峰にぞ月はむねと澄みける

as the showers clear away,
on Azumaya's
peak the moon shines brightest,
clear above the ridgepole there.
Meaning: In the tenth month, as the showers cleared, it was on the peak of Azumaya above all that the moon shone clear, as if upon its ridgepole.

Headnote: "At a place called Azumaya, seeing the moon after the showers"
Composed at Azumaya in Ōmine, seeing the moon after the early winter showers. With the tenth-month showers cleared, the moon shone clearest of all upon the peak of Azumaya.
Taking the place name Azumaya as a pavilion, the poem wittily pivots on mune, the "ridgepole" of such a building and mune to, "above all." The purity of the moon after the showers stands out over the peak. The poem pairs with the next under the same headnote.

First line, “Kannazuki”: the tenth lunar month, the season of showers.
Second line, “shigure harureba”: as the showers cleared; the realis with ba gives a definite condition.
Third line, “azumaya no”: a place in Ōmine, echoing an open pavilion, associated with "ridgepole."
Fourth line, “mine ni zo tsuki wa”: zo is emphatic, answered by the attributive keru in the fifth line.
Fifth line, “mune to sumikeru”: mune pivots on the "ridgepole" of the pavilion and mune to, "chiefly, above all."
