Google Review

"Kai's in central Tokyo so no complaints here. I really loved all of the teachers. Classes were perfectly sized and quite diverse! Even though there were just 10 students in the class, it was still fascinating to learn about other cultures as well as Japanese. I really enjoyed my time at Kai Language School and the great classmates, along with the awesome teachers, made a huge difference."

Facebook Review

"Knowledgeable and supportive Kai teachers made my language school experience in Tokyo fun and memorable. I attended a 3-month conversation course and it was one of the best decisions I've made since I came to Japan. Not only did I learned a lot of Japanese, but I also enjoyed very much the positive vibes of the classroom. I highly recommend a 'practical conversation course' for anyone who wants to improve their Japanese speaking skills."

Culture Trip

"Located in Shinjuku, this central school has been helping foreigners become fluent since 1987, and during that time they've become one of the most popular go-to schools for long and short term residents. They offer a variety of courses for all purposes (business, fun, survival) and also have special accommodation connections if you still haven't yet figured out a place to live. For a fully immersive experience, it may be worth considering a homestay with a Japanese family, this is something Kai can help you out with."
