Hi there !
I am french who lived in Montreal, Canada, for 6 years. I speak french, but also québecois (different kind of french that we speak in Québec) and english. I have several Japanese friends in Montreal who were learning english or french and I helped them improving their new language. So I might be new to teach in Japan but I was able to lead a friend in his studies.
I am able to adapt a course to your level and focus on what you need.
Thank you !
