English Translation
After how many ages
could I ever forget it—
soon to scatter,
the bush clover of the fields
and the moonlit night that polished it
Meaning
How many ages must pass before I forget this moonlit night, polishing the autumn bush clover of the fields that will soon scatter?
Commentary
Book Six Autumn Poems II 317

Headnote continued from the preceding poem: "Composed as an autumn poem."
The poet says he will never forget, however many ages pass, the moonlit night that seems to polish the bush clover of the fields, soon to scatter. It praises the beauty of bush clover on the verge of falling and the clear moonlight shining on it.
From this poem on, the book continues with poems on the autumn moon.
The poet, called "Fukayabu," is Kiyohara no Fukayabu. Said to be a son of Kiyohara no Fusanori, he served as a secretary in the Bureau of Palace Craftsmen, among other posts. He was the great-grandfather of Sei Shōnagon and was also known as a master of the koto. His "natsu no yo wa mada yoi nagara akenuru o" is included in the Ogura Hyakunin Isshu.

The first line, "Ikuyo hete," means "after how many ages."
In the second line, "ka" is a rhetorical particle forming a kakarimusubi pattern with the attributive "n": "would I forget it later?"—meaning he would not. The poem pauses here.
In the third line, "nubeki" combines intensification and conjecture: "that is sure to scatter."
The fourth line, "nobe no akihagi," means "the autumn bush clover of the fields," the same words as the last line of 298 in this book.
The last line, "migaku tsukiyo o," means "the moonlit night that polishes," standing in inversion with the second line. The moonlight is seen as polishing the bush clover until it shines.
