Because of my How to Speak Fluent Japanese Without Saying a Word videos, I get many Youtubers every week emailing me and asking how they can learn Japanese.
Since I lived in Japan from the time I was a very small, white baby, I never had to worry much about learning to speak Japanese. My videos with Remi-chan are my best attempt to teaching the Japanese language. For those who want more, I recommend that you learn Japanese from the internet's most handsome French Bulldog Maggie Sensei. Maggie teaches English and Japanese on her very handsome website. http://www.maggiesensei.com/jp/
There are new lessons uploaded frequently and you can learn all kinds of useful phrases and vocabulary.
If you are trying to study Japanese, I hope you will check it out.
