Two textbooks for teaching Japanese as a foreign language were analyzed to extract the relationships between nouns and verbs and the appropriate particles in simple Japanese sentences. A computer based drill to learn Japanese particle usage, that can be used over the internet, was developed by using these relationships. In this drill, the text is displayed with illustrated pictures to indicate the correct verb group and how to correctly use the particle. The average test score for learners with pictures was significantly higher than the score without pictures. The pictures were more effective for those sentences that contained more than one particle. In addition, this method has a significantly larger effectiveness for learners who speak Indo-European languages.
