English language education in Japan has long been criticized for its traditional methods emphasizing grammar and reading at the expense of communicative competence. This article explores the potential of Artificial Intelligence in Education (AIEd) to address this issue. A review of literature explored critical challenges faced by Japanese EFL learners, including Japanese teachers' low English proficiency and attitudes towards English teaching, heavy focus on entrance examinations in high school, overemphasis on grammar in EFL curricula and textbooks, lack of authentic communicative practice, and differences in cultural values. An examination of technology integration in Japanese education revealed that while many institutions have begun incorporating technology, its widespread adoption has been gradual. Several case studies support the use of AI to address the psychological barrier to speaking by offering a safe and engaging learning environment, thus boosting confidence and fluency. Furthermore, in the Japanese language context, AI can lower anxiety, promote creativity, and offer personalized learning. In addition to the individual benefits, AI empowers institutions to tailor learning needs, teachers to shift their role from instructors to facilitators, and students to become independent critical thinkers. Finally, challenges and limitations are addressed, including ethical considerations surrounding data privacy, overreliance, predictive patterns, and watermarking. Despite potential drawbacks, the benefits of AIEd merit a deeper exploration of its adoption in EFL curricula. AI tools offer a practical solution to prepare Japanese EFL students to communicate in English effectively and confidently and thus participate in the global landscape.
