This manuscript, known as the Hirosawa edition, is a segment from a collection of poems written by Emperor Fushimi (1265-1317). Originally thought to be a collection of one hundred poems on the four seasons, love, and miscellaneous themes, today only fifty-five poems exist. Inscribed on scrap paper that was originally used for documents and with traces of revisions, this collection was meant to be a draft. Included among the fifty-five poems appear to be poetic works by the poet Saionji Sanekane, who was the emperor's attendant. Moreover, the brush style and the black margin lines resemble the segments from the one hundred poems by Sanekane (known as the Nonomiya edition) that are pasted into the poem anthology Moshiogusa (National Treasure, Kyoto National Museum), making it highly likely that this manuscript was part of a poem draft by Sanekane.
