Travel insurance for Japan: why it is strongly recommended, what to look for and what to do if you fall ill

Do you need travel insurance for Japan?

The Japan National Tourism Organization does not hedge: "It is strongly recommended that all travelers to Japan get travel insurance." Nothing in the entry procedure asks for a policy if you arrive visa-free, so the recommendation is easy to ignore — until you see why it is made.

Three facts from the official advice settle the question. First, illness abroad is not rare: JNTO cites a Japan Tourism Agency survey finding that "one in twenty people suffers from sickness or injuries while abroad." Second, Japan's national health insurance is for residents; a visitor is billed the full cost of treatment, and the Japan Tourism Agency warns that those costs "can be very high" — its guide for visitors who fall ill gives examples of about 7.5 million yen for a collapsed lung with fractured ribs and 10 million yen for a heart attack. Third, the bill follows you home: JNTO notes that "since 2021, foreigners who have unpaid medical expense in Japan may be restricted or refused entry to Japan."

Set against a trip that already costs a few thousand dollars, a policy that caps your exposure at a known premium is not a luxury. It is the cheapest part of the trip.

What medical care costs in Japan

Visitors are not covered by Japan's health insurance system, so the hospital bills the whole cost of treatment. The Japan Tourism Agency's guide for visitors who fall ill illustrates the scale with two cases — pneumothorax with fractured ribs at roughly 7.5 million yen, and a heart attack at 10 million yen — which is why its insurance advice talks about "coverage of up to 10 million yen that even covers expensive treatment". A sprained ankle or a bout of food poisoning costs a small fraction of that, but it still means a consultation, tests and medicine paid for on the day.

Two practical complications make insurance worth more than its payout. JNTO points out that some clinics do not accept credit cards, so without cover you may need a good deal of cash at exactly the wrong moment. And a hospital is one of the few places in Japan where English cannot be relied on; a policy with an assistance line that interprets and arranges a hospital for you solves a problem that money alone does not.

What a Japan policy should include

Compare policies on these points rather than on price alone:

1. Medical expenses of at least 10 million yen. That is the figure the Japan Tourism Agency uses when it describes adequate cover, and it matches its own worst-case examples. A limit set in your home currency should convert to at least that.
2. Cashless hospital payment. JNTO explains the term: with a cashless service the insurer pays the medical provider directly, so you are not asked to find the money first and claim it back later. Policies without it still pay — but you front the bill.
3. A 24-hour assistance line with interpretation and hospital referral. JNTO's emergency guide lists "interpretation services as well as medical institution referral and arrangement services" among the things that matter. Check that the number works from a foreign mobile.
4. Trip cancellation and interruption, so that a cancelled flight or a family emergency at home does not cost you the hotels and rail passes you prepaid. A Japan Rail Pass, for example, can only be refunded before its start date.
5. Baggage and personal belongings, including the phone that holds your tickets.
6. Personal liability, which pays if you injure someone or damage property — relevant if you plan to drive, cycle or ski.
7. The activities you actually intend to do. Skiing, snowboarding, scuba diving, cycling tours and motorbike hire are commonly excluded unless added.
8. Pre-existing conditions declared. An undeclared condition is the most common reason a medical claim is refused.

Can you buy travel insurance after arriving in Japan?

Yes. JNTO's travel-insurance page notes that insurance can be purchased after arrival, and its emergency guide says that "private medical insurance can be purchased instantly online" — a product designed for visitors who are already in the country, with "coverage of up to 10 million yen that even covers expensive treatment", interpretation and hospital-referral services, and "negotiation of cashless payment for medical expenses". The JNTO emergency pages link to the current provider; this site does not sell or rank policies.

This is the fallback, not the plan. A policy bought after landing covers what happens from then on; it cannot cover a flight already cancelled, luggage already lost, or an illness that has already started. Buy before you fly, and treat the post-arrival option as a repair for a forgotten policy or one that turns out to be inadequate.

If you fall ill in Japan: what to do, step by step

When it is not an emergency

1. Find a clinic or hospital that handles foreign patients. The medical-institution search on JNTO's emergency site (linked under Sources) lists hospitals and clinics by area, language and speciality. Your insurer's assistance line can do the same and may arrange a cashless admission directly.
2. Go during regular hours. The official advice is to "visit a clinic or general hospital during regular hours"; after-hours reception exists but "varies by region", and a late-night visit usually means a larger hospital and a longer wait.
3. Take your passport, your insurance certificate and any medicine you take. The same guide publishes two printable sheets for the visit — "Personal information concerning medical care" and a "Sheet for pointing to symptoms" — which get you through reception and the first questions without a shared language.
4. Pay and keep every receipt if the insurer is not paying the hospital directly; you will need them to claim.

In an emergency: how to call an ambulance

Dial 119 from any phone — mobile, landline or public phone. The Fire and Disaster Management Agency's English guide states that "the ambulance service is available for anyone in Japan", and sets out what the dispatcher will ask, in order:

• Say that it is a medical emergency (the same number also serves fire).
• Give the location. If you do not know the address, "describe a nearby building or intersection as a landmark."
• Describe the symptoms and when they started, and give the patient's age — or roughly how old they look.
• Give your name and a phone number that will work after the call ends, because the crew may ring back if they cannot find you.

The guide adds that "if the situation is serious, the ambulance will be dispatched before all these questions have been asked", and that you should ask a Japanese speaker nearby to help with the call if there is one.

While you wait, the same guide suggests having three things ready: your passport, cash or a credit card to pay at the hospital, and the medicine you normally take. If other people are with you, send someone out to where the ambulance will pull up so the crew finds you faster. When it arrives, tell the team how the illness or accident happened, what changed before they got there, the most painful symptom, past illnesses and current medication — a note of your medical history in your wallet does most of this for you.

Numbers to keep in your phone

Earthquakes, typhoons and heat

Insurance is only part of being prepared. Japan has earthquakes every year, typhoons in late summer and early autumn, and summers hot enough that, according to the Fire and Disaster Management Agency, more than 40,000 people a year are taken to hospital by ambulance for heat stroke. JNTO's advice for a large earthquake is simple: if you are indoors, "stay calm and follow any instructions staff might give"; check the evacuation routes at your hotel when you check in; and "if you are by the coast when a large earthquake strikes, head for higher ground in case of a tsunami". For warnings and emergency news in English, JNTO points to the Japan Safe Travel information service, the Safety Tips app and NHK WORLD-JAPAN — install the app before you leave.
