The, also called the,[1] [2] [3] is a privately compiled anthology of waka and kanshi compiled between 893 and 913.
The work is in two volumes, the first having been compiled in 893 and the second being added in 913.[1] [2] [3] Its compilation is traditionally attributed to the great scholar and kanshi poet Sugawara no Michizane, but other theories have been proposed.[1] [2] The attribution was first made in the eleventh century, and is today accepted by most scholars.[4] Even if Michizane wrote the poetry himself, he could not have composed the preface to the second volume, which is dated 913, ten years after Michizane's death.[4]
The text consists of alternating waka and kanshi on the same theme. The waka are written in Man'yōgana, similarly to the Man'yōshū.
