JAPN Japan Pension System: Contributions, Refunds and Your Rights
Japan Pension System: Contributions, Refunds and Your Rights
How the System Works
All residents of Japan between ages 20 and 59 are required to contribute to the national pension system (kokumin nenkin). Employees enrolled in company social insurance (kosei nenkin) contribute roughly 9 percent of salary, matched by the employer. Self-employed and non-employed residents pay a flat national pension contribution of approximately 16,500 yen monthly. The pension system provides retirement benefits from age 65, disability benefits, and survivor benefits to dependents.
Lump-Sum Withdrawal for Departing Residents
Foreign residents who contributed to the pension system and leave Japan permanently can claim a lump-sum withdrawal payment (dattai ichijikin) within two years of departure. The refund covers up to five years of contributions (recently increased from three years) minus a withholding tax of approximately 20 percent. The application form (available from the Japan Pension Service website) must be submitted from outside Japan along with your pension booklet, passport copy, and bank details for international transfer. Processing takes three to six months.
All residents of Japan aged 20 to 59 must enroll in the national pension system (kokumin nenkin), paying monthly premiums of approximately 16,500 yen. Employees at companies with more than five workers are automatically enrolled in the more comprehensive Employees’ Pension Insurance (kousei nenkin), with premiums split between employer and employee and deducted from salary. Foreign residents who pay into the system for fewer than 10 years (the minimum qualifying period for benefits) can claim a lump-sum withdrawal payment (dattai ichijikin) when leaving Japan permanently. This refund covers up to five years of contributions (recently expanded from three) and must be claimed within two years of departure. The refund amount depends on the salary level and number of months paid, typically ranging from 300,000 to 1,500,000 yen. Japan has social security agreements with over 20 countries that allow pension contribution periods to be combined between countries, preventing double coverage and enabling benefit qualification through combined service years.
The lump-sum withdrawal payment for departing foreign residents is calculated based on salary category and months of contribution. For the national pension system, the current maximum refund covers approximately five years of contributions at a standardized amount. For the Employees’ Pension, the refund is based on actual salary and contribution history. Filing the claim requires: a pension handbook or basic pension number, passport copy, bank account details for the receiving country, and a completed lump-sum withdrawal form submitted by mail to the Japan Pension Service within two years of departure.
The Lump-Sum Withdrawal Payment
Foreign residents who leave Japan permanently and have contributed to the pension system for at least six months can apply for a lump-sum withdrawal payment (dattai ichijikin) within two years of departure. The payment returns a portion of contributions but not the full amount, and the refund is subject to a 20.42 percent tax withholding that can be partially recovered by filing a tax return through a tax representative (zeimu dairi-nin) appointed before leaving Japan.
The application requires submitting a claim form to the Japan Pension Service after deregistering from National Health Insurance and returning your My Number card at the ward office before departure. Processing takes approximately two to six months, with payment made to your overseas bank account. For residents from countries with social security agreements with Japan (including the United States, United Kingdom, Germany, Australia, and several others), pension contribution periods can be combined with home-country pension calculations, potentially qualifying you for a Japanese pension payment upon reaching retirement age even if you worked in Japan for only a few years. Consulting with a shakai hoken roumushi (social insurance and labor consultant) before departure ensures you make the optimal choice between withdrawal and long-term pension retention.
