You want to travel to Vietnam? You want to work in Vietnam? Or you are just simply interested in learning the culture? No matter what your purpose for learning Vietnamese is, I can help you! Text book is provided. I can speak conversational Japanese (N3 level), don;t know if it helps but I will try my best to support my student!
Also, I'm studying at Temple University in Minato-ku where everything is taught in English so I can also help you with English!
