Japan (JP)
Japan is one of the world's most captivating destinations for expats — a country where ancient temple culture and ultra-modern technology coexist seamlessly.
Social Security in Japan
Benefits, contributions, and how the system works for expats.
Japan's social security system is built on four universal pillars: National Pension (国民年金 / Kokumin Nenkin), Health Insurance (健康保険 / Kenko Hoken or National Health Insurance / 国民健康保険), Employment Insurance (雇用保険 / Koyo Hoken), and Nursing Care Insurance (介護保険 / Kaigo Hoken, mandatory from age 40). All residents — including foreign nationals — are legally required to enroll in these programs. Enrollment in National Health Insurance (NHI) and National Pension is mandatory for those not covered by employer-based (Shakai Hoken) equivalents. Japan has totalization agreements with 18 countries to avoid double contributions. MyNumber (個人番号 / マイナンバー) is the social security and tax identification number for all residents.
MyNumber (Individual Number)
マイナンバー / 個人番号 (Kojin Bangō)
MyNumber is assigned automatically to all residents registered in Japan's Jūmin Kihon Daicho (住民基本台帳 / Basic Resident Register). Foreign nationals receive their MyNumber after completing Jūsho Toroku (住所登録 / address registration) at their ward or city office upon arrival. A notification letter (通知カード / Tsūchi Card) containing your 12-digit MyNumber arrives by post within 2–3 weeks of registration. To obtain a MyNumber Card (マイナンバーカード / Myna Card) — the physical IC card — apply separately online at mynaportal.go.jp or at the ward office and collect in 1–3 months. The card is free.

Benefits & Support Payments
National Pension (Basic Pension)
国民年金 / 基礎年金 (Kokumin Nenkin / Kiso Nenkin)
Japan's universal flat-rate state pension providing a basic retirement income. All residents aged 20–59 are required to contribute for a minimum of 10 years (120 months) to qualify for any pension payment. Full pension (40 years / 480 months) provides approximately ¥816,000/year (¥68,000/month) in 2026. Employees covered by Kosei Nenkin (Employee Pension) also build an earnings-related supplement on top of the basic pension.
All residents aged 20–59 must enroll. Foreign nationals resident in Japan with a valid visa are required to participate. Minimum 120 months contribution for any benefit. Lump-sum withdrawal available for foreign nationals leaving Japan (see pensionLumpSum notes). Students can apply for payment deferral (学生納付特例).
Automatic enrollment is handled by your ward office when you register your address. If you leave an employer without joining a new one, you must re-enroll in Kokumin Nenkin at the ward office within 14 days. Contribution: ¥17,920/month (April 2026–March 2027 rate, flat regardless of income; source: nenkin.go.jp). Pay by bank direct debit, convenience store, or credit card via Nenkin Net.

Employee Pension Insurance
厚生年金保険 (Kosei Nenkin Hoken)
Earnings-related pension for company employees and part-time workers working 20+ hours/week at companies with 51+ employees (from October 2024, threshold reduced to 51 employees). Provides an earnings-related supplement on top of the National Pension (Kokumin Nenkin). Employees pay 9.15% of standard monthly remuneration; employer matches. The higher the salary and the longer the contribution period, the higher the total pension.
Employees covered by employer-based Shakai Hoken (社会保険). Also covers company directors, part-timers meeting the 20h/week and 51-employee thresholds. Foreign nationals on work visas are covered the same as Japanese employees.
Enrollment is automatic through your employer — your employer registers you. When you change jobs, your employer handles transfer. If you leave employment, you fall back to Kokumin Nenkin and must register at the ward office. Track your pension record at nenkin.go.jp or via the Nenkin Net app.
Employment Insurance (Unemployment Benefit)

International Social Security Agreements
Japan has totalization agreements (社会保障協定) with 18 countries (as of 2026): Germany, United Kingdom, South Korea, United States, Belgium, France, Canada, Australia, Netherlands, Czech Republic, Spain, Ireland, Brazil, Switzerland, Hungary, India, Luxembourg, Philippines. These agreements eliminate double contribution requirements and allow contribution periods in both countries to be combined to meet minimum qualifying thresholds for pension eligibility. Check the Japan Pension Service (日本年金機構 / nenkin.go.jp) for the specific terms of your country's agreement.
The Japan social security system is comprehensive but complex. Key pitfalls for foreign nationals: (1) Failure to enroll in NHI after leaving an employer — mandatory, and gaps create arrears. (2) Failure to enroll in Kokumin Nenkin — also mandatory, even if you plan to claim the lump-sum withdrawal on departure. (3) Not tracking pension contribution months — you need Nenkin Net access to view your record. (4) Not claiming the lump-sum pension withdrawal (脱退一時金) within 2 years of departing Japan permanently — the deadline is strict. (5) Totalization agreement benefits require proactive claims in your home country after departure. Consult the Japan Pension Service hotline (0570-05-1165) or an English-language Sharoushi (social insurance labour consultant) for personalised guidance.
