Visitors aren't covered by Japan's public health insurance, so you pay for medical care at the time and claim it back from your travel policy afterward. Most insurers want three things: proof of what was wrong, proof of what you paid, and proof that you paid it.
In practice that means a medical certificate, an itemized receipt, and evidence of payment — all far easier to assemble on the day than to chase from another continent a fortnight later.
This guide covers the claim process end to end. If what you need is the certificate itself, our guide to medical certificates covers that document specifically; for notes aimed at an employer, school or airline, see the sick note guide.
What insurers usually ask for
| Document | What it proves |
|---|---|
| Medical certificate | The diagnosis or reason for the visit, the date, and the treating physician's name and credentials |
| Itemized receipt | What you were charged for, broken down rather than as a single total |
| Proof of payment | That you actually paid — the card statement line or payment confirmation |
| Pharmacy receipt | The medication cost, which is billed separately from the consultation |
| Your policy number and claim form | Whatever your specific insurer requires; forms differ |
Requirements vary by insurer and by policy, and no article can tell you what yours will accept. Check your policy wording or ask your insurer directly — that one phone call is what prevents a rejected claim.
Contact your insurer early
Many policies expect notification within a set window of treatment, and some require pre-authorization above a certain amount or for anything beyond routine outpatient care. Most also run a 24-hour assistance line, which is worth using before a large expense rather than after it.
If your situation is minor and you're paying a modest consultation fee, notifying afterward is usually fine. If it's escalating — a hospital admission, a changed flight, anything involving repatriation — call them first.
Get the documents in English on the day
A claim handled outside Japan will be read by someone who doesn't read Japanese. Documents issued in English from the outset skip a translation step, and skip the delay while an adjuster asks for clarification of something they can't read.
With an online consultation, an English medical certificate and an itemized English receipt are issued as part of every visit — there's no separate request or additional fee for them. If your insurer needs a particular format, a specific field, or wording about fitness to travel, say so at the start of the consultation so it can be reflected in the document.
Filing the claim
- Read your policy's medical section before you file, so you know the notification window and what's excluded.
- Collect the certificate, the itemized receipt, the pharmacy receipt, and your payment evidence in one place.
- Photograph or scan everything the day you receive it, while it's in your hand and legible.
- Complete the insurer's claim form — most have an online portal now — and attach the documents.
- Keep the originals until the claim is settled, not until you get home.
A note on expectations: a claim is decided by your insurer against your policy, and nobody else can promise an outcome. Telehealth coverage in particular varies between providers. What you can control is that the paperwork is complete, legible, in English, and submitted on time.
Why claims get delayed
Most rejected or delayed claims fail on paperwork rather than principle. The patterns are consistent and avoidable.
- A total-only receipt with no breakdown, when the insurer wants to see what was charged for.
- Documents in Japanese, which trigger a translation request and weeks of delay.
- A name spelled differently on the medical document than on the policy or passport.
- No evidence of payment — the receipt shows a charge, but nothing shows you paid it.
- Notification after the policy's deadline had already passed.
- A pre-existing condition that wasn't declared when the policy was bought.
Almost all of these are cheap to prevent on the day and expensive to fix from home. Check the spelling of your name on every document before you leave the consultation, and photograph everything immediately.
If it becomes something bigger
The process above is for ordinary outpatient care. If you're admitted to hospital, need a procedure, have to change flights, or might need to be moved home, stop and call your insurer's assistance line first. Those cases are usually handled directly between the insurer and the hospital rather than by reimbursement, and arranging it after the fact is far harder than arranging it at the time.
Keep the assistance number somewhere you can reach it without your laptop — in your phone contacts and on paper. It's the one piece of policy information worth having offline.
Will my travel insurance cover an online consultation?
That depends on your policy — telehealth is treated differently by different insurers. Check your policy wording or ask your insurer before booking if it matters to you.
Do I pay first and claim back, or does the insurer pay the clinic?
For ordinary outpatient care in Japan, you generally pay at the time and claim reimbursement afterward. Direct billing tends to apply to hospital admissions arranged through the insurer's assistance line.
What if my receipt is in Japanese?
Insurers may ask for a translation, which adds time. Documents issued in English from the outset avoid that step — ask for them at the consultation rather than afterward.
How long do I have to file?
It's set by your policy, and windows vary. Check the medical section of your policy wording, and notify the insurer sooner rather than later.
Can I claim the cost of medication too?
Medication is usually claimable where the policy covers the treatment, but it's billed and receipted separately at the pharmacy — so keep that receipt alongside the consultation one rather than assuming a single document covers both.
Should I call my insurer before or after treatment?
Before, if the situation is escalating — a hospital admission, a procedure, a changed flight, or anything that might involve being moved home. For an ordinary outpatient consultation, notifying afterward within your policy's window is usually fine.
