classic waka stream

Is it spring rain
that softly falls—or tears,
for cherry blossoms,
since there is no one
who does not grieve their scattering?

Meaning
Is the softly falling spring rain perhaps tears? For there is no one who does not grieve the scattering of cherry blossoms.
Commentary
Book II, Spring Poems (Part Two)

The poem likens spring rain to the tears of those who lament the falling of cherry blossoms; or perhaps, because the spring rain scatters the blossoms, people are moved to tears.

In another text, it is said to have been composed at a poetry contest held at the residence of the Ninna Middle Captain’s consort.
