Commentary: Book Fifteen Poems of the Envoys to Silla 3710

Headnote continued from the preceding poem: "Eighteen poems composed while anchored at Takashiki Bay, each expressing his feelings"
He sings: when the tide goes out I will come again; come, let us go back, for the roar of the tide in the offing has risen high. It depicts withdrawing, driven by the rising tide, from the beach where he gathered shells in the preceding poem. A moment of everyday life on the journey is caught: lingering with regret yet yielding to the changes of the sea.
According to the headnote, this is one of eighteen poems composed while anchored at Takashiki Bay, each expressing his feelings. Takashiki Bay lies within Asō Bay in Tsushima, thought to be present-day Takeshiki in Mitsushima, Tsushima City, Nagasaki Prefecture. The last nine poems of the sequence have no left notes, and the author of this poem is not named.

First line, "shiohinaba": "na" is the irrealis of the perfective "nu": when the tide has gone out.
Second line, "mata mo ware komu": "mu" is intention: I will come again. The poem breaks after the second line.
Third line, "iza yukamu": "iza" is a word of invitation: come, let us go. The poem breaks here too, short phrases piled up expressing the movement of leaving.
Fourth line, "okitsu shiosai": "shiosai" is the sound of waves as the tide rises, the roar of the tide.
Fifth line, "takaku tachikinu": "nu" is perfective: it has risen high, giving at the end the reason for leaving.
