Commentary: Book Five Autumn Poems II 344

Headnote: "Composed on the topic 'Seeking Autumn Flowers at Dusk'"
Composed on the topic "Seeking Autumn Flowers at Dusk." As autumn deepens, at twilight when it is too dim to tell who anyone is, the scent of the thoroughwort drifting near feels, the emperor says, as if the flower itself were announcing its name. He deftly conveys the topic's idea of finding flowers by their scent in the dusk, when they are hard to see, through the personification of a flower naming itself.
The author, "Sutokuin Gyosei," is Emperor Sutoku, the seventy-fifth emperor and son of Emperor Toba, who was exiled to Sanuki after his defeat in the Hōgen Disturbance. He conceived the Kyūan Hyakushu and had Fujiwara no Akisuke compile the Shika Wakashū. A poem of his is included in the Ogura Hyakunin Isshu.
In a Kokin Wakashū poem by the monk Sosei, the scent of thoroughwort prompts the question of whose trousers have been cast off there, and the flower had long been sung of as joining scent with a person's name.

First line, "aki fukami": "mi" is a suffix of cause, "since autumn has deepened." Like "aki fukaku" in 332 of this book, it shows the season's deepening.
Second line, "tasogaredoki no": "tasogare" is the dim hour of dusk, and is a pivot word meaning also "ta so kare," "who is that?" It answers "nanoru," to give one's name, in the fourth line.
Third line, "fujibakama": the thoroughwort, one of the seven flowers of autumn, known for its scent.
Fourth line, "niou wa nanoru": "nanoru" is to give one's name, answering the question "who is that?" in the second line.
Fifth line, "kokochi koso sure": the emphatic "koso" closes with the perfective form "sure," "it truly feels as if it were naming itself."
