Keigo Seki

was a Japanese folklorist. He joined a group under Yanagita Kunio, but often came to different conclusions regarding the same folktales. Along with collecting and compiling folktales, Seki also arranged them into a series of categories.

A selection was published as Nihon No Mukashi-Banashi (1956–7), and was translated into English as Folktales of Japan (1963) by Robert J. Adams. Seki also thought that there was a universal element to folktales and that they are not based on particular ethnic groups.
