Common pitfalls
Issues that frequently catch people off guard in this area.
Common questions
Can I extend short-term coverage if I stay longer?
Many policies allow extensions, but terms vary. Some require requesting extension before the original end date. Others may require re-underwriting. Confirm extension policies before your initial purchase if there's any chance you'll stay longer.
What's the difference between short-term expat insurance and travel insurance?
Travel insurance typically covers trips up to 30-90 days with emergency focus. Short-term expat insurance is designed for stays of several months to a year, often with more comprehensive coverage including routine care. The right choice depends on your stay length and healthcare needs.
Can I cancel early and get a refund?
Policies vary. Some offer pro-rated refunds for unused months. Others have minimum commitment periods or cancellation fees. Review cancellation terms before purchasing, especially if your plans might change.
Can I use international insurance instead of Japanese insurance?
No, health insurance enrollment is legally required for all residents. International insurance can supplement but not replace Japanese coverage. You must enroll in either Shakai Hoken or National Health Insurance depending on your situation.
How much is the 30% copay in practice?
For routine care, costs are manageable. A doctor visit might cost 1,000-3,000 yen out-of-pocket. However, hospitalization or major procedures can result in significant copays. A high-cost medical care system caps monthly expenses based on income.
Can family members be added to my policy?
Most international health insurance providers offer family plans. Family pricing structures vary—some charge per person, others offer family discounts. Adding dependents is typically straightforward during enrollment or renewal periods.
What happens if I need emergency care before my policy starts?
Coverage typically only applies from the policy start date. If you need care before coverage begins, you'll likely pay out-of-pocket. Plan your policy start date to align with your arrival, and consider travel insurance for any gap periods.
