Tsukubane no iwa mo todoro ni otsuru mizu yo ni mo tayura ni waga omowanaku ni

筑波嶺の岩もとどろに落つる水
よにもたゆらに我が思はなくに

Roma-ji: Tsukubane no iwa mo todoro ni otsuru mizu yo ni mo tayura ni waga omowanaku ni
English Translation: On Mount Tsukuba
waters fall so the boulders
ring and roar with them:
never in such wavering wise
do I think of you, my love.
Meaning: Like the water that plunges so the very rocks of Mount Tsukuba roar, my love for you is never shallow or wavering.
Commentary: Book Fourteen Azuma Poems 3392

Headnote continued from the preceding poem: "Sōmon (Love Exchanges)"
Like the violent water that crashes roaring onto the rocks of Tsukuba, the singer insists that his love is never wavering or idle. The force of the torrent is laid over the earnestness of his feeling.
It is one of the Hitachi poems. Its second half closely resembles that of 3368 from Sagami, "yo ni mo tayora ni koro ga iwanaku ni," showing the same turn of phrase in use in different provinces.
The poet is unknown. The Azuma uta are thought to have been sung among the people of the eastern provinces, and they are marked by plain, open-hearted expression mixed with local dialect.

First line, "tsukubane no": Mount Tsukuba, as the Hitachi poems on the mountain continue.
Second line, "iwa mo todoro ni": "Todoro ni" describes a roaring, the sound of water crashing on rock.
Third line, "otsuru mizu": Plunging water; the first three lines form a preface leading by contrast to "tayura."
Fourth line, "yo ni mo tayura ni": "Tayura" means swaying and unsettled, the same word as "tayora" in 3368.
Final line, "waga omowanaku ni": "Naku ni" is an exclamatory negative: I do not think of you so.
