The purpose of this paper is to compare the kanji pronunciation represented in the guiding notes added to the two Chinese texts, the Qun Shu Zhi Yao in the Kanazawa Library and the Honchomonzui in Kuwonji Temple. Whereas the Qun Shu Zhi Yao is a classical Chinese work, the Honchomonzui is a "Japanized Chinese text" written by Japanese writers. Both of the texts were transcribed with guiding notes by Kiyohara no Noritaka in the second half of the 13th century. Although these guiding notes were added by the same person in the same era, they are completely different. This shows that the traditional research method on the pronunciation of kanji, in which classical Chinese texts have been given priority over "Japanized" ones, should be reconsidered.
