IROHA - Study Japanese JLPT

This is an app to practice vocabularies, Kanji, grammars and listening to prepare for Japanese Language Proficiency Test (JLPT) including levels N4, N3, and N2. (has support in Vietnamese)
It is designed for non-native Japanese speakers working in Japan to learn Japanese and to prepare for JLPT. Users can check and practice vocabularies, Kanji, grammars, and expressions that are appropriate and commonly used. Vocabularies and Kanji have recordings of native Japanese speakers so this app would help to improve listening skills as well as to check pronunciations.
