Abstract
Our research aim is to investigate how Japanese Language Teachers (JLT) develop their careers. In this study, we focused our research analysis on two issues. The first was about how part-time JLT start their careers as teachers. Concerning this issue, we found some similarities among interviewees and classified them in four patterns. The second issue was about how job experiences change JLT jobs, and as a result we found that JLT who began their Japanese teaching job in the private language schools changed their workplace to national/public universities where job conditions are better after 4 years and 6 months (average time).
