磯による波に心のあらはれて
寝覚めがちなる苫屋形かな

Roma-ji: Iso ni yoru nami ni kokoro no arawarete nezamegachi naru tomayakata kana
English Translation: By the waves that come
to the rocky shore, the heart
is washed and laid bare—
so often waking from sleep
beneath the rush-mat roof.
Meaning: Washed by the waves that roll onto the rocky shore, the heart is laid bare, and one wakes so often in the night beneath the rush-mat roof.
Commentary: Miscellaneous Poems 1166

Headnote: "In the same painting, on the scene of a child startled awake under the rush mats"
On the same screen, a child has woken with a start under a rush-mat roof. Washed by the sound of waves rolling onto the rocks, and startled into wakefulness, the child wakes often beneath the rush matting, the poet says.
Finding the reason for the child's waking in the sound of the waves, the poem gives the scene a story. Arawarete pivots on "washed" and "revealed," and the poem is built on wave imagery.

First line, “iso ni yoru”: rolling onto the rocky shore.
Second line, “nami ni kokoro no”: the heart, by the waves.
Third line, “arawarete”: pivots on the heart "washed" by the waves and the startle "revealed."
Fourth line, “nezamegachi naru”: apt to wake in the night.
Fifth line, “tomayakata kana”: tomayakata is a cabin roofed with rush mats, on a boat or a hut; kana is exclamatory.
