❓ FAQ
Do I have to enroll immediately after quitting my job?
You must apply within 14 days of resignation. If delayed, you face a period without insurance and might have to pay full medical costs.
How much does National Health Insurance cost?
It's calculated based on last year's income, household size, and age. Notifications are sent around June. Reductions exist for low-income households.
What about my dependents?
NHI has no concept of dependents; every family member enrolls individually. The head of household applies for everyone at once.
What if I move to another city?
You lose your Ota City NHI qualification. You must enroll in NHI at your new address within 14 days.
