Pension expectations for foreign residents
- Kosei (Employees' Pension): If you've worked at a Japanese company on Employees' Pension for 10+ years, you'll get a Japanese pension at 65 (or earlier with discount). Average for 30-year contributors: ~¥150,000-200,000/month.
- Totalization agreements: If you've contributed to pension systems in multiple countries that have totalization agreements with Japan (US, UK, Germany, Korea, etc.), the periods can be combined. Each country pays based on contributions there.
- Lump-sum withdrawal (脱退一時金): If you leave Japan with less than 10 years of pension contributions and your country doesn't have a totalization agreement, you can claim a lump-sum withdrawal. See our lump-sum withdrawal calculator.
- Receiving Japanese pension from abroad: Japan's pension can be paid to your overseas bank account if you've left Japan. It's still taxed by Japan (20.42% flat withholding) unless your tax treaty reduces it.
Building retirement assets in Japan
- NISA: ¥3.6M/year contribution limit, all gains tax-free for life. Most powerful tool for accumulation. See our NISA simulator.
- iDeCo: Personal defined contribution pension. Contributions are tax-deductible from current income. ¥23,000/month for employees, more for self-employed.
- Corporate DC / Kosei Nenkin Kikin: If your employer offers it, contribute the max. These build on top of the basic pension.
- Taxable brokerage: For assets beyond NISA/iDeCo caps. Gains taxed at 20.315% (separate, not aggregated with salary).
