Karate

Hi, there.
European's friend wants to seem to train the Karate in Okinawa this summer.
They are practicing Shotokan in France.
I also have practiced in the gym in France. (Just one time)
I must take to Okinawa as an interpreter. He said to me that he pays for my plane ticket .
If so, is it good,isn't it?( I wish he remember what he said to me...)
Thus, seven friends will come from France this summer.
They seem to like tropical Kagoshima and Okinawa.
However, it is not possible to endure if there is no air conditioner. Contradicted ?
It will absolutely become hot because it stays at narrow my home.

Anyway, I am looking forword meeting everyone.!!
