Compared to what you can do with a masters in business administration in the US or any business related job, English teaching is not going to match that as far as income. Maybe after three years experience and making all the right contracts you could find a couple of jobs that combined would give you the equivalent.

The best job for you would probably be as an executive recruiter or working for a US firm in Japan. Recruiters make up the second largest profession in Japan for English speakers following teaching. Another option would be to start at one of the big teaching companies and work your way up into some sort of management postion which would take you a year or two.

Overall though, I am not 100% sure you are ever going to be able to match your earning potential in US by working in Japan. Why? Japanese companies have a different way of paying their employees that results in the lower level making more than US counterparts and the upper execs making less.
