Abstract
This article examined comments on Poem Number 7 and 84 in Kokin Wakashu (Collection of Old and New Japanese Poems) from various views on kana no i ni kayou ran which was about the auxiliary verb ramu in the sixth scroll of Motoori Norinaga's Kotoba no tamanoo in order to explore their association with waka poetics and commentaries on classical literature which have not been investigated in great detail. The examination revealed that Poem Number 7, which had been considered to be drawn from Kenchu Mikkan Sho, was actually inspired by Keichu in the Kokin Yozai Sho and the subsequent commentaries on Kokin Wakashu by Kada no Azumamaro and Kamo no Mabuchi, and the interpretation that Poet Number 84 was shizu kokoro naku hana no chirukana, nan to shite shizu kokoro naku hana no chiruran was derived from commentaries on Hyakunin Isshu by Kamo no Mabuchi. Through this historical investigation, I explored the way Motoori Norinaga incorporated the results of the annotation of classics in the study of Japanese literature, which was a rising discipline during his time into his own ideas of Japanese usage.
