Shoku Nihon Kouki - Shoku Nihon Kouki

This is an imperially commissioned history book following the Nihon Koki. It has 20 volumes and is the fourth of the Six National Histories. It covers the 18 years from Emperor Ninmyo's accession to the throne in 833 (Tencho 10) to his death and funeral in 850 (Kasho 3). In 855 (Saihō 2), by order of Emperor Montoku, five men - Fujiwara no Yoshifusa, Fujiwara no Yoshimi, Tomo no Yoshio, Haruzumi no Yoshitada, and Agata Inukai no Sadamori - edited it, and it was completed and presented in 869 (Jogan 11) during the reign of Emperor Seiwa. During this time, Yoshiakira died of an illness, Yoshio was exiled to Izu due to the Otenmon Incident, and Sadamori was appointed as the governor of Suruga Province and was appointed to his post, so Yoshifusa and Yoshinawa, who remained behind, reported the incident. Whereas previous national histories have dealt with the reigns of several or even several decades of emperors, this book is distinctive in that it covers the reign of Emperor Ninmyo alone, and the articles are detailed. Among the ancient manuscripts is a copy formerly owned by Takayanagi Mitsutoshi that was copied from a copy from 1136 (Hōen 2), of which two volumes, volumes 5 and 8, remain. In addition, there is a copy from the Sanjōnishi family lineage that was copied in the Muromachi period, but there are many errors, missing sentences, and omissions. Included in the Kokushi Taikei.

『日本後紀』に続く勅撰(ちょくせん)の歴史書。20巻。「六国史(りっこくし)」の4番目。833年（天長10）の仁明(にんみょう)天皇の即位より850年（嘉祥3）の仁明の死去と葬儀に至る18年の歴史を記す。855年（斉衡2）文徳(もんとく)天皇の命により藤原良房(よしふさ)、藤原良相(よしみ)、伴善男(とものよしお)、春澄善縄(はるずみのよしただ)、県犬養貞守(あがたいぬかいのさだもり)の5人が編集にあたり、清和(せいわ)天皇の869年（貞観11）に完成・奏上した。この間、良相は病死、善男は応天門(おうてんもん)の変によって伊豆に流され、貞守は駿河守(するがのかみ)となって赴任したため、残った良房、善縄によって奏上された。これまでの国史は数代から数十代の天皇の時代のことを扱っているのに対し、本書は仁明天皇一代を対象とする点が特色で、記事も詳しい。古写本には1136年（保延2）の写本を影写した高柳光寿(みつとし)旧蔵本があり、巻5、巻8の2巻が現存する。そのほかに室町時代書写の三条西(さんじょうにし)家本系統の写本があるが、錯簡、脱文、省略が多い。『国史大系』所収。
