I live in Dalian Development Zone, this side of the Japanese companies are really a lot of, if your Japanese spoken conversation is good, find a translation job no problem. If you can speak Japanese well, you will have no problem finding a job as an interpreter, or if you can speak Japanese and do IT work related to programming, you will be able to find a good job. As long as you speak well, you can still find a job.
The ability is more important than the certificate!
