Claiming Your Lump-Sum Pension
Paying into a pension scheme is a requirement for everyone living and working in Japan over 20. However, if you are planning on leaving Japan permanently, you have two options regarding your pension.
Totalization
With this option, citizens from certain countries can add the time they've contributed to the Japanese pension scheme to that of their own country. The agreements between Japan and each country differ from place to place. Therefore, if you are interested in this option, it is best to speak with your consulate.
Lump-Sum Withdrawal Payments:
If you wish to apply for the lump-sum withdrawal payments, you can recover up to 3 years of pension payments in one lump sum after leaving Japan. If you use this option, you will forfeit your right to claim pension coverage in the future. If you are interested in receiving a lump sum payment, the processes are detailed below.
Please note that you will only receive about 80% of the whole amount of lump-sum payment since it is subject to a taxation method called withholding income tax (about 20%).
