This assertion of 'the legitimacy of the Emperor' and the 'uniqueness of Japan' were main themes in Rikkokushi (the Six National Histories), which in addition to "Nihonshoki," include "Shoku Nihongi" (chronicle of Japan, continued), "Nihon Koki" (later chronicle of Japan), "Shoku Nihon Koki" (later chronicle of Japan, Continued), "Nihon montoku tenno jitsuroku" (the fifth national history, covering years 850 - 858, reign of Montoku) and "Nihon Sandai Jitsuroku" (the sixth of the six classical Japanese history texts), and its effects remained until the end of the Edo period.
この「天皇の正統性」「日本の独自性」の主張は、『日本書紀』を含むその後の正史（いわゆる六国史、『続日本紀』『日本後紀』『続日本後紀』『日本文徳天皇実録』『日本三代実録』）の主要なテーマであり、以後、幕末期までその影響が及んだ。
