We co-create scripts with learners for the scenes you’ll use tomorrow—focusing on the exact words and steps that get things done. We prioritize clarity, communication ability, and nuance (politeness, phone etiquette, tone) over vocabulary size, reducing misunderstandings. We specialize in pronunciation of non-native sounds to maximize understandability.

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!

メッセージ:大家好!我来自美国加利福尼亚州的圣地亚哥,目前居住在日本福冈。来到日本已经三年多了,我非常喜欢九州温和的氛围和人们的热情。我的兴趣爱好包括烹饪、骑行、欣赏音乐,以及创意写作。
我在高中时期因为兴趣开始学习初级日语,后来又学习了中文。
再后来,我考入加州大学圣地亚哥分校(UCSD),在读期间还有机会到京都的同志社大学留学。毕业之后,我不再只是想着“总有一天想住在日本”,而是下定决心“现在就去日本”,并尽可能快地移居到了日本。从那以后,我一直以日本为生活基地,希望通过英语教育,成为连接不同语言与文化之间的一座桥梁。
