蘇我馬子
The "Nihon Shoki" is a synthesis of older documents, specifically on the records that had been continuously kept in the Yamato court since the sixth century. It also includes documents and folklore submitted by clans serving the court. Prior to "Nihon Shoki", there were "Tennōki" and "Kokki" compiled by Prince Shōtoku and Soga no Umako, but as they were stored in Soga's residence, they were burned at the time of the Isshi Incident.
