Sashikitsuru mado no irihi o aratamete hikari o kauru yūzukuyo kana

さし来つる窓の入日をあらためて
光をかふる夕月夜かな

Roma-ji: Sashikitsuru mado no irihi o aratamete hikari o kauru yūzukuyo kana
English Translation: The setting sun's rays
that came slanting through my window
it now renews,
changing light for light again—
the moon on an early evening.
Meaning: Taking over from the setting sun that had been shining through my window, the evening moon renews the light, exchanging one radiance for another.
Commentary: Miscellaneous Poems 1153

Headnote: "As the light of the setting sun faded, the moon shone into my window"
Composed as the setting sun's light faded and the moon shone in at the window. Replacing the sunset light that had come through the window, the evening moon renews the light.
The poem catches the instant when the light at the window changes from sun to moon; the quiet passage of time as the setting sun gives way to the evening moon is concentrated at a single window.

First line, “sashikitsuru”: that had been shining in; tsuru is the attributive of the perfective.
Second line, “mado no irihi o”: the setting sun at the window.
Third line, “aratamete”: renewing, afresh.
Fourth line, “hikari o kauru”: exchanging the light, sunlight for moonlight.
Fifth line, “yūzukuyo kana”: yūzukuyo is the evening moon; kana is exclamatory.
