Japan Pension (Nenkin) Refund Guide 2025: Get 100% Back

If you've worked in Japan for 3-5 years, you've likely paid thousands of dollars into the national pension system (Nenkin). When you leave Japan permanently, you have the RIGHT TO CLAIM IT BACK. This is your hard-earned money, don't leave it behind!

The refund process is divided into two stages:

• Stage 1 (Claiming 80%): This money is transferred directly to your bank account in your home country.
• Stage 2 (Claiming the remaining 20%): This portion is initially withheld by the tax office. You must file a tax return to get it back.

PART 1: CALCULATING YOUR REFUND

The amount you receive is not 100% of exactly what you paid, but calculated using a formula: Refund Amount = Average Monthly Salary × Payout Multiplier.

• Average Salary: Total income over the working period / total months worked.
• Payout Multiplier:
  • 12 months: 1.1 payout factor.
  • 24 months: 2.2 payout factor.
  • 36 months (3 years): 3.3 payout factor.
  • 60 months (5 years) (New rule from 2021): 5.5 payout factor.

Example: Your average salary is 200,000 JPY. You worked for 3 years. => Total payout: 200,000 JPY × 3.3 = 660,000 JPY.

• Stage 1 (80%): ~528,000 JPY.
• Stage 2 (20%): ~132,000 JPY.

PART 2: CLAIMING THE 80% (DO IT FROM YOUR HOME COUNTRY)

Once you've officially left Japan (canceled your residency and handed in your Residence Card), prepare the following documents to mail to Japan:

1. Lump-sum Withdrawal Payment Claim Form: Download from the official Japan Pension Service website. Fill it out clearly in block letters.
2. Passport Copy:
   • The page with your photo and personal details.
   • The page with the Departure Stamp indicating your final departure from Japan (Very important! If passing through automated gates, ask the officer for a stamp).
3. Pension Book (Original): The blue book.
4. Bank Account Details (In your home country):
   • Account holder name must be YOURS.
   • Bank Name, Branch Name, Swift Code.
   • Tip: Get the bank to stamp the application form, or attach a certificate of the bank account.

PART 3: CLAIMING THE REMAINING 20%

You can only do this after receiving the Stage 1 money and the "Notice on Payment" document. Because this 20% is held by the Japanese Tax Office, and they don't transfer money internationally, you MUST have a Tax Representative in Japan to receive it for you.

1. Send documents to your Representative:
   • The original "Notice on Payment".
   • Passport copy.
   • Power of Attorney (Declaration of Naming a Person to Administer the Taxpayer’s Tax Affairs).
2. The Representative files the claim:
   • They visit the tax office (Zeimusho) with jurisdiction over your last registered address or company in Japan.
   • They file an Income Tax Return for the refund.
3. Receive the money:
   • After 1-2 months, the money is deposited into the Representative's Japanese bank account.
   • They then transfer the money to you in your home country.

CONCLUSION

Claiming the initial 80% is very straightforward and you should definitely do it yourself to avoid paying hefty agency fees. For the remaining 20%, if you don't have a trusted friend in Japan, hiring an agency might be your best option. Make sure to get every penny you've earned!
