From that point onward, official histories were written in chronological order, but beginning with Shoku Nihongi (Chronicles of Japan, Continued), a unique new style emerged in which the history, although at its fundamental level still written chronologically, also included accounts of the deaths of famous people as well as simple biographies; this style was termed "Kokushitai" (Japanese-style chronological history).
それ以後続けて編年体の正史が作られたが、続日本紀以後は、編年体を基本としながらも人物の薨去記事に簡単な伝記を付載する「国史体」とよばれる独自のスタイルが確立した。
