Commentary
Book Fifteen Poems of the Envoys to Silla 3682

Headnote continued from the preceding poem: "Seven poems composed on the night the ship anchored at Komashima Lodge in Matsura District, Hizen Province, each man gazing far over the waves and grieving in his traveling heart"
A woman's poem calling to a departing traveler: she will wait, praying to the gods of heaven and earth; may he come back soon, for waiting is painful. A left note reads "the above poem is by a young woman," attributing it to a local woman who received the embassy at Komashima. It is thought to be a poem by a wandering woman entertainer who attended the banquet and entertained the travelers, consoling the travelers' longing as if singing on behalf of the wives waiting in the capital.
The author is recorded in the left note only as "a young woman," and her name has not come down.
According to the headnote, this is one of seven poems composed on the night the ship anchored at Komashima Lodge in Matsura District, Hizen Province, each gazing far over the waves and expressing the grief of travel. Komashima is thought to be Kashiwajima Island in present-day Karatsu, Saga Prefecture, a harbor before the crossing to Iki.

First line, "ametsuchi no": the gods of heaven and earth, meaning all the gods.
Second line, "kami o koitsutsu": "kou" means to pray and entreat the gods, and "tsutsu" is continuative: praying to the gods.
Third line, "are matamu": "mu" is an auxiliary of intention: I shall wait. The poem breaks after the third line.
Fourth line, "haya kimase kimi": "mase" is an honorific imperative: come soon, my lord, she calls.
Fifth line, "mataba kurushi mo": "mataba" is a hypothetical condition and "mo" exclamatory: for waiting is painful, adding the reason for the wish in the fourth line.
