The practice through the handwriting character actually is effective for acquiring like this complicated Japanese. In this study, we construct Japanese writing method learning system using the on-line character recognition technique. We construct the handwritten reference character database of daily use Kanji character, hirakana and katakana about 2000 character including the writing order of the character. The radicals such as "Hen", "Tsukuri" and the fair handwriting rule are also contained in this database. The learner inputs the practice character in the handwriting using the tablet. The system detects and evaluates letter shape, stroke shape, stroke order and the writing speed of the input character. After evaluating the input character, the system returns the instruction on the writing method with the right character to the learner. This system is developed on Web. We prepare evaluation module of the input character and the reference database on Web server. The learner can practice how to write Japanese properly from Web client of the input unit.
