Japan's Pension System for Foreigners — Complete Guide Series

Last updated: February 2026 ｜ Reflects FY2025 premiums, the 2025 Pension Reform Act, and the 2027 visa-renewal rule

For foreign residents in Japan, the pension system is one of those topics that's easy to ignore — until it isn't.

Every month, a chunk of your paycheck disappears into kōsei nenkin (Employee's Pension), or you're expected to make National Pension payments yourself if you're self-employed, freelancing, or between jobs. If you plan to leave Japan eventually, the natural question is: "Why am I paying into a system I'll never collect from?"

The answer is more nuanced than you might think. Japan offers a lump-sum withdrawal payment that lets departing foreigners reclaim a portion of their contributions. If your country has a social security agreement with Japan, you may be able to count your years here toward a pension back home. And as of June 2027, failing to pay pension premiums can result in your visa renewal being denied — making "just skip it" a genuinely risky strategy.

This three-part series cuts through the complexity and gives you everything you need to make informed decisions about your pension in Japan — whether you're staying long-term, planning to leave, or somewhere in between.

The 2025 reform that raises the maximum from 5 years to 8 years (effective ~2029) is also covered.

Best for: Expats on corporate assignments, long-term residents planning their retirement across countries, or anyone whose home country has an agreement with Japan.

Key Changes in 2025–2027

Before diving into the articles, here are three major developments reshaping the pension landscape for foreign residents.

June 2025 — Pension Reform Act enacted The maximum coverage period for lump-sum withdrawals rises from 5 years (60 months) to 8 years (96 months), though this provision won't take effect until approximately 2029. Workers who leave Japan with a valid re-entry permit will no longer be able to claim the lump-sum during the permit's validity. The Employee's Pension standard remuneration cap will be raised in stages — from ¥650,000 to ¥750,000 by September 2029.

June 2027 — Visa renewal compliance checks begin Foreign residents who fail to pay National Pension and National Health Insurance premiums without a valid reason will be denied visa renewals and status changes. A data-sharing system linking municipal insurance records to the Immigration Services Agency via My Number is being built during FY2026.

Social security agreement expansion — Austria effective December 2025 Austria became the 24th country, joining as a Type A agreement (with totalization). Negotiations with Vietnam began in July 2025.
