By revision of the 2011 the Course of Study (MEXT, 2008), elementary school English education became compulsory, and it is now held weekly for students in higher grades. This study aims to reveal what kinds of changes can be seen in the teachers engaged in primary English education after the implementation of the Course of Study revised in 2011. To answer the research questions posed, we examined the changes seen in the teachers over the past five years by comparing data obtained using the same questionnaire study conducted in both 2012 and 2017. The results showed that: (a) there was an increase in teacher's own intrinsic motivation in foreign language learning; (b) there was no change in teacher beliefs over the five years; and (c) there was a tendency that teacher-led class practice different from teacher's belief was increasing.
