In this paper, the state and history of teaching Japanese language on global and national scale was analized. The interest in Japanese language, and consequently the number of Japanese language students is constantly growing, both globally and in Croatia. Currently, the teaching of Japanese language in Croatia is mainly centralized in the Zagreb area, hence the development of the Japanese Language Subject Curriculum for secondary schools would enable its learning to students from other areas of Croatia. Based on the results of the analysis of the state of Japanese language teaching in Croatia, a proposal for Japanese Language Subject Curriculum for secondary schools in Croatia was written. The content and structure od the curriculum proposal are based on the analysis of the existing Japanese language curricula of foreign countries and on the foreign language subject curricula of the Republic of Croatia. In the proposal, educational outcomes are elaborated and topics and grammar contents for two school years of high school are proposed. Recommendations of teaching methods and cross-subject topics correlated with Japanese language were also listed.
