The imperial decree on New year's day in 708 of "Shoku Nihongi" (Chronicle of Japan Continued) contains the description 'A man who run away to the countryside with the banned book will be panished as notified at first if he does not turn himself in' which shows that documents inconsistent with 'the legitimate ideology (Nihonshoki)' of Yamato kingship remained during this period.
『続日本紀』和銅元年正月（708年）の詔に「亡命山澤。挾藏禁書。百日不首。復罪如初。」とありこの時期にはヤマト王権の「正規のイデオロギー（日本書紀）」と相反する書物が残っていたことを示している。
