We have developed a spell checker for learners of Japanese. The Japanese spell checker consists of two components. The first component detects and corrects spell errors in input sentences using simple rules. The second component compares the probabilities of both the original sentence and the corrected sentence using a statistical language model (ngram model) which is trained by a large collection of Japanese newspaper articles. The spell checker indicates that the word has an error when the probability of the corrected sentence is higher than that of the original one. In this paper, we report the method of Japanese spell checker and the evaluation results of the method for a real Japanese text written by foreign students. The evaluation results show that the method can find out the local spell errors such as wrong applications of verb inflection rules, but cannot efficiently point out the global errors such as wrong usages of Japanese post positions.
