? Student Voices|What Our Students Say

Business Japanese online class student Sara from Portugal reviewing keigo and email writing skills

Sara (Portugal)

As a long-term student, when I heard that Japonin was going to start doing business classes, I couldn’t wait to try them out. My current job involves dealing with Japanese clients, so I was looking forward to improving and developing my professional Japanese.

Classes cover a range of different skills such as calls, emails, presentations, general etiquette, etc. Each class has a topic in which we practice different scenarios in a specific skill.

These lessons help build confidence to deal with any matter in a business environment. But they are not just suited for those whose work involves Japanese—if you are interested in learning about the Japanese working environment or learning how to better communicate in a formal setting, these lessons are also great.

I’m looking forward to carrying on taking these classes and improving my knowledge even further.

Business Japanese student Anya from Hong Kong reviewing keigo and workplace communication

Anya (Hong Kong)

I started taking Business Japanese lessons at Japonin last year. I found the lessons not only help me understand how Japanese communicate during work, but also give me more context on the culture, processes, and the communication norms between colleagues and with upper management.

The role-plays with commonly used phrases on how to ask for information and clarification, how to report an issue, and how to express agreement or disagreement are very handy. I am now using them when I communicate with Japanese counterparts, which makes my communication look a bit more professional.

I highly recommend these lessons for those who need to communicate with Japanese.
