This paper reports on the implementation of a teaching practice based on classical Japanese texts aimed at undergraduate international students. Learner interviews and textbooks analysis of undergraduate specialized subjects revealed that graduate and undergraduate university students required a comprehensive understanding of classical Japanese texts in the late 19th century. Consequently, it was decided to allocate specific class time for discussing classical Japanese texts in reading comprehension classes, targeting first and second-year advanced Japanese learners. Meiji-era "Aesop's Fables" were chosen as introductory teaching materials with the assumption that learners who had not yet studied classical Japanese grammar could intuitively grasp classical Japanese texts. Learners were observed to be attentive to grammar, kana usage, archaic kanji characters, and variations in kanji font styles during practical application.
