Meet Your Teacher
Nice to meet you. Since 2019, I have taught students of various levels at Japanese language schools in Japan.
After graduating from university, I studied in Canada, where I experienced both the excitement of living in a different culture and the challenges of communicating in another language. Because of this, I understand the worries learners may have, and I hope to help turn those worries into enjoyable learning experiences.
I also have over 20 years of experience in restaurant management. I can help you learn not only everyday conversation, but also natural Japanese for real-life communication with customers, colleagues, and business partners.
