In the field of East Asian Buddhist Studies, the investigation and transcription of manuscripts is essential for scholarly advancement. The present article examines the Tōji-gire 東寺切 manuscript fragments, which have been traditionally ascribed to the eminent Buddhist scholar Kōbō Daishi 弘法大師. Recognized for their distinctive non-joined cursive script, these fragments are generally believed to originate from the late-Nara to early-Heian periods. Existing scholarship confirms that the Tōji-gire corpus includes manuscripts of Wŏnhyo’s 元暁 P’an piryang non 判比量論, along with unidentified Yogācāra texts known as Chiehōmon 智恵訪文 and Jintsū-ron 神通論. Nevertheless, the contents of numerous additional manuscripts within this corpus remain unidentified. Recent studies have disclosed that those fragments also contain unidentified texts related to Yogācāra and Buddhist logic. Notably, these recent findings include fragments of previously unknown commentaries on the Cheng weishi lun 成唯識論, among which one fragment is tentatively identified as a manuscript of Wŏnch’ŭk’s 円測 lost commentary.
