Bullying and dismissal

I've been working for a private university for almost eight years. During that time, I have put up with constant "ijime" from two other teachers, who finally got their way and are having me fired. No reason was given for my firing.

My question is do foreigners ever win lawsuits in Japan? I see myself suing for the ijime and unfair termination. I would also seek monetary damages for all that money I put into the retirement fund that I'll never see.

Is it even worth the effort to see a lawyer?
