The book was considered important in later generations, and annotations such as "Kuji Kongen Shushaku" (annotation on Kuji Kongen) (Kenrin MATSUSHITA), "Kuji Kongen Guko" (My thinking on Kuji Kongen) (Fusatsune HAYAMI), and "Kuji Kongen Shinshaku" (New Interpretation of Kuji Kongen) (Masanao SEKINE) were written.
後世に重んじられ、『公事根源集釈』（松下見林）・『公事根源愚考』（速水房常）・『公事根源新釈』（関根正直）等の注釈書が書かれている。
