昨日の雲の跡の山風

Whose promise was it, that now
ends in this at last?
Where yesterday's clouds have been
now only the mountain wind.
Meaning: Remember, please: whose promise has come to this end? Where yesterday's clouds once hung, only the mountain wind now blows.
Commentary: Book Fourteen Love Poems IV 1294

Headnote: "For the Poetry Contest in Fifteen Hundred Rounds."
This is the fourth poem of the sequence on love being forgotten. Remember, the speaker says: whose promise has it come to, this mountain wind blowing where yesterday's clouds have gone? According to the headnote, it was submitted to the Poetry Contest in Fifteen Hundred Rounds.
The author, "Ietaka, Lord of the Court," is Fujiwara no Ietaka. A son of Fujiwara no Mitsutaka, he studied poetry under Fujiwara no Shunzei and became one of the compilers of the Shinkokinshū. He later reached the Junior Second Rank and was called the Mibu Second Rank.
The Poetry Contest in Fifteen Hundred Rounds, the largest in history, was arranged by Retired Emperor Go-Toba, who in Kennin 1 (1201) had thirty poets each compose a hundred-poem sequence and over the following year had the poems matched in fifteen hundred rounds and judged.

The first line, "omoiide yo," is an imperative, "remember," with six syllables, one more than the norm, and the poem breaks after it.
In the second line, "ta ga kanegoto no," "kanegoto" is a promise made beforehand. By asking "whose," the speaker reminds the other that the promise was their own.
The third line, "sue naramu," means "is this where it has ended?" The poem breaks after this line.
The fourth line, "kinō no kumo no," means "of the clouds that were there until yesterday." Taking up "sora no kumo" in the preceding poem, it overlays the departed clouds with the departed lover.
The last line, "ato no yamakaze," ends on a noun. It presents the mountain wind blowing where the clouds have gone as what remains at the end of the promise, entrusting emptiness to the scene.
