The purpose of this study is to estimate the future of second foreign language (hereafter, second FL) education after the high school credit system by understanding the primary/secondary teachers’ perceptions of second FL and the actual organization/operation status of second FL, and then to seek the proper tasks and solutions to expand students’ right to choose subjects, which is the purpose of this system. 324 primary/secondary school teachers participated in this study and the results are as follows. First, the languages the teachers preferred the most and would like to recommend to students were Chinese, other languages, French, and Japanese, in that order. Second, in the results of verifying the value of second FL education the primary/secondary teachers reported that overall they not only perceived the necessity of second FL education but also strongly agreed on the necessity to open various second FL subjects. Third, regarding the status of second FL subject, both Chinese and Japanese were overwhelmingly found in secondary school and a subject presented as a choice to students inquiring about their preferences and demands. This implies that the imbalance in second FL education originated not from students’ demand but from the imbalance of second foreign language teachers.
