割れて入りぬる山の遠方

where the blossom is carried
the crescent has split
and gone down out of the sky
beyond the far mountainside

I might have watched the shallows carrying the blossom away; but the crescent has broken and gone down beyond the far hills.
Commentary
Book Two Spring Poems II 152

Headnote: composed on the line about the moon setting and the blossom-strewn shallows growing dark, when Ki no Tsurayuki held a winding-water banquet.
The second poem on the winding-water banquet. The topic is a line of Chinese verse rendered into Japanese; Oe no Chisato's fifty-fifth poem in Book One is another such piece.
Sakanoue no Korenori was an early Heian poet, counted among the thirty-six immortals of poetry.
The time is the night of the third day of the third month; the place is beside shallows carrying blossom.
The occasion was the banquet held by Ki no Tsurayuki.

The first line names shallows carrying petals away, answering to the blossom-strewn shallows of the topic.
The auxiliary in the second line expresses possibility: shallows one might have seen. The implication is that with a moon they would have been visible.
The third line brings in a crescent, thin and weak in light.
The verb in the fourth line, to split, answers to the crescent's shape, turning the form into an action; the verb after it means the setting of the moon, answering to the topic's moon-setting.
The poem closes on a noun meaning a place far off. The moon sinks behind the hills and the blossom-carrying water is lost. The darkness of the topic is never named; only the setting of the moon is given. The Chinese line is divided into three elements and distributed across the five lines with some dexterity.
