The present study aims to examine the teaching practice of Japanese language and culture in Korea. More specifically, it studies the extent to which the curriculum of the Japanese language in Korea places an importance of cultural understanding in language teaching, through analysis of 1) the test items appeared in the CSAT for the last five years and 2) educational curriculum of Japanese language in Korea. With the findings, this study discusses teaching implications and suggestions. From the findings, this study claims that language teaching should include not only structure and functions of the target language but also enhancing an ability to build the relationship among people who use the language, to understand diversity of the society in which the language is used, and to develop comprehensive understandings about the language use. Also this study claims that the learner autonomy needs to be promoted, placing an value on ``process`` of learning, rather than ``product`` or ``outcome`` of learning. In conclusion, this study argues that language teaching should help learners understand that culture and language is intertwined, and because of that, there exist a high degree of diversity and complexity going on in language learning.
