I know a lot of foreigners with little to no Japanese and no MBA who work in finance in Tokyo- all at large foreign financial houses like Ernst and Young, Barclays etc. Most of them work as analysts and fund managers.

If you have the experience and are already in Japan (i.e. working as a teacher, even if it's just for a short time), it's possible you will get a job, but remember the financial crisis and the collapse of Lehman brothers etc last year? That put a lot of foreign finance people out of work, and the economy has not really recovered a lot since then. Japanese skills are becoming more important as jobs get more competitive. Being hired from overseas is unlikely, unless you are very special for some reason.

As for the person who wondered whether there are IT jobs for foreigners in Japan- there are loads. The Tokyo offices of companies like HP, Cisco, Axa, Microsoft and many more have English as their working language and hire plenty of non-Japanese- recently a lot of people from India have found jobs here. As with finance though, there are not nearly as many jobs as there were two years ago, and the market doesn't look like it will pick up any time soon.
