We would love to support your Japanese.


We always discuss with you how to conduct the lessons, and try to figure out the mystery of Japanese. All of us encourage each other.



Without speaking, your Japanese will not improve. The only way to improve is by repetition

of speaking and studying. Lessons with a teacher would fulfill both of these speaking and

studying requirements to improve your Japanese.

We are flexible. Please let us know of any particular requests you may have.
