Commentary
Book Eleven Love Poems I 1046

Headnote: "Reply."
This is the fifth poem of the sequence on love sung through the things of the Fifth Month, a reply to the preceding poem. Though the cuckoo sings in a hushed voice, its song has leaked from the oak grove and been heard, she answers, playing on the oak as a name for Michinaga, then Assistant Captain of the Military Guards. According to the headnote, it is a reply to Fujiwara no Michinaga's poem.
The author, "Uma no Naishi," was a lady-in-waiting and poet of the mid-Heian period, one of the Later Thirty-Six Poetic Immortals.

The first line, "hototogisu," takes up the first line of his poem.
In the second line, "mono o" is concessive: though it hides its voice. The soft first songs of the cuckoo in early summer were called "shinobine," hidden notes.
In the third line, "kashiwagi" is the oak, and since the leaf-guarding god was said to dwell in it, it became another name for the Military Guards and the Gate Guards who protected the palace. It points to Michinaga as Assistant Captain of the Military Guards.
In the fourth line, "mori" pivots between "mori," leaking, and "mori," grove. It is the same wordplay as "mori no tsuyu" in 1031, Yoshitsune's poem.
The last line, "kikoekeru kana," means "it has been heard," closing with the exclamatory "kana." Where his poem sang of the hesitation of a first courtship with "mada fuminarenu," she lightly parries that though he means to hide it, word of him has leaked out all the same.
