I think Akane sensei’s biggest advantage is she learnt mandarin and went study abroad before. She knew from the angle of non-native speaker the differences between the languages and the struggles one had to go thru’. Of course, like she said, she’s glad to have the teachers, as native speakers, to pretend making mistakes and hesitated in their answers, I think her background gives her a unique advantage to a large extent. I like learning Japanese from 秋山くんのチャンネル and his wife’s channel. But there are definitely many 留学生生徒たちthat are in Japan and studying more seriously in language schools. A good program is really hard to find. Glad that you are going that route.
