So, my Japanese wife wants me to enroll in the Shakai Hoken and pay the Kosei Nenkin. When I was on the JET program I was able to get about 3 months worth of salary back when I went back to the states even though I returned almost immediately. I am wondering if there I will be eligible for some kind of refund if I leave Japan again after paying for a year or more. Also, I remember that there was a time limit of how long you can be in Japan and still receive the reimbursement, but I don't remember the details of it. If anyone has any information about this I would appreciate it.
