Hay fever countermeasures have a clear priority order: prescription medication first, then masks and pollen glasses, then indoor measures. Follow the right order and symptoms can be kept well under control. This article covers prioritized countermeasures, products available in Japan, how to visit a hospital, and a pre-season checklist.
For the basics on how hay fever works and its symptoms, see What Is Hay Fever?. For Japan-specific pollen details, see Why Japan's Pollen Is So Bad.
What's the Priority Order?
There are many hay fever countermeasures, but you don't need to do everything at once. Start with the most effective options first.
- Countermeasure
- See a doctor → take prescription meds
- Expected effect
- Significantly reduces symptoms
- Countermeasure
- OTC antihistamines (Allegra, Claritin, etc.)
- Expected effect
- Less effective than prescriptions but accessible and fast-acting
- Countermeasure
- Masks + pollen glasses for physical blocking
- Expected effect
- Reduces pollen entering your body
- Countermeasure
- Indoor measures (ventilation, laundry, air purifier)
- Expected effect
- Reduces symptoms at home
| Priority | Countermeasure | Expected effect |
|---|---|---|
| 1️⃣ Top | See a doctor → take prescription meds | Significantly reduces symptoms |
| 2️⃣ High | OTC antihistamines (Allegra, Claritin, etc.) | Less effective than prescriptions but accessible and fast-acting |
| 3️⃣ Medium | Masks + pollen glasses for physical blocking | Reduces pollen entering your body |
| 4️⃣ Supplementary | Indoor measures (ventilation, laundry, air purifier) | Reduces symptoms at home |
📌 Bottom line: If your symptoms are more than mild, seeing a doctor is the fastest path to relief — faster than trying to power through with products alone. Japanese ENT clinics and allergy departments are very experienced with hay fever. With health insurance, a visit plus medication typically costs around ¥2,000–3,000 (varies by insurance type and medication).
In my case, I initially tried to get by on OTC medicine alone, but during cypress season, OTC wasn't enough. Going to a doctor and getting prescription medication made a dramatic difference. With insurance, prescriptions often end up cheaper than OTC — so it's better value in the long run.
What Products Can You Buy in Japan?
Here's a category-by-category guide to hay fever products available at drugstores and convenience stores.
Masks
Pollen enters through the mucous membranes of your nose and mouth, so blocking it with a mask is a fundamental countermeasure. Japanese drugstores carry an extensive selection of pollen-specific masks. Look for packaging that says "花粉" (kafun) or "99% cut."
- 📌 Masks come in "regular" and "small" sizes — choosing the right fit minimizes gaps and improves effectiveness
- 💰 Around ¥300–500 for a pack of 30

Pollen Glasses
If itchy eyes are a major problem, pollen glasses are a great option. Pollen sticks to the mucous membranes of your eyes, causing itchiness and redness, so glasses that cover around the eyes physically reduce pollen exposure.
- 📌 Regular glasses or sunglasses also provide some protection
- 💰 Around ¥1,000–3,000 (available at drugstores and optical shops)

Nasal Spray & Eye Drops
Pharmacies carry nasal sprays and eye drops labeled "花粉症用" (for hay fever). These act directly on mucous membranes, locally suppressing inflammation and allergic reactions.
- 📌 Nasal sprays include steroid-based and antihistamine types that reduce nasal inflammation and congestion. Note that vasoconstrictor-type nasal sprays can backfire with prolonged use — watch the recommended duration
- 📌 Eye drops with "抗ヒスタミン" (antihistamine) are designed for hay fever. They block histamine directly on the eye's mucous membrane, relieving itchiness and redness

Oral Medication (OTC Antihistamines)
When pollen enters your body, the immune response releases histamine, causing sneezing, runny nose, and itchy eyes. Antihistamines suppress histamine from the inside, reducing symptoms throughout your body.
Here are common OTC hay fever medications available in Japan. Effects and side effects vary by individual, so consult a pharmacist if unsure.

What Can You Do Indoors?
Taking hay fever precautions at home makes a noticeable difference in symptoms after you get home.
- ✅ Brush off clothes at the door — Shake pollen off your jacket before entering the house
- ✅ Ventilate briefly, through lace curtains — Don't open windows wide. Ventilate during early morning or rainy periods when pollen counts are low
- ✅ Dry laundry indoors — Avoid hanging laundry outside during pollen season. Switch to bathroom drying or indoor drying racks
- ✅ Use an air purifier — HEPA filter models are effective. Placing one in the bedroom helps with symptoms while sleeping
- ✅ Shower after coming home — Rinse pollen off your hair and skin

How Do You See a Doctor? A Guide for Foreigners
Here's the basic process for visiting a hospital for hay fever.
Which Department?
- Internal medicine (naika) — The most accessible and numerous option. Many clinics handle hay fever diagnosis and prescriptions, and it's an easy first stop
- ENT / Otorhinolaryngology (jibi-inko-ka) — For severe runny nose or nasal congestion, you can get specialized examination
- Allergy department (arerugi-ka) — For comprehensive hay fever care. Also the place to go for allergy testing or sublingual immunotherapy
- Ophthalmology (ganka) — For severe eye itchiness or redness
Do You Need an Appointment?
It varies by clinic, but many ENT clinics accept walk-in patients. However, clinics tend to be busy during pollen season, so checking online reservations or Google Maps reviews for wait times beforehand makes things smoother.
Can You Use Insurance?
- ✅ If enrolled in National Health Insurance or employer-based insurance: 30% copay. Typically around ¥2,000–3,000 for consultation plus medication
- ❌ Without insurance (e.g., tourists): Full cost out of pocket. Check if your travel insurance covers it beforehand
How to Find English-Speaking Hospitals
If you're not confident in Japanese, try these methods to find English-friendly clinics:
- JNTO Medical Institution Search
- Search Google Maps for "English speaking clinic"
- Contact your local international exchange association
📌 Even if you can't find an English-speaking clinic, saying "kafunsho" (花粉症) is usually enough for the doctor to understand. For Japanese medical terms you might need, see the vocabulary section in What Is Hay Fever?.
Pre-Season Checklist
Preparing before pollen season starts helps keep symptoms milder.
- 📄 By January: Check that year's pollen forecast (Hanako-san, tenki.jp)
- 📄 Jan–Feb: If last year was rough, visit an ENT clinic 2–4 weeks before pollen season starts and discuss "initial therapy" (shoki ryoho)
- 📄 By early February: Stock up on masks, pollen glasses, and eye drops
- 📄 During the season: Check daily pollen forecasts and reduce outdoor time or strengthen precautions on high-pollen days
FAQ
OTC or prescription — which is better?
If symptoms are mild, OTC may be enough. But if OTC doesn't work, symptoms are severe, or you suffer for months every year, prescription medication offers a wider range of options tailored to your symptoms. Japanese doctors are very experienced with hay fever, so don't hesitate to visit.
What should I say at the hospital?
Saying "kafunsho da to omoimasu" (花粉症だと思います / I think I have hay fever) is enough. The doctor will ask about your symptoms from there. Even without Japanese, gestures for sneezing, blowing your nose, or rubbing your eyes get the point across. Translation apps on your smartphone also work well.
What symptoms does hay fever cause?
The most common symptoms are repeated sneezing, clear watery runny nose, nasal congestion, and itchy/red eyes. Some people also experience throat itchiness, skin dryness/irritation, and general fatigue or difficulty concentrating.
