If Your Kid Gets Sick in Japan: Clinics, Night Care, and What It Costs

A fever at 11 p.m. in a hotel room is stressful anywhere. In a country where you can’t read the medicine box, it’s worse. The good news: Japan has phone lines for exactly this moment, some of them in English, and walk-in children’s clinics are normal here.

The problem is that the best services are documented mostly in Japanese, and each one has its own hours and languages. This guide puts them in one place, sorted by what time it is and what language you need.

Quick answer: who to call

If it’s an emergency (trouble breathing, unconscious, a seizure that won’t stop): call 119. It’s the ambulance number nationwide, and for callers who don’t speak Japanese, the Tokyo Fire Department connects a three-way interpreter in English, Chinese, Korean, Portuguese or Spanish. Stay on the line while it connects.

For everything else in Tokyo:

The two Japanese-only lines (#7119 and #8000) are the ones Japanese parents use. If your hotel has a 24-hour front desk, it’s reasonable to ask the staff to call for you and translate.

The phone lines, one by one

Himawari foreign-language line (Tokyo): your daytime first call

Tokyo’s official medical information service runs a foreign-language line at 03-5285-8181, every day from 9 a.m. to 8 p.m., in English, Chinese, Korean, Thai and Spanish. The consultation is free; you pay only for the call.

They can:

• tell you which nearby clinics and hospitals can see you in a foreign language,
• explain how Japanese medical care works,
• give you an idea of costs if you have no Japanese insurance, and
• help with interpretation in an emergency.

Tokyo Metropolitan Government: Himawari

Himawari also has a Japanese-language line, 03-5272-0303, open 24 hours, which tells you which medical institutions near you are accepting patients right now. If a Japanese speaker is with you (or the hotel desk will help), this is the line for “which hospital is open at 2 a.m.?”

Japan Visitor Hotline (JNTO): the 24-hour English option

The Japan National Tourism Organization runs 050-3816-2787, 24 hours a day, 365 days a year, in English, Chinese and Korean. It’s made for visitors, and it covers emergencies such as illness and disasters as well as ordinary tourist questions. After Himawari’s foreign-language line closes at 8 p.m., this is the English-language number to save. Tokyo Metropolitan Government: Japan Visitor Hotline

#7119: “Should we call an ambulance?”

The Tokyo Fire Department’s Emergency Consultation Center answers 24 hours a day. A team of doctors, nurses and former paramedics judges how urgent the symptoms sound and tells you which medical institutions can see you at that hour. Dial #7119 from a mobile phone, or 03-3212-2323 (central Tokyo, the 23 wards) if that doesn’t connect. They don’t handle questions about medicine or general health. They also ask you to phone the hospital before you go. Tokyo Fire Department Q&A (Japanese)

The center works in Japanese. An older Tokyo government overview says foreign-language callers during Himawari’s hours (9 a.m.–8 p.m.) are passed to Himawari. Outside those hours, plan on a Japanese speaker, or use the JNTO hotline instead.

#8000: the parents’ night line

#8000 is the number Japanese parents call when a child is sick at night. In Tokyo, nurses and public health nurses answer, with pediatricians stepping in when needed. It’s advice by phone, not a diagnosis. Hours: weekdays 6 p.m. to 8 a.m.; weekends, holidays and New Year 8 a.m. to 8 a.m. the next day. If #8000 doesn’t work from your phone, dial 03-5285-8898.

The Tokyo page doesn’t mention foreign languages, so assume Japanese.

Finding an English-speaking pediatric clinic

Use JNTO’s search

JNTO’s medical institution search lets you filter by:

• Language (English and others)
• Department: choose Pediatrics
• Area (all 47 prefectures)
• Credit cards accepted (Visa, Mastercard, Amex, Diners, JCB, UnionPay)
• 24-hour emergency availability

You can also download a PDF list by prefecture. I’d save the list for each city on your route before you fly, so you’re not searching at night.

Tokyo has its own medical information site for visitors (launched March 2025, in English, Chinese and Korean), with a list of hospitals that accept foreign patients. Japan’s Ministry of Health also runs a nationwide search, NAVII, which can filter by language.

Clinic first, big hospital only if needed

In Japan, a small neighborhood clinic (kurinikku or iin) is the normal first stop for a feverish child. Pediatric clinics are called shōnika (小児科). Large hospitals expect a referral letter from a clinic for non-emergency visits, as Tokyo’s official guide notes.

Tokyo’s guide also says to phone or check before you go: some clinics take walk-ins, others are appointment-only. One parent on Reddit described walking into the nearest children’s clinic without a booking, and that’s common, but call first if you can. Tokyo: how a visit works

What to bring: passport, your travel insurance details, cash, any medicine your child is taking (in its packaging), and a note of their weight and when the fever started.

At night and on weekends

Tokyo runs a holiday and all-night care program in which participating hospitals keep pediatricians and children’s beds available. About 240 hospitals take part in Tokyo’s round-the-clock emergency network. You don’t pick one off a map: call #7119 or Himawari’s 24-hour line (03-5272-0303) to find out which one is open near you at that hour. Tokyo Metropolitan Government (Japanese)

Both lines are in Japanese, which is why a hotel with a 24-hour front desk is worth a lot on a family trip.

What it costs without Japanese insurance

This is the part visitors worry about, so here’s exactly what official sources say.

• You’re outside the public system. Tokyo’s guide: visitors “are not covered by Japan’s public health insurance system, resulting in the possibility of high medical costs.” JNTO adds that without travel insurance “you may be charged the full amount.”
• Each hospital sets its own price for visitors. Japan’s Ministry of Health says treatment for foreign visitors falls outside the insurance system, so each institution sets its price within the law. Some charge more than the standard insured rate: for example, Osaka Rosai Hospital charges patients without Japanese insurance twice the standard rate (¥20 per fee point instead of ¥10), plus consumption tax, since September 2025.
• Bring cash. JNTO: “payment by credit card is only accepted at major hospitals. Clinics generally accept cash only.” Tokyo’s guide says many medical institutions don’t take cards or e-money, so check before you go.
• Pay the bill. JNTO warns that visitors who don’t pay medical bills may be refused entry to Japan in future.

So what does a clinic visit cost? There’s no official per-visit price for visitors, because it varies by clinic and by what’s done. One family on Reddit reported paying about ¥16,000 (≈$101) at a walk-in children’s clinic in Tokyo (they also had travel insurance). Treat that as one family’s report, not a price list. For an estimate before you go, ask Himawari (03-5285-8181); uninsured costs are one of the topics it covers.

Ask for a receipt, and keep it with any paperwork from the clinic. Your insurer will want them for a claim.

Travel insurance: why it matters more with kids

JNTO’s guide lists real cases: a heart attack needing surgery and a 45-day hospital stay cost ¥10 million (≈$63,000); treatment for a collapsed lung after an injury came to ¥7.5 million (≈$47,500). Those are adult cases, but they show what “full amount” can mean.

For families, what to look for in a policy:

1. Medical cover for every child, including infants (check the age rules).
2. Cashless or direct billing in Japan, if available. JNTO notes that with a cashless service you don’t pay at the hospital, which matters because clinics often want cash.
3. A 24-hour assistance phone line in your language that can find a clinic for you.
4. Trip interruption cover, in case a sick child means changing flights.

Buy it before you leave home, and save the policy number and assistance number in your phone.

Pharmacies and fever reducers for kids

Two kinds of shop

• Drugstores (doraggu sutoa): sell over-the-counter medicine, diapers, baby food and snacks. Opening hours vary by store.
• Dispensing pharmacies (chōzai yakkyoku, 調剤薬局): fill prescriptions, usually near clinics. Tokyo’s guide notes that a Japanese prescription is valid for only four days, so fill it straight away.

Children’s fever reducers sold in Japan

Japanese packaging is in Japanese only, so knowing names helps. Two common children’s products, both from Lion’s Bufferin line, are listed in Japan’s official drug database (PMDA):

Sources: PMDA, Bufferin C II, PMDA, Bufferin Chewable (Japanese)

Note the age limit: neither is for children under 3. Show the staff your child’s age and weight, and ask for the pharmacist (yakuzaishi). I won’t give doses here. Follow the package and the pharmacist.

My honest tip: pack the children’s fever reducer you already use at home, plus a thermometer. You know the dose, your child knows the taste, and you won’t be reading Japanese labels at midnight. One Reddit parent’s packing list said the same: “a baby thermometer, baby paracetamol.”

Bringing your child’s medicine into Japan

Japan’s rules for medicine you carry in for your own (or your child’s) use, per the Ministry of Health:

More than that needs an import certificate (Yunyu Kakunin-sho) obtained before you travel. Since February 2023 you can apply online.

Some medicines need special permission or aren’t allowed at all:

• Narcotics (and “stimulants’ raw materials”) need permission in advance.
• Psychotropics above set amounts need a doctor’s certificate.
• Amphetamine-based ADHD medicines such as Adderall can’t be brought in, even for treatment.

If your child takes ADHD medication or anything controlled, check the Narcotics Control Department’s guidance well before your trip. MHLW rules on personal imports (Japanese)

Keep medicine in its original packaging with a copy of the prescription.

FAQ from parents

“Our 10-month-old has a fever. Can we just walk into a clinic?” Often, yes. One Reddit family did exactly that at the nearest children’s clinic. But Tokyo’s official guide says to phone or check first, because some clinics are appointment-only. In the daytime, call Himawari (03-5285-8181) and ask for a pediatric clinic near you that can communicate in English.

“How much will a doctor’s visit cost us?” Without Japanese insurance you pay the full price, and each clinic sets its own price for visitors. One family reported about ¥16,000 (≈$101). Bring cash, and ask Himawari for an estimate.

“There’s a flu outbreak. Should we cancel?” That’s your call and your doctor’s, not mine. What I can say: have travel insurance with medical cover, save the numbers in this guide, and pack your usual fever reducer and thermometer.

“Is there an English line at 2 a.m.?” Yes: the Japan Visitor Hotline, 050-3816-2787, runs 24 hours in English. For a real emergency, 119 has English interpretation.

“Can I buy children’s paracetamol in Japan?” Yes, for children 3 and up: look for 小児用バファリン (acetaminophen). For under-3s, bring your own from home and ask a pharmacist or doctor.

Before you go: sick-kid checklist

1. Buy travel insurance with medical cover for every child; save the assistance number.
2. Save these numbers: 119, Himawari 03-5285-8181, JNTO 050-3816-2787, #7119, #8000.
3. Download JNTO’s pediatric clinic list for each city on your route.
4. Pack: your children’s fever reducer, a thermometer, any prescriptions (within the 1-month limit) in original packaging.
5. Write down each child’s weight and any allergies (in Japanese if you can; see my eating-out guide for allergy cards).
6. Carry some cash, ideally ¥20,000 (≈$127) or more, for a clinic visit.
7. Pick hotels with a 24-hour front desk that can call Japanese-language lines for you.

If your bags are being forwarded between cities, keep the medicine kit in your day bag. It’s on the first-night bag list for a reason.
