ABSTRACT
The main genealogy of Enchin Keizu can be divided into three parts. In Part A, Emperor Keikō and his children, a total of twenty-four princes and princesses, are recorded. Part B is the genealogy of the Iyo-no-Mimurawake-no-Kimi clan. Part C is the genealogy of the Inagi-no-Obito clan. Nobutomo Ban and Kumema Ōkura were the first people to study Enchin Keizu. Takashi Tanaka investigated the original manuscript and reprinted it. Arikiyo Saeki and Akiko Yoshie began to study the genealogy in detail. Hironobu Matsubara and Kenkichi Katō mentioned this genealogy in the study of clans that inhabited Iyo Province and Sanuki Province. Enchin Keizu is not available to investigate easily because it is designated as one of the national treasures of Japan. This chapter examines a collotyped reproduction with full-scale photographs and historical photographs of Enchin Keizu.
