LI Yu was a famous playwright and novelist in Ming and Qing Dynasties. His work Ten Xiqu Plays of Liweng, on its introduction to Japan, was highly appreciated by Edo literati and later became a favorite target of literary imitation and adaptation. Representatives of Japanese Edo literature, like Kyokutei Bakin, Santou Kyouden, Ishikawa Masamochi, etc., have all been more or less influenced by LI Yu’s plays, which find expressions in their masterpieces. Therefore, the paper aims to elaborate on the specific traces of LI Yu’s influence through the analysis of the similarities between his plays and the novels of Japanese Edo period, such as Kyokutei Denki Hanakanzashi, Sakurahime Zanden Akebono-zoshi, Hida no Takumi Monogatari,Omi Agata Monogatari and so on. After the research, this study comes to the conclusion that Edo Literature has not only absorbed LI Yu’s creative methods in terms of its structure, plot, characters, etc.,but also accepted the themes of his plays and his literary concept of poetic justice. Moreover, in the process of influencing the Edo literature of Japan, LI Yu’s plays underwent different degrees of variation, which also promoted the prosperity of Edo literature.
