In 713 the court ordered every province to submit a report: the products of the land, the fertility of the soil graded, the origins of the names of mountains, rivers and plains, and the old traditions transmitted by elders. Only the Izumo Fudoki survives substantially complete, submitted in 733, with significant fragments of Hitachi, Harima, Bungo and Hizen and quotations from others. Its value is that it is a provincial voice: the Izumo report tells the kunibiki story, in which the deity pulls surplus land from Korea and the Noto peninsula across the sea with ropes to enlarge Izumo, and it names local kami and shrines that the Kojiki and Nihon Shoki either omit or subordinate. Set beside the court chronicles, the Fudoki show that the neat genealogy of kami in the Kojiki is a centralising edit imposed on a much more scattered and local set of traditions. Modern folklore studies in Japan, from Yanagita Kunio onward, have leaned heavily on this material and on its living descendants.
