Koki is kind, smart, and curious about the lives of his students. His English is excellent, and he has a very interesting educational background of sports science and sport in society. I am grateful to have worked together and am excited to improve my Japanese skills with his guidance.

Had a great inaugural lesson with Koki san! He was encouraging, asked questions, and provided useful feedback on my errors.

Koki-san's lesson has been one of the best I've ever had here on Italki! He manages to keep the conversation lively effortless, kindly corrects mistakes and gives alternatives whenever the sentences don't sound extremely natural. I'll book for sure other lessons!
