Reclaim Your Japanese Pension: Lump-Sum Refund Hack

If you have worked in Japan as an international resident, you have likely noticed a chunk of money deducted from your paycheck each month for the National Pension (国民年金 - Kokumin Nenkin) or Employees' Pension Insurance (厚生年金 - Kosei Nenkin). While contributing is mandatory by law, leaving Japan doesn't mean you have to say goodbye to that money forever. If you are departing permanently and have contributed for at least six months, you can claim a substantial refund known as the Lump-Sum Withdrawal Payment (脱退一時金 - Datsutai Ichijikin). Here is the step-by-step hack to getting your money back.

Are You Eligible for the Pension Refund?

To qualify for the refund, you must meet the following four criteria at the time you submit your claim:

You do not have Japanese citizenship.
You have paid pension contributions in Japan for at least **6 months**.
You no longer reside in Japan (you must have officially filed your moving-out notice at your ward office).
You have not yet reached the age to receive old-age pension payments (typically 65).

How Much Money Will You Get Back?

The exact refund amount depends on whether you contributed to the National Pension or the Employees' Pension (Kosei Nenkin), your average salary during employment, and the total number of months you contributed.
Previously capped at 3 years (36 months), the cap was raised to **5 years (60 months)** in April 2021.

Contribution Period	National Pension Refund (Approximate 2026 Rates)	Employees' Pension (Kosei Nenkin) Refund
6 - 11 Months	¥50,000 - ¥90,000	Prorated based on average monthly salary x 0.5
12 - 23 Months	¥100,000 - ¥180,000	Prorated based on average monthly salary x 1.1
24 - 35 Months	¥200,000 - ¥360,000	Prorated based on average monthly salary x 2.2
36 - 47 Months	¥300,000 - ¥540,000	Prorated based on average monthly salary x 3.3
60+ Months (Max Cap)	¥500,000 - ¥900,000	Prorated based on average monthly salary x 5.5

The 2-Step Application Hack

The pension refund process has a catch: when the refund is processed, a **20.42% income tax** is automatically withheld from the Employees' Pension portion. However, you can reclaim this tax portion too! This requires a two-step application process:

Step 1: File for the Lump-Sum Refund (Done from outside Japan)

Once you arrive in your home country, gather the following documents and mail them by post to the Japan Pension Service (Nenkin Kiko) in Tokyo:

Application Form: The Lump-Sum Withdrawal Payment Claim Form (available online in multiple languages).
Pension Book or Number: Your physical blue or brown Pension Book (*Nenkin Techo*) or proof of your Basic Pension Number.
Passport Copies: Photocopies of your passport pages showing your name, date of birth, nationality, signature, and the page containing your departure stamp from Japanese immigration.
Bank Details: A copy of a bank statement showing your home bank account number, SWIFT code, and account name. The bank must stamp the application form directly to verify the account details.

Wait for 3 to 6 months. The Japan Pension Service will wire the money directly to your foreign account (converted to your local currency) and mail you a **Notice of Payment (脱退一時金支給決定通知書 - Datsutai Ichijikin Shikyu Kettei Tsuchisho)**. Keep this notice safe; it is required for Step 2!

Step 2: Reclaim the 20% Withheld Tax (Requires a Tax Representative in Japan)

Since the Japan Pension Service cannot wire tax refunds to foreign bank accounts, you must appoint a **Tax Representative (Nozei Kanrinin)** in Japan before you leave (as detailed in our Leaving Japan Checklist).

Mail the original **Notice of Payment** (which you received in Step 1) to your Tax Representative in Japan.
Your Tax Representative will visit the tax office in the district where you last lived and file a tax return form (*Kakutei Shinkoku*).
The tax office will process the return and refund the 20.42% withheld tax directly into your Tax Representative's Japanese bank account.
Your Tax Representative then transfers the refunded tax money to your foreign bank account (usually via Wise or international wire).

If your home country has a social security agreement with Japan (such as the US, UK, Germany, France, or Australia), you might have the option to **transfer your Japanese pension years** to your home country's pension system instead of cashing out.
Tip: If you plan to return to Japan to work in the future, cashing out will reset your Japanese pension contribution history to zero. If you have contributed for close to 10 years, you may qualify for a permanent Japanese pension in retirement, so calculate whether cashing out or transferring is better for your long-term retirement planning.
