誰が谷か明日は残さん山桜
こぼれて匂へ今日の形見に

Roma-ji: Taga tani ka asu wa nokosamu yamazakura koborete nioe kyō no katami ni
English Translation: In whose valley, then
will any be left by dawn
you mountain cherries
spill down and glow while you can
as a keepsake of today
Meaning: Which valley will still have any tomorrow? Mountain cherries, spill and shine as you fall, and be the keepsake of this day.
Commentary: Book Two Spring Poems II 150

Headnote: composed on the day when the Ono-no-miya Chancellor viewed the blossom at Tsukinowa-dera.
On the day of a blossom-viewing, the poem grieves over the falling flowers and asks them to serve as a memento of the day. The Chancellor of the headnote is Fujiwara no Saneyori, known by his residence at Ono-no-miya; Tsukinowa-dera is a temple in the hills.
Kiyohara no Motosuke (908-990) was one of the thirty-six immortals of poetry and took part in compiling the Gosen Wakashu. He was the father of Sei Shonagon.
The time is when the cherries fall; the place is the hills around Tsukinowa-dera.
The occasion was his attendance at Saneyori's blossom-viewing.

An interrogative particle in the first line governs the auxiliary in the second: which valley? The assumption is that the flowers last differently from one valley to another.
The second line means: will keep any until tomorrow. The expectation is that by then there may be none.
The third line names the one addressed.
The fourth line is an imperative: spill and shine. The request is not that they should stay but that they should be beautiful in falling. Masatsune's hundred and forty-fifth poem asked the wind to let something glow a little longer; this one asks it of the flowers.
The word at the close names a thing kept in remembrance, used also in the hundred and forty-fourth poem. Grieving over the fall, the poem tries to keep the falling itself in memory.
