Commentary: Book Three Summer Poems 136

Headnote: "Composed on the topic 'Changing to Summer Robes' when presenting a hundred-poem sequence in the reign of Emperor Horikawa"
Composed on "Changing to Summer Robes" for the Horikawa Hundred-Poem Sequence, for which poets each presented one hundred poems in the reign of Emperor Horikawa. On the first day of the Fourth Month, when robes dyed in blossom colors are exchanged for summer garments, nothing remains any longer as a keepsake of the departed spring. Through the court custom of changing robes, the poem conveys the turn from spring to summer and a lingering regret for the lost season, and it opens the book of summer poems.
The author, "Former Middle Counselor Masafusa," is Ōe no Masafusa, son of Ōe no Narihira. As a scholar he served three emperors, Go-Sanjō, Shirakawa and Horikawa, rising to Provisional Middle Counselor. Famed for his learning, he was one of the poets of the Horikawa Hundred-Poem Sequence.
This poem and the next, 137, are both "Changing to Summer Robes" poems from the Horikawa Hundred-Poem Sequence, marking the start of summer through the change of clothing.

First line, "natsugoromo": light robes worn in summer, expressing the headnote's topic. Poem 219 of this book also opens with "natsugoromo."
Second line, "hana no tamoto ni": "hana no tamoto" are the sleeves of spring robes dyed in the colors of cherry and other blossoms. The book's final poem, 225, with "kaeru tamoto ni akikaze zo fuku," also speaks of sleeves, so the book begins and ends with sleeves, the start and close of summer answering each other.
Third line, "nugikaete": "taking off and changing," referring to the change of robes on the first day of the Fourth Month.
Fourth line, "haru no katami mo": a "katami" is a keepsake that recalls something gone. Poem 110 of Book Two, with "haru no katami ni," gathered violets as a keepsake of spring; here not even such a keepsake remains.
Fifth line, "tomarazarikeri": "zari" is the continuative of the negative "zu" and "keri" expresses realization, showing the poet newly aware that every trace of spring has vanished.
