Asagumori hi no iriyukeba mitatashi no shima ni oriite nagekitsuru kamo

朝ぐもり日の入り行けばみ立たしの
島に下り居て嘆きつるかも

Roma-ji: Asagumori hi no iriyukeba mitatashi no shima ni oriite nagekitsuru kamo
English Translation: The morning is dim,
and as the sun goes into cloud,
to the garden isle
where he used to stand, I went down
and sat there in my grief.
Meaning: The morning was overcast, and as the sun went into the clouds I went down into the garden where our prince used to stand, and sat there grieving.
Commentary: Book Two Elegies 188

Headnote continued from the preceding poem: "Twenty-three poems composed in grief by the attendants of the Prince's palace"
As the overcast morning sun goes behind the clouds, the speaker goes down into the garden where the prince once stood and sits there in grief, laying the darkness of his heart over the clouded sky.
According to the headnote, these are twenty-three poems composed in grief by the attendants who served in Prince Kusakabe's palace. A left note, citing the Nihon shoki, records that the prince died in the fourth month of the third year of Empress Jitō's reign (689). The sequence takes up, scene by scene, the laments of the attendants: the garden and ponds of the Shima Palace bereft of their master, and the night watches they kept on the hills of Mayumi and Sada where the prince lay in state. This is the eighteenth poem of the sequence.
The authors were the attendants who served in Prince Kusakabe's palace, and their individual names have not come down to us. Toneri were officials who served close to the Emperor and members of the imperial family as guards and aides. One theory holds that Kakinomoto no Hitomaro composed the poems in the attendants' voice, but this is not settled.

The first line, "asagumori," means the sky being overcast from the morning.
The second line, "hi no iriyukeba," means "as the sun goes into the clouds," taken to suggest the death of the prince, child of the sun.
The third line, "mitatashi no," means "where he used to stand," the same word as in the eighth poem, 178, and others.
The fourth line, "shima ni oriite," means "going down into the garden and sitting."
In the final line, "nagekitsuru kamo," tsuru is the attributive of the perfective tsu and kamo is exclamatory: so I grieved.
