There are three basic processes in learning Japanese language-learning, memorizing and forgotten. Memorization can be considered as the key process of efficiency in learning whereas forgotten is the problematic step in learning. It is especially critical to emphasize on memorization when learning Japanese. Without memorization, every previously learned grammar, sentence patterns or vocabulary would have to be re-learned from the beginning. In order to enhance and retain the language in memory and not to be easily forgotten, one should not simply learn the language and then try to make up any deficiency later. It is necessary to prudently design teaching materials in order to achieve the highest efficiency in learning. This article discusses the different learning patterns between left brain and right brain. The correlation between memory of learning and incorporations of comics and illustrations in teaching materials is also analyzed.
