There is no choice but receive pension!

Since the qualification for receiving the old-age pension from Japan was shorten from 25 years to 10 years from August 1, 2017, foreign workers/residents may not receive a lump-sum withdrawal payment which is eligible for foreigners who have worked/lived in Japan for 6 months or longer, if you have joined and payed the premium for the pension system here for 10 years or longer.
