I've never taught English (I do computer work) but do have a lot of 
college-level teaching experience in technical subjects.

I also seem to have a lot of spare time these days, since I do 
programming work out of my house and just seem to finish what I need to 
quick enough so there is extra time.

I was thinking of possibly setting up a side tutoring business of some 
kind. Just as initial "market check" I was wondering - in Tokyo, what 
are the going rates for private English tutoring, both individual 
(adults and children) and small groups?

Are there lots of people looking for private tutors, rather than going 
to the big conversation schools?

Thanks,
