This paper presents an e-learning material that we have been developing for improving learner's accents of Japanese. It will help learners predict the correct accent and if they get it wrong, and also will guide them to recognize it and lead them so that they can correct it by themselves. This e-learning material consists of: (1) rules of accents, (2) checking learners' understanding, and (3) practice to predict the accents by listening to words by each category. One of our future goals is that we will include not only words but also sentences in this material so that learners can practice outside of class.
