Uguisu no haru ni narurashi kasugayama kasumi tanabiku yome ni miredomo

鴬の春になるらし春日山
霞たなびく夜目に見れども

Roma-ji: Uguisu no haru ni narurashi kasugayama kasumi tanabiku yome ni miredomo
English Translation: The warbler's springtime
has arrived now, so it seems;
Kasuga's mountain—
the haze is trailing along,
though I see it in the night.
Meaning: The warblers' spring seems to have arrived: over Mount Kasuga the haze is trailing—though I see it only by night.
Commentary: Book Ten Spring Miscellaneous Poems 1845

Headnote continued from the preceding poem: "On Haze"
Seeing haze trail over Mount Kasuga so clearly that it can be made out even at night, the poet infers that spring, the season of the warbler, has come, and this poem closes the haze group. It shows a delicate sensibility that catches haze within the dim field of night vision. Against the preceding poem's Mount Kasuga in the morning sun, this one sings of Mount Kasuga at night, depicting the same mountain's haze in a contrast of morning and night.

The first line, "the warbler's," qualifies "spring," meaning the spring when warblers sing. The bird that was the theme of the bird group is here used to describe the season.
In the second line, "haru ni narurashi," "rashi" marks grounded inference, and the poem breaks here, in the same inferential form as "haru kitarurashi" in the preceding poem.
The third line, "Mount Kasuga," names the mountain shared by all three haze poems, here set down as a noun.
The fourth line, "the haze trails," is the scene that grounds the inference, the same phrase as the last line of the preceding poem.
The last line, "though I see it by night," is hypermetric. By inversion it adds the dimness of night vision, showing the certainty that the haze can still be made out.
