From the darkness of Kojo Park, along with mysterious music, the opening scene emerges like a vision. The scene shows the daily life of people in the Nara period. In those days, the provincial office of Etchu was located in what is now Takaoka City and the governor was young Yakamochi Otomo who is now well known as the compiler of the MANYOSHU.
One afternoon in early spring with plum blossoms blooming all over, Yakamochi goes boating on Lake Fuseno-Mizuumi with a courtesan, Hanishi.
Fuseno-Mizuumi used to be a beautiful lake, which has been drained for cultivating rice. The Manyoshu says that Yakamochi often enjoyed composing poems with courtesans and his followers on a boat there.
Yakamochi is concerned about the political situation of the capital which is at the zenith of its prosperity, just like gorgeous cherry blossoms at their best.
The Fujiwara family is increasing its power, while the Otomo family is not as powerful as before. With the matter on his mind, Yakamochi falls asleep with his head on Hanishi's lap.
Nymphs of the lake dance gracefully to Yakamochi's poem, "An Ode to Mt. Futagami. "The muse of Mt.Futagami, seeing Yakamochi's worried look, takes him on time travel to the future his dream.
