ようこそ！(Youkoso, “Welcome!”). I’m John Fotheringham, a linguist, teacher, and the author of Master Japanese. After having taught myself both Japanese and Mandarin, I now teach others to do the same―no matter where in the world you are. Through my podcast (The Language Mastery Show), my 150+ free articles and resources, and my 1-on-1 tutoring, you’ll feel inspired with proven strategies to become fluent and feel confident speaking.
