This study investigated the effects of mnemonics on remembering Japanese hiragana characters by Japanese language learners with an alphabetic background. Our trueexperimental design involved 36 high school students taking classes in Japanese course. In experimental conditions used two class, one class Japanese lessons use an android application and one other class uses flashcards. We investigate the effect of the android application on understanding and remembering hiragana letters, which is expected to be seen which media are more effective in remembering Hiragana letters. The results concluded that mnemonic strategies can effectively be used in facilitating the retention of foreign language scripts, nonalphabetically in real educational settings. Suggestions for future research related to the identified mechanisms are offered which android apps are more effective for learning Japanese hiragana characters. Therefore, the right teaching method, which could teach Hiragana efficiently within a short period, is necessary. Using mnemonic application for learning Hiragana more effective rather than rote learning.
