Japan’s national health insurance covers you domestically — but the moment you leave the country, you’re uninsured unless you have separate travel coverage. For residents who travel regularly, the right travel insurance policy matters. Here’s how to choose one.
What Japan’s NHI Covers Abroad
Japan’s National Health Insurance does have an overseas claims system (海外療養費) — but it’s limited:
- You pay upfront for all overseas treatment
- You then claim a reimbursement back from your Japanese municipality
- Reimbursement is calculated at Japanese standard rates, not the actual overseas cost
- You receive roughly 70% of the Japanese equivalent cost — which is often a fraction of what you actually paid
Example: A US hospital visit that costs $5,000 might be reimbursed at the equivalent of ¥30,000–50,000 (a few hundred dollars). The gap is entirely your responsibility.
Why You Need Separate Travel Insurance
Medical costs abroad are not regulated the way they are in Japan.
- US hospital: $3,000–10,000+ per day
- UK (private): £500–3,000+ per day
- Emergency evacuation: $50,000–200,000+
NHI reimbursement will not cover these amounts. A single serious illness or accident abroad without travel insurance can result in life-changing debt.
What Good Travel Insurance for Japan Residents Covers
Look for policies that include:
| Coverage | Minimum Recommended |
|---|---|
| Emergency medical | ¥10,000,000+ (or $100,000+) |
| Emergency evacuation | ¥50,000,000+ |
| Trip cancellation | Amount matching your trip cost |
| Baggage/personal effects | ¥300,000+ |
| Liability | ¥100,000,000+ |
Best Options for Japan Residents
Japanese Domestic Insurers
Companies like Sony損保, au損保, and 損保ジャパン offer short-term overseas travel insurance that you can buy online before departure.
- Buy online in Japanese (English support varies)
- Competitive pricing for short trips
- Easy claims process if you’re based in Japan
International Expat Insurance
For longer trips or frequent travelers, international plans from companies like AXA, Allianz, or BUPA International may make more sense than buying per-trip coverage.
SafetyWing — Subscription-Based Travel Medical Insurance
SafetyWing is a popular option among expats and frequent travelers. It works as a monthly subscription — no long-term commitment — which makes it ideal for people who travel regularly or for extended periods. Coverage kicks in while you’re outside Japan (and outside your home country), with an affordable flat monthly rate regardless of destination.
- Monthly subscription — cancel anytime
- Covers emergency medical, hospitalization, and evacuation
- Popular with digital nomads and expats making frequent international trips
- No need to buy separate per-trip policies
Japan's NHI doesn't cover you abroad. SafetyWing covers expats worldwide from ~$45/month — monthly subscription, cancel anytime.

Some premium Japanese credit cards (Amex Platinum, Rakuten Premium, etc.) include basic overseas medical coverage. Check your card’s benefits — it may be enough for short trips to low-risk countries.
What About the Health Insurance from Your Employer?
Company health insurance (社会保険) has similar overseas reimbursement rules to NHI — equally inadequate for actual overseas costs. You still need separate travel insurance.
Short Trip vs. Long Trip
Short trips (under 2 weeks): A single-trip policy from a Japanese insurer bought online is easy and affordable — typically ¥1,000–5,000 for basic coverage depending on destination and duration.
Long trips or frequent travel: Consider an annual multi-trip policy. More cost-effective if you travel more than 3–4 times per year.
Home Country Visits
Many foreigners assume their home country’s public healthcare still covers them when visiting. In many cases it doesn’t — residency abroad may affect eligibility. Check before you assume.
Booking Domestic Travel in Japan
For trips within Japan, domestic flights are sometimes faster and cheaper than shinkansen — especially for routes to Okinawa, Hokkaido, or Kyushu.
