When it comes to the pension system in Japan, did you know that either your employer enrolls you (Employees Pension), or you need to do it yourself? In last week's Lifelines Steve asked whether enrollment automatically happens 36 months after you arrive in Japan, and questions about the lump sum payments.
Short answer: You aren't automatically enrolled in a pension scheme unless your employer handles this for you.
There's more to that, though, which you can find here:
