Imasara ni yuki furame ya mo kagiroi no moyuru harue to narinishi mono o

今さらに雪降らめやもかぎろひの
燃ゆる春へとなりにしものを

Roma-ji: Imasara ni yuki furame ya mo kagiroi no moyuru harue to narinishi mono o
English Translation: Now, at this late time,
could the snow come falling down?
For the heat-haze now
shimmers, blazing, as the spring
has come upon us at last.
Meaning: Could snow still fall now? Surely not—for spring has come, when the heat haze shimmers and blazes up from the earth.
Commentary: Book Ten Spring Miscellaneous Poems 1835

Headnote continued from the preceding poem: "On Snow"
This poem insists that snow can no longer fall now that spring has come, with heat haze blazing up from the ground. Within the snow group it sings of snow only to deny it, and the heart that longed for spring shows all the more strongly. Whereas 1832 and 1834 sing of snow that keeps falling even in spring, this poem argues from the opposite side that snow should not fall now that spring is here, standing in contrast with them.

The first line, "imasara ni," means now at this point. It treats spring's arrival as given and makes snowfall seem out of place.
In the second line, "yuki furame ya mo," "me ya mo" is rhetorical: would snow fall? surely not. The poem breaks after this line.
The third line, "kagiroi no," means of the heat haze and leads into "moyu," to blaze, presenting the haze shimmering in the spring sunlight.
In the fourth line, "moyuru harue to," "harue" means springtime, and the blazing haze vividly impresses the arrival of warm spring.
In the last line, "narinishi mono o," "mono o" is a conjunctive particle carrying both contrast and exclamation. By inversion it gives the reason and supports the rhetorical question of the second line.
