I am looking for some pension and retirement information in Japan. Even though I am only 34, I am thinking about the financial situation in the future. I am Swiss, but have spent the past few years abroad, so I have to count on foreign retirement support.

I plan to spend my next 25 years working in Japan working. Theoretically, I can then receive my pension in Japan.

But how much would it be? How about social security? Can anyone give me an idea how much I can expect, if I pay "properly" my dues for both? As I do not expect it to be a lot, I need additional ways to fund my future living expenses. Are there any information about retirement saving plans in Japan?
