This paper analyzes ‘Korean’ textbooks of Chongryon Korean high school and illustrates their characteristics. There have been 6 curricular reforms in Chongryon Korean schools. The last reform was carried out in 2003. This paper compares textbooks revised in 2003 and those revised in 1993. ‘Korean’ textbooks in the both editions include various genres of classic and modern literary works. Compared to the old textbooks, the new textbooks have less literary works and allot more sections for writing, speaking and listening. ‘Korean’ textbooks emphasize their identity as Korean living in Japan. The textbooks in both editions have many modern works (novels and poems) written by North Korean authors and show strong ideological and political color supporting socialism and North Korea. Such biases, however, get weaker in the new textbooks, with much fewer references to the political leaders of North Korea. Another difference between the new and old textbooks is that while the old textbooks included a foreign literary work in each year, the new textbooks have replaced them with works by South Korean authors.
