Pollen Allergy in Japan

In Japan, pollen dispersion peaks from February to April,
and most people have symptoms caused mainly by pollen from cedar and cypress.
Preventive treatment can reduce symptoms during that terms.
It is also important to get appropriate diagnosis and treatment, so please feel free to consult us.


Hay fever symptoms usually start immediately after you’re exposed to a specific allergy-causing substance (allergen) and can include:
・ Runny nose and nasal congestion
・ Watery or itchy eyes
・ Sneezing and Coughing
・ Itchy nose, roof of mouth or throat
・ Sinus pressure and facial pain
・ Swollen, blue-colored skin under the eyes (allergic shiners)
・ Decreased sense of smell or taste
Your hay fever symptoms may start or worsen at a particular time of year, triggered by tree pollen, grasses or weeds, which all bloom at different times.
If you’re sensitive to indoor allergens, such as dust mites, cockroaches, mold or pet dander, you may have year-round symptoms.

Is it hay fever? Or is it a cold?

Signs and symptoms can be different.
Here’s how to tell which one’s causing your symptoms:

  Hay Fever Colds
Signs and symptoms Runny nose with thin, watery discharge; no fever Runny nose with watery or thick yellow discharge; body aches; low-grade
Onset Immediately after exposure to allergens One to three days after exposure to a cold virus
Duration As long as you’re exposed to allergens Five to seven days

If your symptom seems to be hay fever, we reccomend that you visit an ophthalmologist, because we can prescribe more various kinds of eye drops than otorhinolaryngologists.


When to see a doctor

See your doctor if:
・ You think you may have hay fever
・ Your symptoms are ongoing and bothersome
・ Allergy medications aren’t working for you
・ Allergy medications work, but side effects are a problem
