I am Andy from Tokyo. I just got back to Japan from California last February. Now I am thinking of starting the language exchange club in Tokyo. The system is quite simple. Members are consist of Japaneses and foreigner. We just talk about topics which you want in Japanese and English. And we change languages every 30min. If there are any mistakes, just correct each other. I held a same type of club in California and Osaka. I will hold a kick off party on Sep. 29th in Tokyo.
If you are interested in the club, let me know.
Foreigner and Japanese both are quite welcome.
