Yakumo Misho

A book on waka poetry from the early Kamakura period. Written by Emperor Juntoku. Written before 1221 (Jokyu 3), it was revised and compiled in exile in Sado after the Jokyu War (1221). Six volumes. There are a rough draft version and a re-edited version, and the contents differ slightly. Volume 1 is the section on justice (explanations of the six principles, poetry style, poetry illnesses, etc.), volume 2 is the section on etiquette (collecting knowledge and records on the etiquette of poetry contests, poetry gatherings, and anthologies), volume 3 is the section on details (listing words and explaining 17 categories such as celestial phenomena and earthly phenomena), volume 4 is the section on language (explaining many words under three categories: secular language = ordinary words, historical language = historical words, and simplified language = difficult words), volume 5 is the section on famous places (listing the locations and sources of famous places), and volume 6 is the preparatory section (explanation of the author's theory on poetry). It is a masterpiece that is both a culmination of ancient poetry studies and the foundation of medieval poetry theory, and contains many quotations from books that have since been lost, making it an immensely valuable resource.

鎌倉初期の歌学書。順徳(じゅんとく)天皇の著作。1221年（承久3）より前から執筆、承久(じょうきゅう)の乱（1221）後、佐渡の配所で手を加えてまとめられた。六巻。草稿本と再撰(さいせん)本とがあり、内容も若干の相違がある。巻一は正義部（六義や歌体、歌病(かへい)などの解説）、巻二は作法部（歌合、歌会や撰集などの作法に関する知識、記録を集めたもの）、巻三は枝葉部（天象、地儀以下17部についてことばをあげ、解説を加えたりしたもの）、巻四は言語部（世俗言＝普通のことば、由緒言＝由緒あることば、料簡言＝難解なことばの三つをたてて多くのことばを解説）、巻五は名所部（名所の場所や出典を示したもの）、巻六は用意部（著者の歌論の披瀝(ひれき)）。古代歌学の集大成であるとともに中世歌論の基盤となった名著で、いまでは散逸した書からの引用も多く、資料的価値も絶大である。
