Japan Pension Refund and Remittance Options for Vietnamese Workers

Two financial facts that agencies rarely explain upfront: the Japanese pension contributions deducted from your salary every month can be partially refunded when you leave Japan, and the remittance services available to Vietnamese workers vary significantly in fees and exchange rates. Both of these have a meaningful impact on your net financial outcome from a Japan placement.

Japan's Lump-Sum Withdrawal Payment (脱退一時金, Dattai Ichiji-kin)

Every SSW worker enrolled in Japan's Employees' Pension Insurance (Kousei Nenkin) has roughly 9.15% of their gross salary deducted as the employee's pension contribution — the employer matches this. The deduction is automatic and compulsory; there is no opting out.

When a foreign national leaves Japan and their residency status expires, they are entitled to apply for the Lump-Sum Withdrawal Payment (Dattai Ichiji-kin). This is not a full refund of contributions — it is a partial payment calculated based on the number of months you were enrolled in the pension system, capped at 60 months (5 years).

How the refund is calculated:

The payment is based on the average standard monthly remuneration during your enrollment, multiplied by a rate determined by the number of contribution months.

For a worker who contributed for a full 36-month SSW contract with an average salary of 180,000 JPY: the refund is approximately 12 × (180,000 × 9.15%) ≈ 197,640 JPY. At 165 VND/JPY, that is roughly 32.6 million VND — a meaningful supplement to savings that many workers do not know to expect.

How to apply for the refund:

• You must apply after leaving Japan — the Japanese pension office (Japan Pension Service — Nippon Nenkin Kikou) will not process applications while you hold an active residence status
• Applications can be submitted from Vietnam to the Japan Pension Service's international mailing address within two years of departure
• You need your Pension Handbook (Nenkin Techo or Basic Pension Number documentation), passport, and completed form
• Processing typically takes 3–6 months; the payment is sent as an international bank transfer in JPY

Important: There is a 20% tax withheld on the lump-sum payment at source. Depending on whether Vietnam has a tax treaty provision allowing a refund of this withholding, you may or may not recover it. As of 2025, the Japan-Vietnam tax treaty does not provide for a full exemption on this specific payment.

Japan's Social Insurance System: What You Are Actually Getting

The mandatory deductions are not just taxes being taken. They provide genuine coverage during your time in Japan.

Health Insurance (Kenkou Hoken): SSW workers enrolled in Shakai Hoken (employees' social insurance) typically receive 70% reimbursement on medical costs through their insurance — meaning a 10,000 JPY hospital bill costs you 3,000 JPY out of pocket. Emergency care, prescription medications, and regular checkups are covered. For Vietnamese workers used to paying out-of-pocket for all medical care in Vietnam, this is a significant practical benefit.

Employees' Pension (Kousei Nenkin): The pension contribution funds the Dattai Ichiji-kin refund on departure, as described above. Workers who return to Japan on a different visa later and re-enroll in the pension system can combine years of contribution.

Work Injury Insurance (Rousai Hoken): This is paid entirely by the employer. If you are injured at work, medical treatment and a portion of lost wages are covered. Many Vietnamese workers in physically demanding industries (construction, agriculture) are unaware they have this coverage — which is relevant if they are injured and their employer suggests using personal health insurance instead.

Sending Money Home: Remittance Options

For the typical SSW worker remitting 80,000–120,000 JPY per month, the difference between remittance services amounts to several hundred thousand VND per month in fees and exchange rate markup.

The main services Vietnamese workers use from Japan:

SBI Remit: One of the most commonly used services in the Vietnamese worker community in Japan. SBI Remit (operated by SBI Holdings, partnered with Kidzuna/SBI Sumishin Net Bank) sends to Vietnamese bank accounts directly. Exchange rate margins are typically 0.5%–1% above the mid-market rate, with fixed fees. For a 100,000 JPY transfer, total cost including all fees and margin is typically 500–1,500 JPY.

Western Union: Available at convenience stores and Japan Post Bank. Fees are higher than fintech alternatives, but the network is widely accessible for workers without Japanese bank accounts initially. The Japan Post Bank partnership means you can initiate transfers at any post office.

Wise (formerly TransferWise): Near mid-market exchange rates with transparent fees. Requires a Japanese bank account and Japanese phone verification — setup takes the first month in Japan. Once set up, typically the cheapest option for large transfers. Vietnamese bank accounts supported directly.

Convenience store kiosks (Seven Bank, Lawson Bank): Accept cash, no Japanese bank account required. Fees are higher than app-based options, but accessible for workers without accounts. Exchange rates at kiosks are typically 1%–2% below mid-market.

General guidance: For regular monthly remittances, the total cost difference between the most expensive and most affordable services can reach 3–5% of the transfer amount. On a 100,000 JPY monthly transfer over 36 months, that is 100,000–180,000 JPY in lost value — equivalent to approximately 16–30 million VND. Setting up a Japanese bank account (available through Japan Post Bank with just your residence card) and using Wise or SBI Remit for regular transfers is worth the one-time setup effort.

Accommodation: What Your Employer Is Required to Provide

Under SSW program rules, employers who hire SSW workers must ensure adequate housing is available. This does not always mean the employer directly provides housing — they may arrange a rental apartment in the worker's name and assist with deposit and guarantor requirements. But they cannot simply leave you to find housing independently upon arrival.

What "employer-provided accommodation" typically means in practice:

• A shared dormitory (4–6 people per unit) with employer ownership or long-term lease, with a deduction of 10,000–30,000 JPY per month from salary
• Or an employer-supported private rental where the employer acts as guarantor and may subsidize the deposit

The quality varies significantly. Some dormitories are new purpose-built facilities with private bathrooms and fast internet. Others are aging company housing with shared facilities. Asking about the specific accommodation before signing is reasonable — ask for photos and the address to check on Google Street View.

Work Culture: What Surprises Vietnamese Workers Most

Based on community reporting and worker feedback groups, three aspects of Japanese workplace culture consistently catch Vietnamese SSW workers off guard:

Unpaid overtime expectations (service zangyou). Japanese workplace culture — particularly in SMEs — sometimes involves staying late without additional pay, framed as loyalty or teamwork. This is technically illegal under the Labor Standards Act, but enforcement relies on workers reporting it. OTIT and the labor inspection offices (Roudou Kijun Kantoku-sho) accept reports in Vietnamese via their hotlines.

Silence during breaks. Vietnamese workplace social norms involve active conversation and community during rest periods. Many Japanese workplaces have quieter break rooms. This is cultural, not hostile — but it contributes to the social isolation that Vietnamese workers in rural placements describe as the hardest adjustment.

Hierarchy and indirect communication. Disagreement with a supervisor is handled indirectly in Japanese professional culture. Understanding this — and knowing when directness is appropriate and when it is perceived as disrespectful — reduces friction significantly in the first year.
