Hi
The biggest English Conversation School in Japan is Nova.
Have you tried it?
If not, please check:
Nova Group
I'm a student there.
Actually it has some bad reputations, like low salary, not many holidays etc.
But as far as I hear from my teachers, it doesn't sound so bad.
Here is another major schools in Japan

In Japan, learning English is popular now. So there are so many schools from big one like Nova to really small one.
Whereas Chinese is not as popular as English. This language is so complicated, especially pronounciation.
In my opinion, it might be easier for you to seach job as English teacher.
Good luck
