Treatment in Japan
There is no specific antiviral treatment for HFMD. Japanese pediatric care focuses on symptom management and preventing dehydration — the primary serious complication in young children who refuse to drink due to mouth pain.
Managing mouth pain:
- Cold foods and drinks (yogurt, cold water, popsicles) can soothe ulcers and encourage fluid intake
- Avoid acidic, spicy, or salty foods that irritate sores
- A pediatrician may prescribe a topical oral anesthetic (口腔内軟膏, *koukounai nanko*) in severe cases
Fever management:
- Acetaminophen (アセトアミノフェン) suppositories or syrup appropriate for the child's weight
- Ibuprofen is available but not recommended for infants under 6 months
- Japanese pharmacies sell children's fever reducers; ask the pharmacist (薬剤師, *yakuzaishi*) for help finding the right product
Preventing dehydration:
- Oral rehydration solution (ORS/経口補水液) such as OS-1 in child-appropriate amounts
- Small, frequent sips are better than large volumes
- Monitor urine output (wet diapers or toilet visits) as an indicator of hydration
When to seek emergency care:
Return to a clinic or go to an emergency room immediately if your child develops: high fever lasting more than 3 days, severe headache or neck stiffness, unusual drowsiness or difficulty waking, seizures, trouble breathing, blue lips or fingernails, or an inability to drink any fluids for more than 8 hours.
Which Department to Visit and How to Find a Clinic
- 小児科 (Shonika) — Pediatrics: always the first choice for children with HFMD
- 皮膚科 (Hifuka) — Dermatology: if skin rash is the primary concern and the child is older
- 救急外来 (Kyūkyū gairai) — Emergency department: for severe or rapidly worsening symptoms
Japanese pediatric clinics are busy during summer. It is advisable to call ahead before visiting, as some clinics ask fever/rash patients to arrive during specific hours or wait in separate areas. Bring your child's age, weight, and any medications they are currently taking.

Cost Estimate
HFMD treatment is almost entirely supportive and does not typically require expensive diagnostics or hospitalization for mild-to-moderate cases. Budget approximately ¥5,000–¥10,000 per clinic visit without insurance. Travel insurance will cover these costs — always obtain receipts and ask for a clinical summary (診断書, *shindansho*) for insurance claims.
Prevention Tips
HFMD is highly contagious and can be difficult to avoid entirely in summer travel with young children, but these measures help:
- Handwashing is the single most effective prevention — after toilet use, before eating, after contact with sick children
- Avoid sharing cups, utensils, or towels with other children
- Disinfect toys and surfaces with household bleach solution (alcohol alone may not kill enteroviruses)
- Keep children away from visibly sick peers at swimming pools, playgrounds, and indoor play areas
- Note that Japan's EV-A71 vaccine is not yet available domestically (it is available in China); no vaccine is currently available for tourists
Daycare and School Exclusion in Japan
Japanese daycare centers (保育園, *hoikuen*) and kindergartens have specific rules about HFMD exclusion. Unlike some conditions, Japan does not have a legally mandated exclusion period for HFMD, but most facilities require children to remain home until:
- Fever has resolved
- Mouth sores have healed enough for the child to eat and drink normally
- Blisters have crusted over
Parents visiting Japan for longer trips should be aware that even mild HFMD may result in a child being sent home from hotel childcare facilities or tour group activities.

Frequently Asked Questions
Q: Is hand, foot and mouth disease dangerous in Japan?
A: For most children, HFMD is a mild illness that resolves on its own within a week. Serious complications including viral meningitis and encephalitis are rare but possible, particularly with EV-A71 strains. Monitoring your child's condition carefully and seeking medical care for any alarming symptoms is the appropriate approach.
Q: Can adults get hand, foot and mouth disease in Japan?
A: Yes, though it is less common. Adults who contract HFMD typically experience milder symptoms — sometimes only a rash without fever — but can still be contagious and should practice good hygiene. Adults with weakened immune systems or who are pregnant should be particularly cautious about exposure.
Q: How long is HFMD contagious?
A: HFMD is most contagious during the first week of illness, but the virus can be shed in stool for weeks after recovery. Strict handwashing is important even after visible symptoms have resolved.
Q: My child has HFMD — can we still travel within Japan?
A: It is strongly recommended that you limit your child's contact with other children while symptomatic. Avoid public indoor spaces, crowded attractions, and public pools. Most children can travel comfortably by the time their fever resolves and sores begin healing (usually 5–7 days), but use your judgment based on your child's condition.
Q: Is there an HFMD vaccine available to tourists visiting Japan?
A: No HFMD vaccine is currently available in Japan or most Western countries. An EV-A71 vaccine is available in China but is not approved in Japan.
Q: My child just got HFMD — should I cancel our entire Japan trip?
A: Not necessarily. HFMD is a self-limiting illness for most children. If your child is mildly affected and you can ensure adequate rest, hydration, and separation from other children, you may be able to continue your trip with modified plans. However, if your child is very young (under 1 year), has a high fever, or is showing any warning signs, prioritize rest and medical evaluation over sightseeing.
