Ōbune no tsumori ga ura ni noramu to wa masashi ni shirite waga futari neshi

大船の津守が占に告らむとは
まさしに知りて我がふたり寝し

Roma-ji: Ōbune no tsumori ga ura ni noramu to wa masashi ni shirite waga futari neshi
English Translation: That in the reading
of Tsumori, harbor-keeper
for the great ships,
it would be told, I knew full well
when the two of us lay down.
Meaning: I knew full well that Tsumori's divination would reveal it, and still the two of us lay together.
Commentary: Book Two Love Poems 109

Headnote: "A poem composed by Prince Ōtsu when he secretly married Lady Ishikawa and Tsumori no Muraji Tōru exposed the matter by divination"
When his secret affair was exposed by Tsumori no Tōru's divination, the prince boldly declares that he lay with her fully aware that this would happen.
According to the headnote, when Prince Ōtsu secretly married Lady Ishikawa, Tsumori no Muraji Tōru uncovered the matter through divination, and the prince composed this poem. At the end of the headnote there is a note reading "details unknown."
The author, Prince Ōtsu, was a son of Emperor Tenmu; his mother was Princess Ōta, a daughter of Emperor Tenji. He was renowned for both learning and martial skill, but after Emperor Tenmu's death he was ordered to take his own life on a charge of treason.

The first line, "ōbune no," is a pillow word for tsu, "harbor," where great ships anchor. Poem 122 by Prince Yuge in this book begins with the same line.
In the second line, "tsumori ga ura ni," Tsumori refers to Tsumori no Muraji Tōru, who was skilled in the arts of divination.
In the third line, "noramu to wa," noru means to be revealed in a divination, and mu is conjecture.
The fourth line, "masashi ni shirite," means "knowing for certain," showing he was ready for the exposure.
In the final line, "waga futari neshi," shi is the attributive of the past auxiliary ki, closing with a lingering resonance.
