Obasute wa shinano naranedo izuku ni mo tsuki sumu mine no na ni koso arikere

姨捨は信濃ならねどいづくにも
月澄む峰の名にこそありけれ

Roma-ji: Obasute wa shinano naranedo izuku ni mo tsuki sumu mine no na ni koso arikere
English Translation: Obasute, it seems,
need not be in Shinano—
wherever it may be,
it's the name of a peak
where the moon shines bright and clear.
Meaning: So Obasute need not be in Shinano: wherever it may be, it is the name of a peak where the moon shines clear.
Commentary: Miscellaneous Poems 1107

Headnote: "A place called Obasute Peak came into view, and perhaps because of what I thought, the moon looked especially fine"
Within the Ōmine range was a peak called Obasute, and as it came into view the moon seemed especially beautiful, perhaps because of the name. Obasute, the poet says, is not only the mountain in Shinano; wherever it is, it is the name of a peak where the moon shines clear.
Mount Obasute in Shinano was a famous poetic place for the moon ever since the Kokinshū poem "Waga kokoro nagusamekanetsu Sarashina ya Obasuteyama ni teru tsuki o mite." Finding the moon especially fine at a peak of the same name in Ōmine, he playfully concludes that the name itself means a peak where the moon is clear.

First line, “Obasute wa”: the name Obasute, set forth.
Second line, “shinano naranedo”: do is concessive, "though not in Shinano."
Third line, “izuku ni mo”: wherever it may be.
Fourth line, “tsuki sumu mine no”: of a peak where the moon is clear.
Fifth line, “na ni koso arikere”: koso is emphatic, answered by the realis kere; keri marks realization.
