Abstract
It is commonly trusted that grammar of foreign language which is similar to one's first language is easier to be acquired. However, even though Korean and Japanese have similar concept of transitive and intransitive word, it seems there is no clear benefit for Korean students to learn the same grammar in Japanese. In this paper, I shall suggest the possibility of learning the grammar of English, whose transitive and intransitive word are determined by the existence of object, affects learning Japanese based on Korean school curriculum.
