Lump-sum Withdrawal Payments (Exclusively for Non-Japanese Citizens)
If you are not a Japanese citizen and you had resided in Japan and had been covered by the Japanese system for a short time, you can claim the Payments within two years after your departure from Japan. You can claim the Payments if you have at least 6 months of due coverage periods under the National Pension system (contribution-exempted periods are proportionally calculated) and you are not eligible for pension benefits.
