"Mujo", as a Buddhism term that was introduced to Japan in its early eras, is the expression of the non-stopping shifting of the love, lives or emotional states. In the expressions of Japanese authors, it always came with some tragic events or blue emotions; from the earliest Tanka in Manyoshu to The Tale of Genji, Mujo as a common factor of transition was widely used in all genres of literature. Although it was presented in different kinds of platform with different purpose, Mujo, with the tragic color of itself, was used in most of the works to perform a unique sense of beauty; the fade of cherry blossom, the changing of the full moon, all the characters were presented to voice the emotion of the authors that was about the fading perfectness, which needs us to treasure more.

Naturally, these kinds of understanding were reflected by the description of the natural scenes that presented the beauty of Mujo in a more inverted way.
Essays in Idleness, the collection of prose by Yoshida Kenko, was one of the most representative literature works during the Muromachi period. During this period of the Japanese history, the literature works showed a big trend of tragic symbolism as the development of the "fade of flower and leaves" of the prior periods. In the Essays in Idleness, Yoshida stated that:
“Nay, to look out on the rain and long for the moon, to draw the blinds and not to be aware of the passing of the spring—these arouse even deeper feelings…Men are wont to regret that the moon has waned or that...
