JET pensions

I am working as a prefectural employee and am married to a Japanese national. I am aiming to amass the minimum 22 years of pension contributions necessary to draw a pension in Japan.

I first worked in Japan on the JET program from 1991 for 3 years in the same prefecture where I work now, whereupon I left Japan. It was before the time when contributions could be reclaimed.

I recently phoned the prefectural office and asked if my first three years' contributions are registered. They said no record now exists of my contributions, and I should telephone the school where I worked. They also had kept no record of my time there. Unfortunately, I have not kept any records of my salary from my JET years.
