Japan is one of the world's most seismically active countries. Most major cities carry a measurable probability of significant earthquake activity — and some, like Nagoya and Osaka, sit in the projected impact zone of a Nankai Trough event estimated at 70–80% probability within the next 30 years.
Despite this, a large proportion of international travellers to Japan carry travel insurance that explicitly excludes earthquakes and other natural disasters in its base policy.
This post explains the gap, how to close it before you travel, and what documents to collect if you need to make a claim.
The exclusion most travellers don't read
Open the exclusions section of a standard travel insurance policy and search for any of these phrases:
- "Natural disaster"
- "Act of God"
- "Force majeure"
- "Earthquake, volcanic eruption, tsunami"
In most base travel insurance policies from most countries, these terms appear in the exclusions list — meaning claims resulting from these events are not covered under the standard policy.
This exclusion applies to:
- Medical costs from injuries sustained in an earthquake (broken bones, lacerations, crush injuries)
- Additional accommodation costs if your hotel is damaged, declared unsafe, or the surrounding area is evacuated
- Flight delay and cancellation costs when the carrier cites "natural disaster" or "force majeure" as the reason
- Pre-booked tour or activity no-show penalties caused by an earthquake evacuation
The one thing that changes this: a natural disaster rider (sometimes called an earthquake rider, Acts of God coverage, or force majeure extension). This is typically an optional add-on to a base policy. Check whether yours includes it, and if not, whether you can add it before departure.
Credit card travel insurance — the automatic coverage that comes with some premium cards — almost universally carries the same natural disaster exclusion. Do not assume credit card coverage is sufficient for Japan travel.
Four things to check in your existing policy
Before travel, locate your policy document (not the summary card — the full document) and verify these four points:
1. Does your medical coverage apply when injuries are caused by a natural disaster?
This is the most important check. Some policies cover medical costs regardless of cause; others specifically carve out earthquake-related injuries. The wording to look for is whether "natural disaster" or "earthquake" appears as an exclusion under the medical coverage section.
2. What is your medical coverage limit?
Japan's healthcare system is excellent but expensive for visitors — you are not covered by Japan's public health insurance as a tourist. Rough cost benchmarks:
| Medical situation | Approximate cost in Japan |
|---|---|
| Emergency room visit (without admission) | ¥30,000–80,000 |
| Simple fracture treatment | ¥100,000–300,000 |
| Emergency hospitalisation (per week) | ¥500,000–1,000,000+ |
| Emergency surgery | ¥1,000,000–3,000,000+ |
A policy with USD 20,000 in medical coverage sounds substantial — but a week's hospitalisation following an earthquake injury can exceed it. Aim for coverage that would handle at least a week of hospitalised care plus emergency medical transport.
3. Does flight cancellation coverage apply to natural disasters?
"Trip cancellation" and "flight delay/cancellation" coverage in many policies applies only to specific named reasons — illness, bereavement, airline insolvency. If "natural disaster" is not explicitly listed as a covered reason, a cancelled flight due to an earthquake is your out-of-pocket expense.
4. Does your policy cover additional accommodation costs during an evacuation?
If the area around your hotel is cordoned off after an earthquake, or the hotel itself is structurally compromised, you may need to find alternative accommodation at short notice and at elevated prices. This cost is not covered by most base policies without a natural disaster rider.
How hospitals in Japan handle payment for visitors
When you need medical care in Japan as a foreign visitor, one of two payment arrangements applies — and which one you have depends entirely on your insurer.
Direct billing (payment guarantee)
Some international travel insurers have partnerships with Japanese hospitals. If your insurer offers this:
- Call your insurer's emergency line before going to the hospital.
- The insurer contacts the hospital directly to authorise and guarantee payment.
- You receive treatment without paying at the counter.
- The insurer settles the bill with the hospital afterward.
This is significantly less stressful than the alternative — especially during a post-earthquake situation when cash and card access may be disrupted. Check before your trip whether your insurer offers direct billing in Japan and, if so, which hospitals.
Out-of-pocket and claim
The more common arrangement for most travellers:
- You pay the hospital bill by cash or card at the time of treatment.
- You collect all documents before leaving Japan (see below).
- You submit a claim to your insurer after returning home.
The reimbursement timeline and process vary by insurer. Some process claims online within days; others require physical mail. Check your insurer's process in advance so you are not caught without the right documents.
Documents to collect for an earthquake-related claim
Whether you are claiming for medical costs, cancelled flights, additional accommodation, or all three, the supporting documents are the same. Collect these at the time of the event — do not try to reconstruct them later.
For any earthquake-related claim
- JMA earthquake alert or warning screenshot — Take a screenshot from the Japan Meteorological Agency alert (available at jma.go.jp in English, or via the NHK World app and J-Alert notifications). Include the date, time, and seismic intensity. This is your proof that an earthquake event occurred on the claimed date.
For flight cancellation or delay
- Airline-issued cancellation confirmation — Request a written confirmation from the airline counter or download it from the airline app immediately. This document should state "natural disaster," "seismic event," or equivalent as the reason for cancellation.
- Receipts for all out-of-pocket expenses during the delay — Hotel, meals, transport. Convenience store receipts and restaurant receipts count; handwritten informal receipts typically do not. Keep originals.
For medical costs
- Doctor's report or medical certificate — In Japanese, request: 診断書 (shindansho). This document states your diagnosis and treatment.
- Itemised hospital bill — The breakdown of all charges. Request: 診療費明細書 (shinryo-hi meisaisho).
- Prescription receipts if medication was dispensed.
- All payment receipts — Every payment you made at the counter.
Supporting identity documents
- Passport copy (photo page)
- Flight itinerary or e-ticket (proof you were in Japan at the relevant dates)
Photograph every document before leaving Japan, and store copies in cloud storage. Document loss after returning home is one of the most common reasons claims are delayed or rejected.
If you are injured and need emergency assistance
Call 119 for ambulance and fire services in Japan. This is free to call. Increasingly, emergency dispatchers can connect to an interpretation service for English — state "English" when the call connects.
For non-emergency medical assistance, the JNTO Tourist Helpline (050-3816-2787, 24/7) can direct you to hospitals in your area with English-language support or help you contact your insurer's emergency line.
Before you go: checklist
- Locate the exclusions section of your travel insurance policy — search for "earthquake," "natural disaster," "force majeure"
- If any of these appear in the exclusions, contact your insurer to add a natural disaster or Acts of God rider before departure
- Confirm your medical coverage limit is sufficient for at least one week of hospitalised care in Japan
- Check whether flight cancellation coverage explicitly includes natural disaster as a covered reason
- Verify whether your insurer offers direct billing at Japanese hospitals — if so, save their 24/7 emergency number
- Download the JNTO Safety Tips app — includes a hospital search function filtered by English support

This article describes general travel insurance principles and how they typically apply to earthquake-related claims in Japan. Policy terms, coverage conditions, and exclusions vary significantly by insurer, country of purchase, and product. Always read the full policy document — not just the summary — before departure, and contact your insurer directly to confirm coverage for natural disasters.
