Accomplished educator and researcher with extensive experience at Ehime University, specializing in Life History Research and Narrative Inquiry. I have consistently engaged in research on teachers' life history. The research outcomes have been highly regarded by the Japanese Society for Sociology of Education, and numerous papers have been published. Recently, I have been applying the methodologies developed so far to teachers with experiences of leave of absence or resignation, and I am advancing my investigations. I am an emerging and dynamic life historian.
