I looked it up online and found a source that says you have five years after you receive your pension refund, which I received, but when my representative went last year to apply for the tax portion and he was turned away. The tax office said “the tax year was wrong” (whatever that means). So I had my Japanese friend call but we got the run-around where no one seemed to know the answer, and we were transferred between three people without ever getting a concrete answer. Anyone have personal experience with this?
