Corpus analysis (YUK Japanese essay corpus of Chinese native speakers studying Japanese with taggers 2016, Ver. 6) reveals that the uses of "KARA" and "KARANO", "DE" and "DENO" confuse Chinese Japanese learners. Questionnaire previously conducted by the author with native speakers of Japanese and Chinese Japanese learners being the participants further suggests the tendency of Chinese Japanese learners not differentiating "KARANO" and "NO", "DENO" and "NO". This study investigated the actual uses of case particles "KARA" "KARANO" and compound adnominal particles "DE" "DENO" in Japanese language textbooks, trying to suggest improvement for teaching methods.
