Abstract
This study reports on the development and implementation of an automated system using Large Language Models (LLMs) to generate Japanese grammar practice questions for intermediate learners. The system, built using ChatGPT Plus, allows learners to practice intermediate-level grammar patterns through either auto-selected or self-specified methods, providing immediate feedback. User evaluations from four JLPT N2 level students over a two-week period were positive, highlighting the system's effectiveness in enhancing learning efficiency. Future challenges include a more detailed analysis of the naturalness of the generated sentences and user satisfaction with the system's feedback.
