Natsu fukami omoi mo kakenu utatane no yoru no koromo ni akikaze zo fuku

夏深み思ひもかけぬうたた寝の
夜の衣に秋風ぞ吹く

Roma-ji: Natsu fukami omoi mo kakenu utatane no yoru no koromo ni akikaze zo fuku
English Translation: Summer has grown deep,
and unlooked-for, while I doze
through a fitful sleep,
on the robes I wear at night
the autumn wind is blowing.
Meaning: Summer has grown so deep that, unexpectedly, the autumn wind blows upon the night robes in which I doze.
Commentary: Summer Poems 172

Headnote: "Night wind cools the robes"
Summer has deepened, and the poet finds an autumn wind unexpectedly blowing on the night robes in which he dozes. The poem conveys the surprise of feeling autumn's touch on the skin while still thinking it summer.
The Ruijū text gives the headnote as "On the theme 'Night wind chills the robes.'"

Line 1, natsu fukami, means "since summer has deepened," with mi on an adjective stem marking a reason. It takes up "the depth of summer" in the preceding poem, 171.
Line 2, "unlooked-for," shows how unexpected the autumn wind is.
Line 3 is the same word as the opening of 161.
Line 4 is also the same as line 2 of 161. There the scent of the tachibana reached the night robes; here the autumn wind blows on them, so summer's fragrance and autumn's wind come to the same night robes in corresponding poems.
Line 5 concludes the binding particle zo with the attributive fuku, presenting the topic "night wind cools the robes."
