Hanekazura ima suru imo o urawakami iza isakawa no oto no sayakesa

はねかづら今する妹をうら若み
いざ率川の音のさやけさ

Roma-ji: Hanekazura ima suru imo o urawakami iza isakawa no oto no sayakesa
English Translation: Newly adorned
with a feather wreath, the girl
is so young and fresh
I say "Come!"—the Isa River,
how clear the sound it makes!
Meaning: "Come now!" I would say to the young girl just crowned with her feather wreath—and so to the Isa River, whose sound runs so pure and clear.
Commentary: Book Seven Miscellaneous Poems 1112

Headnote continued from the preceding poem: "On Rivers"
The first three lines mean inviting with "iza" (come!) a fresh young girl who has just put on the feather wreath marking her coming of age, and they form an introductory phrase leading to the place name Isakawa. A poem praising the clear sound of the Isa River is thus touched with the gaiety of a lover's invitation.
The Isa River flows from around Mount Kasuga through the capital at Nara. The last line, "how clear the sound it makes," is the same as in poem 1102 in this book. The poet is unknown.

The first line, "hanekazura," refers to a hair ornament said to be worn by girls as a sign of coming of age.
The second line means "the girl who is now wearing it."
The third line, "is so young and fresh," is a "-mi" form meaning "because she is so young." The first three lines form the introductory phrase leading to the call "iza."
The fourth line plays on the invitation "iza" and the place name "Isakawa."
The final line ends with a noun, expressing wonder at the purity of the river's sound; it is shared with poem 1102.
