokan died sideways can be seen from the friendship of Noso-Junso in the Ungyoku-Waka-Sho.
From these cases of three Noh-songs have a common theme of "all things have the Buddha nature" which is the teaching of the Lotus Sutra.
The source is the phenomenon caused by water.
