This paper clarifies the language learning strategies of learners during Japanese language learning using a computer. Furthermore, questionnaire and interview surveys were conducted to clarify the differences between classroom strategies and learners' own strategies. As a result of the survey, during Japanese language learning using a computer, the following strategies are frequently used: meta-recognition strategy in which learners control learning and evaluate their learning status by themselves; memory strategy in which repetition practice is conducted or images are used; and social strategy in which learning is conduced while cooperating and checking each other using their own network. These results reflect the characteristics of the medium, that is, the computer. At the same time, when learning with a computer, learning is not achieved unless learners actively use the computer. In the future, research will be further implemented based on these results. As well, it is essential to instruct a wide range of learning strategies to learners to allow them to learn more effectively using computers.
