Fudoki

Fudoki (風土記?) are ancient records of provincial culture, geography, and oral tradition presented to reigning monarchs of Japan. They contain agricultural, geographical, historical and mythological records, as well as folklore. Fudoki manuscripts also document local myths, rituals, and poems that are not mentioned in the Kojiki and the Nihon Shoki chronicles, which are the most important literature of the ancient national mythology and history. In the course of national unification, the imperial court enacted a series of criminal and administrative codes called ritsuryō and surveyed the provinces established by such laws to exert greater control over them.
