Ama no hara kumo naki yoi ni nubatama no yo wataru tsuki no iramaku oshi mo

天の原雲なき宵にぬばたまの
夜渡る月の入らまく惜しも

Roma-ji: Ama no hara kumo naki yoi ni nubatama no yo wataru tsuki no iramaku oshi mo
English Translation: In the plain of heaven,
on an evening without clouds,
black as jewel-seed,
the moon that crosses through the night—
how I grieve to see it set.
Meaning: On an evening when not a cloud is in the wide sky, how I regret that the moon crossing the night will soon sink out of sight.
Commentary: Book Nine Miscellaneous Poems 1712

Headnote: "A poem on the moon, composed on climbing Mount Tsukuba"
The poet regrets that the moon crossing a cloudless evening sky will soon sink behind the hills. One feels the wide, clear night sky seen from the summit of Mount Tsukuba.
The headnote says the poem was composed on the moon after climbing Mount Tsukuba, but gives no author. Mount Tsukuba stands in present-day Tsukuba, Ibaraki. Like "to see it hide, how I regret" at the end of 1691, it closes with regret for the setting moon.

The first line, "in the plain of heaven," means the vast open sky.
The second line, "on an evening without clouds," sets the clear sky that makes the moon so precious.
The third line, nubatama no, is a pillow word for night, as also in the first line of 1706.
The fourth line, "the moon that crosses through the night," describes the moon moving across the sky.
The final line, "how I grieve to see it set," uses iramaku, a nominalized form of iru, "to set." It takes the same form as kakuraku oshi mo in 1691.
