Following the earlier national history Nihon Montoku Tennō Jitsuroku (879), Emperor Uda ordered the compilation of the years since then. It was compiled by Fujiwara no Tokihira, Sugawara no Michizane, Ōkura no Yoshiyuki, and Mimune no Masahira. The text was completed in 901.Contents
Written in Kanbun-style and contained within fifty volumes, the contents cover a span of thirty years from 858 to 887 corresponding to three imperial reigns: Seiwa, Yōzei, and Kōkō. It contains many imperial edicts and is more detailed compared to the earlier texts. Particularly famous is a description of Ariwara no Narihira. Parts of volumes 15, 19, and 48 are incomplete.
Also described is an earthquake in July 869 and a tsunami that flooded the plains of northeast Japan: “The sea soon rushed into the villages and towns, overwhelming a few hundred miles of land along the coast. There was scarcely any time for escape, though there were boats and the high ground just before them. In this way about 1,000 people were killed.” These were the same plains that were submerged in the 2011 Tōhoku earthquake and tsunami, according to one account. "Analysis of sediments left by the 869 tsunami led to an estimate that the earthquake had a magnitude of 8.3."
