lifts its voice in song, today
on Kasuga Plain,
the deep snow of this outing
I take to be the blossoms.

Commentary: Book Sixteen Miscellaneous Spring Poems 1044

Headnote: "From among the many poems presented by the provincial governor when the Kyōgoku Consort made a pilgrimage to Kasuga"
The poet says that as the bush warbler sings, he sees the deep snow falling on today's outing at Kasugano as blossoms. The headnote shows it is one of the many poems presented by the provincial governor when the Kyōgoku Consort made a pilgrimage to the Kasuga Shrine. Pivoting "miyuki" on a noble "outing" and "deep snow," it celebrates the pilgrimage amid falling snow as blossoms in full bloom, together with the warbler's song.
The three poems from 1044 to 1046 are taken from the poems presented by the governor of Yamato when the Kyōgoku Consort made a pilgrimage to the Kasuga Shrine.
The author, Fujiwara no Tadafusa, was of the Kyōke branch of the Fujiwara and held posts such as Governor of Yamato. He excelled in music and is said to have composed the gagaku piece "Kochō." The Kyōgoku Consort was Hōshi, a daughter of Fujiwara no Tokihira, who enjoyed the favor of Retired Emperor Uda.

First line, "uguisu no," means "the bush warbler."
Second line, "nakitsuru nae ni," means "even as it sang," with "tsuru" the attributive form of the perfective "tsu" and "nae ni" meaning "together with."
Third line, "Kasugano no," means "of Kasugano" in Yamato, and the next two poems also sing of Kasugano.
Fourth line, "kyō no miyuki o," means "today's outing," with "miyuki" a pivot word on a noble's "outing" and "deep snow." It uses the same pivot as the second line of 1026 in this book, "kakaru miyuki wa."
Final line, "hana to koso mire," means "I see as blossoms," with the binding particle "koso" resolved by the perfective form "mire."
