Commentary: Book Five Autumn Poems II 363

Headnote continued from the preceding poem: "Composed on the topic 'Falling Leaves on the Road Through the Barrier' at the courtiers' poetry contest at the Hōjūji Palace in the second year of Kaō"
The poet likens the cold wind passing over Mount Ōsaka, scattering autumn leaves that pile up at the barrier, to a traveler who offers autumn leaves to the god of the barrier and passes on. It is a conceit that personifies the cold wind as a traveler crossing the barrier and sees the fallen leaves as an offering to the god.
The author, "Gon-Chūnagon Sanemori," was the son of Minister of the Right Fujiwara no Kin'yoshi, and rose to Provisional Middle Counselor.
Composed on the topic "Falling Leaves on the Road Through the Barrier" at the courtiers' poetry contest held in the second year of Kaō (1170) at the Hōjūji Palace of Retired Emperor Go-Shirakawa. It is the third of a run of five poems, 361 through 365, on this topic, which sing of barriers in many places: Suma, Kiyomigata, Ōsaka and Shirakawa.
Ever since Sugawara no Michizane's Kokin Wakashū poem, "This time I could bring no offering; at Tamuke Mountain, take this brocade of autumn leaves, as the gods will," the conceit of offering autumn leaves to the gods had been sung.

First line, "momijiba o": naming the offering.
Second line, "seki moru kami ni": "seki moru" is to guard a barrier, here the god enshrined at the Ōsaka barrier. Where the "sekimori" of 361 of this book was a man, this poem sings of the god who guards the barrier.
Third line, "tamukeokite": "tamuku" is to make an offering to the gods, and "oku" means "leaving it there."
Fourth line, "Ōsakayama o": Mount Ōsaka, on the border of Yamashiro and Ōmi, where the Ōsaka barrier stood.
Fifth line, "suguru kogarashi": the poem ends on a noun, likening the cold wind to a traveler passing through the barrier.
