How to claim

Leave Japan (move-out notice at city hall). You must no longer live in Japan and have no right to a Japanese pension.
Apply within 2 years of leaving: form 'Lump-sum Withdrawal Payment Claim' + copy of passport (exit stamp / last day), pension book or number, bank details.
Send to Japan Pension Service (Japan Pension Service, Takaido-nishi 3-5-24, Suginami-ku, Tokyo 168-8505). Payment takes about 4–6 months.
For the 20.42% tax: appoint a tax agent before leaving and file a refund after payment.
