To Have Correct Japanese Language Skills

We teach Japanese to non-native Japanese learners. Judging from our experience, 90% of Japanese learners use incorrect Japanese and often speak rudely, even though they have lived in Japan for many years.

Therefore, we created two services. One is our “private Japanese conversation lesson” and the other is the “Daily Japanese Mail Support” service.

In the “private Japanese conversation lesson,” you can talk with a native Japanese teacher. Let us practice conversation together!

In the “Daily Japanese Mail Support" service, we will check your Japanese using email daily. Please show us the Japanese sentences that you wrote, your pronunciations, your handwritten Japanese characters, and so on. You can also ask us questions about Japanese.
