Abstract
The purpose of this research is to examine the beliefs of good learners who study Japanese as a foreign language. I asked 25 Mongolian students who have just started learning Japanese at Mongolian University to fill in a modified version of BALLI and to have interview. 9 months later, when the result came out, I analyzed the result of the 6 highest learners and 7 lowest. The highest learners tend to have more confidence on their own foreign language abilities than the lowest ones and they have strong will to join the class activity. Furthermore, the former clearly remembered how they learned foreign languages, before they started learning Japanese.
