This paper is an account of how a group of Japanese English language teachers, who questioned current teacher professional education and English language education reforms, learnt to challenge the dominant discourse and find ways of conducting more democratic teacher professional education. It describes how those teachers, including the author, generated a collective theory on communicative competence through the process of their inquiry. It explains how they came to appreciate the action research methodology used for this study, grounded in reflective practice, which in turn helped to develop the author's understanding of second person action research. It also tells how the teachers learnt to take the initiative in communicating the thinking which informed their practices to others and began to engage in 'communicative action.' As a result of these outcomes, the paper suggests a potential new form of teacher professional learning aimed towards more democratic relationships between participants. It is hoped that the implications of the research findings could contribute to broader discussions about policy pertaining to teacher professional development.
