Abstract
The authors decided to create learning materials using Monoxer, considering that it could serve as a useful tool for learners to connect their kanji learning with autonomous study. Monoxer supports handwritten kanji input, allows the creation of original materials, enables adjustment of difficulty levels, and provides visualization of learners’ progress. To avoid placing an excessive burden on the learners, a careful selection of kanji was made, and four types of exercises were developed: writing kanji, understanding the meaning of kanji, reading kanji, and a review test.
