Hello! By making use of my study-abroad experience in the United Kingdom, I specialize in teaching Chinese in a way that is easy for English speakers to understand. In my lessons, I focus not only on grammar and pronunciation, but also on plenty of role-plays and conversation practice based on real-life situations, so that you can develop truly “usable Chinese.”
I also play the erhu, a traditional Chinese string instrument. Through traditional Chinese music and the sound of the erhu, I aim to create lessons where you can enjoy not only the Chinese language, but Chinese culture itself. If you love music and culture, or if you’d like to learn Chinese through English, I’d be very happy to learn together with you.
Nice to meet you. I have been involved in language education for eight years, teaching a wide range of learners from children to working professionals. In addition to grammar and pronunciation, I enjoy introducing “expressions you can use immediately” in real conversations, as well as cultural differences between China and Japan in an engaging way.
Lessons are customized to each learner’s level and goals, covering needs such as proficiency test preparation, study-abroad readiness, business conversation, and everyday communication. Whether you are a complete beginner or returning to study after a long break, let’s create a supportive learning environment together where no question is left unanswered and you can learn with confidence.

Hello, my name is Ariel Rosenthal. I’m from San Diego, California, USA, and I currently live in Fukuoka, Japan. I have been living in Japan for over three years now and I love Kyushu! My hobbies include cooking, cycling, listening to music, and creative writing.
I studied basic Japanese as a hobby before joining the US Air Force and studying Mandarin Chinese at the Defense Language Institute. After that, I moved to Taipei, where I lived for a year teaching English. I then returned to my hometown to attend the University of California, San Diego, when I was able to study abroad at Doshisha University in Kyoto. Once I graduated, I moved to Japan as soon as I was able, and I’ve been here ever since!
