Chōshūki - Chōshūki

The diary of Minamoto no Morotoki (1077-1136), who was a provisional middle counselor and provisional chief minister of the empress's palace. The name "Choshuuki" comes from the Chinese name for the empress's palace, Choshukyu, and is also called "Gondaifu-ki" or "Morotoki-ki" or "Mizu Nikki" (Water Diary) after the radicals of the characters "Minamoto" and "Toki" in his name. It is said that there were originally nearly 70 volumes in the 50 years from 1087 (Kanji 1) to 1136 (Hōen 2), but many volumes are missing, and there are only about 13 volumes from 1111 (Ten'ei 2). Morotoki was well versed in court etiquette and customs, and was also an uncle of Emperor Toba's empress, Bifukumon'in (Tokushi), so he was well versed in the intricacies of the imperial court. For this reason, "Choshuuki" is an indispensable document for learning about politics and court ceremonies, and also contains articles related to Buddhism and social conditions. It is a valuable historical resource for learning about trends during the Insei period. It is collected in two volumes in "Shiryo Taisei."

権中納言(ごんちゅうなごん)兼皇后宮権大夫(ごんだいぶ)源師時(もろとき)（1077―1136）の日記。『長秋記』の名は皇后宮の唐名である長秋宮にちなんだもので、ほかに『権大夫記』『師時記』、さらには姓名の一部の「源」と「時」の偏をとって『水日記』ともいう。もとは1087年（寛治1）から1136年（保延2）まで50年間にわたって70巻近くあったというが、いまは欠巻も多く、1111年（天永2）からの13巻ほどである。師時は有職故実(ゆうそくこじつ)に明るく、鳥羽(とば)天皇の皇后美福門院(びふくもんいん)（得子）の伯父にあたることもあって宮廷の機微にも通じていた。その意味からも『長秋記』は政治、朝儀典礼を知るために欠くことのできない文献で、そのほか仏教関係、世相風俗の記事もまま見受けられる。院政期の動向を知る貴重な史料である。『史料大成』に二冊本で所収。
