Exploring Job Options in Japan

Just to bump this thread again...

Haven't lost hope that an opportunity to move to the Japan office at my current job is possible; however, getting very antsy. I've started browsing some sites and considering job searching again. Still unsure... I'll probably give it until the end of Summer but do want a plan in motion just in case.

Considering:

• Pursue an MBA in Japan? Yes I know Japan colleges are now as "prestigious" as American ones, but don't care at this point. Only worry is comfortably taking classes in Japanese
  
• Strictly search for a job, worry about an MBA later.
  

As always, the most depressing reality when searching for Japanese jobs is the ratio of crappy teacher postings to something legitimate. And if it's legitimate, either the Japanese proficiency is likely too demanding or they wouldn't intend to sponsor a visa.

Well... I just hate job searching in general, but at this point I seriously want to make this happen. In the background there's always the chance I can go to Japan as part of my existing company (preferred choice). That being said, waiting for something that may not happen will probably leave me in a worse spot. Any new and useful job sites folks have found? Doesn't help I'm not quite sure what I want to do going forward. Pretty open.
