Abstract
This action research as conducted during and after a series of three teaching practice courses offered from the Japanese Language Teaching Practice, he Graduate School of Global Communication and Language, Akita International University. Focusing on the teaching practices conducted in winter and spring, this paper examined and discussed whether or not measures were taken by teachers to alleviate learners' anxiety in learning a second language. The results revealed that active measures were taken to address learners' anxieties about making mistakes. However, the measures addressing anxieties caused by uncertainty in understanding were found to be insufficient. In this study, cases where measures were not implemented are presented, and some ideas for improving them are proposed. The paper also discusses what measures and responses teachers should adopt to alleviate anxieties for learners studying a second language.
