About “Kujiki”
Kujiki, also known as Sendai Kuji Hongi, is a historical Japanese text. It was once considered one of the earliest Japanese histories, but during the Edo period, scholars like Tokugawa Mitsukuni and Tada Yoshitoshi argued that it was an imitation based on earlier works such as the Nihon Shoki, the Kojiki, and the Kogo Shūi. Most modern scholarship suggests that the Kujiki contains some authentic elements. Book 5 is thought to preserve traditions of the Mononobe and Owari clans, while Book 10 is believed to contain an earlier record known as the Kokuzō Hongi.
