the one my love made for me,
I see is soiled with grime

My journey must have grown long, I think, when I see the grime upon this robe my wife gave me, the one I am wearing.
Commentary
Book Fifteen Poems of the Envoys to Silla 3667

Headnote continued from the preceding poem: "Nine poems composed while gazing at the moon by the sea"
Seeing the grime on the robe his wife made ready for him, he realizes how long his journey has grown. He feels the passing of the days through something as close at hand as a soiled robe. Set against the robe from his wife's hands longed for in the preceding poem, the robe he has worn throughout the long journey tells of the length of time he has been apart from her.
According to the headnote, this is one of nine poems composed while gazing at the moon by the sea, thought to have been made during the stay at the Tsukushi lodge. The author of this poem is not named.

First line, "waga tabi wa": my journey.
Second line, "hisashiku arashi": "rashi" is an auxiliary of grounded inference: it seems to have grown long. The poem breaks after the second line.
Third line, "kono a ga keru": "keru" is regarded as the verb for wearing with the continuative auxiliary "ri": which I am now wearing. A six-syllable hypermetric line.
Fourth line, "imo ga koromo no": the robe my wife made ready and sent with me.
Fifth line, "aka tsuku mireba": when I see the grime upon it; by inversion it gives at the end the ground for the inference in the second line.
