Getting a Replacement Inhaler in Japan
If you lose your inhaler or run out of medication, you cannot purchase asthma inhalers over the counter in Japan. All prescription inhalers require a doctor's consultation and prescription (処方箋, *shohōsen*) at a licensed pharmacy (薬局, *yakkyoku*).
Common inhalers available in Japan:
Steps to get a replacement inhaler:
- Visit an internal medicine (内科) or respiratory medicine (呼吸器内科, *kokyūki naika*) clinic
- Bring your original inhaler packaging, prescription paperwork, and/or a doctor's letter
- The Japanese doctor will assess you and may prescribe an equivalent medication
- Take the prescription to a nearby pharmacy (look for the 調剤薬局 sign)
Note: Exact brand equivalents may not be available. Japanese doctors are experienced in substituting appropriate alternatives.
Treating an Asthma Attack in Japan
Mild to moderate attack (manageable with rescue inhaler):
- Use your prescribed rescue inhaler as directed
- Sit upright in a comfortable position
- Remove yourself from any trigger environment (pollution, cold air, allergens)
- Remain calm and breathe slowly
- If you have a spacer device, use it — they improve medication delivery
- If symptoms improve within 20 minutes, rest and monitor carefully
When to call emergency services (119):
Call 119 (Japan's emergency number for fire and ambulance) immediately if:
- Your rescue inhaler is not working or you do not have one
- Breathing difficulty is severe — you cannot speak in full sentences
- Lips or fingernails are turning blue (cyanosis)
- Your chest feels extremely tight and is worsening
- You are becoming drowsy or confused
- A child is not improving after initial treatment
At the emergency room:
Emergency physicians will typically administer nebulized bronchodilators (salbutamol), oral or IV corticosteroids, and oxygen if needed. Japan's emergency medicine infrastructure is excellent in major cities.
Which Department to Visit and How to Find a Clinic
- 内科 (Naika) — Internal Medicine (appropriate for adult asthma management)
- 呼吸器内科 (Kokyūki Naika) — Respiratory Medicine (specialist for chronic/complex asthma)
- アレルギー科 (Arerugi-ka) — Allergy Clinic (if pollen-related asthma during cedar season)
- 小児科 (Shonika) — Pediatrics (for children with asthma)
Use Traveler's Hospital to find English-speaking internal medicine or respiratory medicine clinics near your location in Japan.
Cost Estimate
Travel insurance with medical coverage is essential for travelers with pre-existing asthma. Ensure your policy covers asthma-related medical care in Japan, as some policies exclude pre-existing conditions without an upgrade.
Prevention: Asthma Management in Japan
During cedar pollen season (February–April):
- Check the daily pollen count (花粉情報, *kafun jōhō*) — published by the Japan Meteorological Agency
- Wear a mask outdoors; Japan sells high-filtration pollen masks (花粉症マスク) specifically for this purpose
- Keep windows closed; use air conditioning with filters
- Take a shower and change clothes after returning indoors from outdoor activities
- Consider consulting an allergist about starting antihistamines or nasal corticosteroids before your trip
General asthma management while traveling:
- Always carry your rescue inhaler in an easily accessible location
- Identify the nearest hospital or clinic to each accommodation before you need it
- Avoid smoking areas — Japan, while improving, still has more public smoking than many Western countries
- Note that some onsen (hot spring) environments have strong sulfur smells that may trigger sensitive airways

Frequently Asked Questions
Q: Can I bring my asthma inhaler to Japan?
A: Yes. Personal supplies of asthma inhalers (rescue, preventer, and combination types) are permitted entry into Japan without special import approval. Bring your prescription documentation and keep inhalers in original packaging. A general guideline is up to a 2-month personal supply.
Q: Is Japan a bad destination for asthma sufferers?
A: Japan is generally manageable for asthma travelers, but cedar pollen season (February–April) is particularly challenging for those with allergic asthma. Summer heat and humidity can also trigger exercise-induced asthma. With proper preparation, most asthma travelers have no major issues.
Q: What if I need a nebulizer treatment in Japan?
A: Nebulizer treatments (ネブライザー治療) are widely available at clinics and hospitals. If you are experiencing moderate respiratory distress, an internal medicine or emergency clinic can provide nebulized bronchodilator treatment quickly.
Q: Are Japanese generic inhalers as effective as my brand-name inhaler at home?
A: Japanese-branded inhalers contain the same active pharmaceutical ingredients as their international equivalents. A Japanese doctor can prescribe an appropriate equivalent. If you have concerns, showing the doctor your original inhaler packaging helps them identify the best match.
Q: Can I buy an inhaler over the counter at a Japanese pharmacy?
A: No. All inhalers in Japan require a doctor's prescription. Unlike some countries where salbutamol inhalers are available OTC, Japan requires a medical consultation. This is why carrying enough supply from home is strongly recommended.
Q: What should I do if I have a severe asthma attack in Japan and can't speak Japanese?
A: Call 119 immediately — Japan's emergency dispatch can connect you with English-language support. You can also simply say "asthma" (アスマ or 喘息/*zensoku*) and "help" (助けてください / *tasukete kudasai*). Emergency paramedics are trained to handle respiratory emergencies regardless of language barriers.
