Roma-ji: Isonokami furu no kamusugi kamusaburu koi o mo are wa sara ni suru kamo
English Translation: Like the sacred cedars
of Furu in Isonokami,
aged and god-like grown,
a love in my later years
once again do I now feel
Meaning: Like the sacred cedars of Furu in Isonokami, grown old and god-like, I find myself once more in love in my advancing years.
Commentary: Book Eleven Love Poems Ancient and Modern I 2417

Headnote continued from the preceding poem: "Expressing Feelings through Things"
Though grown old like the ancient sacred cedars of the Isonokami Shrine, the speaker finds himself in love again, and he speaks as if surprised at himself. Comparing his aging self, still stirred by love, to the venerable cedar, he expresses it with a touch of embarrassment and lament.
This is one of the poems about gods, speaking through the sacred cedars at Furu. Like poem 2415 in this book, it names Furu; while 2415 speaks of love's long duration through the sacred fence, this one speaks of love in old age through the sacred cedar. The two use things from the same sacred precinct at Furu with different conceits.
The author is unknown; according to the left note, the poem comes from the Kakinomoto no Hitomaro Collection. That collection is thought to contain both Hitomaro's own poems and poems by others that he recorded. Kakinomoto no Hitomaro was a court poet active in the reigns of Empress Jito and Emperor Monmu, and is counted among the Thirty-Six Immortal Poets.

First line, "isonokami": the area of Isonokami in present-day Tenri, Nara Prefecture. "Isonokami" is also used as a pillow word attached to the place name Furu.
Second line, "furu no kamusugi": the sacred cedars of the Isonokami Shrine at Furu. The first two lines form a preface, and because the sacred cedars are aged and venerable, they lead into "kamusaburu" in the third line.
Third line, "kamusaburu": "grown old and venerable." While describing the sacred cedar, it also expresses the speaker's own age.
Fourth line, "koi o mo are wa": "even love, I." The particle "mo" shows surprise at finding oneself in love so unexpectedly.
Fifth line, "sara ni suru kamo": "do once again." "Sara ni" means anew, and the final particle "kamo" expresses wonder.
