Whether short or long-term, for fun or work, KAI welcomes you and supports your Japanese language learning needs!


Classroom Environment

To avoid the three Cs (closed spaces, crowded places and close-contact settings), the number of students is reduced by half. All teachers and students must wear masks and students are provided with face shields that must be worn during conversation practice.

Originally Developed Health Check App

Students use an originally developed special app to check their health before coming to school. Students also have their temperature measured after they arrive at school.

Disinfecting the Facilities

Disinfectant alcohol is placed at the entrance and in classrooms. Students are encouraged to disinfect their hands when arriving and desks and such when leaving. Staff disinfects the school's facilities with alcohol several times a day. The reception desk is equipped with plexiglass barriers.

  • Why I chose KAI and my impression after enrolling

  • The excellent reputation of KAI’s teachers, curriculum and holistic approach to language learning are what attracted me. For me, passing language exams isn’t as important as being able to understand and use natural Japanese. KAI was the only school I found that used technology and learning methods to effectively achieve my goals. The first thing I found remarkable about KAI was the speed I progressed at. Shortly after starting lessons, I was able to make Japanese friends, order food — basically live independently in Japan. Teachers have been extremely friendly, always available to answer any questions and support my learning.
