📌 Unemployed Health Insurance & Pension — 핵심 요약 (Key Takeaways)

If there is even a 1-month gap between jobs in Japan, you must switch your health insurance and pension within 14 days (20 days for Voluntary Continuation).
For Health Insurance, compare Municipal National Health Insurance (国民健康保険) against Voluntary Continuation (任意継続) — Voluntary Continuation has a monthly cap and covers dependents for free!
For National Pension (国民年金, ¥17,510/mo in 2026), unemployed residents can apply for the Special Unemployment Exemption (退職による特例免除).

📖 How the Formula Works & Official Terminology (with Local Terms)

Option A — Voluntary Continuation (任意継続): You pay both employee and employer halves (~2x your old payslip deduction), but the calculation base is capped around ¥300,000–¥320,000 and family dependents remain free.
Option B — Municipal National Health Insurance (国民健康保険): Based on your prior-year income. If laid off involuntarily, your prior-year income is discounted by 70% for calculation.
National Pension Switch: Switch from Category 2 (厚生年金) to Category 1 (国民年金) at City Hall and submit an exemption application with your separation notice (離職票).
