Editing Nihon Shoki (section)

===Sources===
The {{Lang|ja-latn|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 {{Lang|ja-latn|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]] in July 645.

The work's contributors refer to various sources which do not exist today. Among those sources, three [[Baekje]] documents (''Kudara-ki'', etc.) are cited mainly for the purpose of recording diplomatic affairs.<ref>[https://books.google.com/books?id=7jDuhnI6r9UC&q=paekche+nihon&pg=PA40 Sakamoto, Tarō.

Some other sources are cited anonymously as ''aru fumi'' ({{lang|ja-Hani|一書}}; "some document"), in order to keep alternative records for specific incidents.
