keep me in your heart, I say,
as I send to you
this keepsake of mine;
do not show it to others
Meaning: This keepsake I send you, asking you to keep me in your heart as one hangs a mirror: do not show it to anyone else.
Commentary: Book Fifteen Exchange Poems of Nakatomi no Yakamori and Sano no Otogami no Otome 3765

Headnote continued from the preceding poem: "Poems exchanged between Nakatomi no Ason Yakamori and Sano no Otogami no Otome"
He asks the young woman not to show others the keepsake he sends her to keep him in her heart. Their relationship was one that shunned others' eyes, and he fears that showing the keepsake would give rise to gossip. Whereas the young woman sent a robe as a keepsake in 3753, here Yakamori sends one from his side, suggesting a relationship in which they exchanged keepsakes.
The author, Nakatomi no Yakamori, was a son of Nakatomi no Azumahito, from the Nakatomi clan in charge of the rites of the gods. He was exiled to Echizen Province for an offense, but was later pardoned and returned to the capital.
A left note reads "the above thirteen poems are by Nakatomi no Ason Yakamori"; the thirteen poems from 3754 to 3766 of this book were sent by Yakamori to the young woman from his place of exile. The latter half of this book contains sixty-three poems exchanged between Nakatomi no Yakamori and Sano no Otogami no Otome. According to the book's table of contents, when Yakamori took as his wife the young woman, a lady-in-waiting of the palace storehouse office, he was exiled to Echizen Province by imperial decree. The place of exile is thought to be Ajimano in Echizen, near present-day Echizen City, Fukui Prefecture.

Third line, "matsuridasu": a humble verb meaning to present, to offer.
Fourth line, "katami no mono o": an object that serves as a keepsake of someone far away.
Fifth line, "hito ni shimesu na": "na" is prohibitive: do not show it to others, the poem ends.
