Allergies in Japan – Medical Care for Tourists

Allergic reactions can happen unexpectedly — a new food, a burst of pollen, a detergent, or an insect bite. This guide covers what to do for common allergies, when to seek urgent care, and where to find help as a visitor.

Types of Allergic Reaction

Seasonal allergies (hay fever / kafunsho). Cedar pollen in spring is particularly strong in Japan.
Food allergies. Japanese cuisine uses ingredients (soy, wheat, eggs, shellfish, buckwheat) that may be hidden in dishes.
Skin reactions. Hives, rashes, or contact dermatitis from soaps, cosmetics, or fabrics.
Insect bites and stings. Mosquito bites, bee stings, and occasional encounters with centipedes.
Anaphylaxis. A severe, life-threatening reaction involving breathing difficulty or swelling of the mouth and throat.

Emergency: Anaphylaxis

If you or someone with you shows signs of a severe allergic reaction — difficulty breathing, swelling of the face or throat, dizziness, or collapse — act immediately:

Call 119 for an ambulance.
If you have an epinephrine auto-injector (EpiPen), use it as prescribed.
Keep the person lying down with legs raised, or sitting up if breathing is difficult.
Do not give food or drink.

Bring any known allergen information and medication packaging with you to the hospital.

Over-the-Counter Options

Japanese drugstores carry several antihistamines suitable for mild allergies:

Allegra, Claritin, Stonac — common non-drowsy antihistamine tablets.
Eye drops (mekusuri) for itchy eyes during pollen season.
Topical creams for hives and contact dermatitis.
Masks — widely available to reduce pollen exposure.

Tell the pharmacist if you’re already taking medication; many antihistamines can interact with other drugs.

Finding a Doctor

For more severe or persistent reactions, an internal medicine (naika) clinic or allergy specialist (arerugi-ka) can evaluate your symptoms and prescribe stronger medication if needed.

Online Consultation Option

If you’d rather not travel while feeling unwell, online consultations with doctors are increasingly available in Japan and are well suited to non-urgent symptoms. A doctor can assess your situation remotely and recommend next steps.

Frequently Asked Questions

Q. Can I get an EpiPen in Japan?

Epinephrine auto-injectors are available by prescription in Japan. If you already carry one, bring it with you — replacing one locally requires seeing a doctor.

Q. What if I don’t know what caused my reaction?

A doctor can help identify likely triggers. Bring photos of food labels, cosmetics, or places you’ve been shortly before symptoms started.

Q. Are Japanese food labels reliable for allergens?

Japan has legal labeling requirements for common allergens in packaged food. Restaurants are less standardized — ask staff directly, using a translation card if needed.

Q. Will travel insurance cover allergy treatment?

Most policies cover unexpected allergic reactions, especially severe ones. Pre-existing allergies that flare up may have more limited coverage — check your policy.

Q. Can I fly after an allergic reaction?

Mild reactions are usually fine, but consult a doctor before flying if you’ve had a severe reaction, especially within 24 hours.
