In Japanese language teaching, improving Chinese students' listening ability has long been a persistent challenge. Listening comprehension remains the most challenging and weakest aspect of students' Japanese learning experience. Many students report uncertainty about effective listening study methods, difficulty keeping pace with listening exercises, slow response times, and particularly struggle with understanding vocabulary in listening materials, which impacts their overall comprehension. This research aims to explore methods for improving Chinese learners' Japanese listening ability by examining Chinese-Japanese kanji similarity. Through literature analysis and questionnaire surveys, this study investigates the impact of Chinese-Japanese kanji similarity on Japanese learners' listening study and ability improvement, seeking to identify effective classroom teaching methods and training approaches for listening comprehension.
