In order to examine how Korean University student is doing Japanese self - learning. This investigation is check of the effort which touches Japanese being performed independently in outsides the school. The result of the investigation of 4 skills was as follows. Hearing> Reading> Writing> Speaking. I considered the way to utilize a way of their self - learning for classroom activity according to 4 skills. I introduce the way tried at the lesson. I`d like to support and increase Japanese force using student`s self - learning. In ``Hearing`` was being used a lot of Japanese animation. In ``Reading`` was used many Japanese book and magazine. ``Writing`` of the self - learning was most that study to obtain a license and for a periodic test at school. In ``writtening`` there was hardly a student enjoying self - learning. And a result showed "Speaking"of the self - learning by myself is very difficult. We did a classroom learning activity based on these results. Moreover a student improves that. he learning is linked to improvement of new self - learning. Students would be able to develop faculties joyfully and by themselves by repeating those learning. I think it more effective learning. I`d like also to support from now on so that student can work on self - learning personally. I`d like to support it students make a plan by himself, and carry out. I`d like to introduce the way a student can carry out personally at the Japanese lesson.
