As of December 2009, Osaka Sejonghakdang has 412 Korean language learners. The details can be broken down as following: 76 in Entry course, 169 in Beginner course, 125 in Intermediate course. and 42 in Advanced course. Most of the learners are women, and the number of men is relatively fewer than women. The ages of learners show an even distribution, and people in their forties occupy the largest age group. Though most of learners live in Osaka area, a few learners are from Nara, or Kobe. The majority answered their frist language is Japanese, though there is one person each whose first language is Korean and Chinese. The greatest reason that drives them to learn Korean language is the interests in Korean Culture, and in Korean entertainers. But male learners answer that they do not have any interest in Korean entertainers. More than half of the learners have learned Korean language for two to five years, and 10 of them have studied Korean language for more than five years. 62% of the learners answer they want to learn Korean language up to communicative level, and 37% will study Korean language until they become fluent. This shows that there is a fairly high demand for Korean language. The main reason to choose Sejonghakdang for their learning site is that the quality of education is relatively higher than other places, and the cheap tuition is also one of their considerations. The learners think themselves to be in higher level course than their actual Korean language competence. Learners also answer that they are confident at "speaking" and "reading". On the other "writing" and "speaking" are the hardest part for them. The overall satisfaction about the class is relatively high, and women show higher satisfaction than men. Learners of Korean language have frequently visited and will visit Korea. The main purpose of the visit is general sightseeing and shopping. Learners also come to have more positive view on Korea and Korean culture by learning Korean language and think Korean people with more favorable attitude. The aim of this study is to identify the features of Korean language teaching in Japan by examining the tendency, motivation, and interests of the Korean language learners in Osaka Sejonghakdang. This study suggests what are needed to set up a better curriculum and to enhance the overall understanding on Korean language teaching in the overseas Korean language reaching facilities. An effective teaching method designed with the consideration of the learners` characteristics is required to teach Japanese learners in Japan. Especially, it is imperative that a consideration should be given in the selection of textbooks that can further the understanding on the Korean culture and society. A more careful design of the advanced course is required so that the learners who want to command a good Korean language may have a gradual progress toward the achievement of their goal.
