Impression of a participant

A Japanese course out of your expectation

In the beginning, I just wanted to learn about business Japanese. However, after joining this course,
I’m learning about the business of Japanese manners and a couple of Japanese cultures. So it’s really out of my expectation!
Kudan’s teachers put a lot of effort into this course, and they can easily explain complicated grammar and business Japanese to me.
I love their small-class teaching, where teachers can make personal comments and advice to each student.
Even though I’m in Hong Kong, I can finish this course online.
Thank you so much for giving me this opportunity to enhance my Japanese, and I really recommend this course to those who want to learn business Japanese!


I am very glad to have taken this course.
It helped me build communication skills in formal Japanese and gain practical knowledge about job search, interview processes, current trends in Japanese job market, workplace culture and business etiquette with ample opportunity to put theory into practice.
Many thanks to all the teachers!
