Soga no Umako
, alternatively known as Kuni tsu Fumi meaning "National Record", is a Japanese historical text purported to have been written in 620 by Shōtoku Taishi and Soga no Umako. It is recorded in the "Nihon Shoki", but there are no known extant copies. Assuming that it did in fact exist, it would predate both the "Kojiki" (712) and the "Nihon Shoki" (720).
