The purpose of this study was to investigate what factors were closely related to foreign language classroom anxiety (FLCA) among Japanese EFL college students in their communicative English classes. A questionnaire was administered to 252 students. It included the five-point Likert scale questionnaire about FLCA (five items) and risk taking (six items), the three-point Likert scale questionnaire about self-confidence, motivation, hours of self-study, years at college, major, and class-type. The multiple regression analysis of the questionnaire revealed that lower levels of anxiety were predicted by higher levels of self-confidence, risk-taking, and higher percentages of motivation, and longer self-study hours. If students will be more confident, take more risks in class, study English on their own for more hours, and have stronger motivation, their anxiety may be low.
