All residents in Japan, regardless of their nationality, are required to pay into the national pension or employee pension plans. However, foreign nationals who leave Japan before contributing for at least 10 years cannot receive pension benefits, meaning they may simply lose the money they have contributed to the pension system. To address this issue, the lump-sum withdrawal payment option was introduced, which allows a partial refund of the pension contributions made. Foreign nationals can claim this partial refund within two years of leaving Japan. Under the current system, foreign nationals can still receive the lump-sum withdrawal payment even if they leave Japan with a re-entry permit. However, once they have received the payment, their pension contribution period resets to zero. This means that if foreign nationals return to Japan and resume making pension contributions, they may still fall short of the 10-year requirement. In fiscal 2022, one in four of those granted lump-sum withdrawal payments held re-entry permits.
