Yorozuyo ni miru tomo akaji nagatsuki no ariake no tsuki no aramu kagiri wa

万代に見るとも飽かじ長月の
有明の月のあらむ限りは

Roma-ji: Yorozuyo ni miru tomo akaji nagatsuki no ariake no tsuki no aramu kagiri wa
English Translation: For ten thousand ages
though I gaze I shall not tire,
the long month's moon
lingering at break of day,
as long as it shines on.
Meaning: Though I gaze for ten thousand ages, I shall never tire of it, so long as the dawn moon of the long ninth month remains in the sky.
Commentary: Miscellaneous Poems 670

Headnote continued from the preceding poem: "A poem of felicitation"
The poet says he will never tire of the dawn moon of the ninth month though he gazes for ten thousand ages, as long as it remains in the sky, blessing an endless reign through the moon's beauty. Kamo no Mabuchi marked it with a sign of praise.
The Ruijū text places it in its section of celebration, with the special title "Celebration through the moon."

Line 1 means "for ten thousand ages."
Line 2 means "I shall not tire of seeing it," ji negative conjecture, with a break after the line.
Line 3 means "of the ninth month," naga echoing "lasting"; it takes up the autumn sky of the preceding poem.
Line 4 means "of the dawn moon."
Line 5 means "as long as it remains," in inversion; it pairs with "as long as they shine" at the end of the next poem, 671.
