Ayuchigata shiohinikerashi chita no ura ni asa kogu fune mo oki ni yoru miyu

年魚市潟潮干にけらし知多の浦に
朝漕ぐ舟も沖に寄る見ゆ

Roma-ji: Ayuchigata shiohinikerashi chita no ura ni asa kogu fune mo oki ni yoru miyu
English Translation: At Ayuchi Bay
the tide must have ebbed away;
in Chita's inlet
even boats that row at dawn
I see drawing out to sea
Meaning: The tide must have ebbed at Ayuchi Flats—I see even the boats rowing out at dawn from Chita Bay keeping far offshore.
Commentary: Book Seven Miscellaneous Poems 1163

Headnote continued from the preceding poem: "Composed on Journeys"
Seeing boats rowing at dawn in Chita Bay move out toward the open sea, the poet infers that the tide must have ebbed at Ayuchi Flats. It is an observant landscape poem that reads the ebb tide from the movement of boats.
It is one of the poems composed on journeys. Ayuchi Flats were tidal flats in the sea of Owari, thought to lie in the south of present-day Nagoya. The phrase "the tide must have ebbed at Ayuchi" also appears in poem 271 in Book Three, by Takechi no Kurohito. The poet is unknown.

The first line names the tidal flats of Owari.
In the second line, "kerashi" is a contraction of "keru rashi," inferring something that has already happened. The poem pauses here; the same phrase appears in poem 271 in Book Three.
The third line, "in Chita's inlet," refers to the shore of the Chita Peninsula and has an extra syllable.
The fourth line, "even boats that row at dawn," refers to boats out in the morning.
The final line, "I see drawing out to sea," gives the evidence for the inference in the second line.
