This research investigated the development of an Artificial Intelligence (AI)-based Chatbot tailored for Japanese language learners, employing the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) method as its guiding methodology. The study systematically addresses the needs and preferences of Japanese language learners in the Analysis phase, conceptualizes the Chatbot in the Design phase, and implements it in the Development phase. The AI-driven Chatbot is subsequently deployed in the Implementation phase, allowing for user interaction and continuous evaluation of learner engagement, user experience, and overall effectiveness. Through this research, we aim to demonstrate the potential of AI-based Chatbots as valuable tools for language learning, utilizing the structured approach of the ADDIE method to inform and inspire future developments in the field of Japanese language education.
