Cough in Japan: What to do (and when to call 119)

Last updated: 2026-03-03

TL;DR (30-second decision)

  • Call 119 now if you have trouble breathing, blue lips, severe chest pain, you can’t speak in full sentences, you are confused/fainting, or you cough up a lot of blood. (mayoclinic.org)
  • If you’re unsure whether it’s an emergency: Call #7119 (if available).
  • If you have cough with fever/cold-like symptoms, many clinics in Japan ask you to call ahead and follow special instructions; bring a mask. (kuas.ac.jp)
  • Most mild coughs improve with rest, fluids, and time.

Call 119 immediately (red flags)

Call 119 right away if you have any of these:

  • Trouble breathing or severe wheezing, blue lips/face
  • Severe chest pain or you feel you cannot get enough air
  • You are confused, fainting, or extremely weak
  • Coughing up a lot of blood, or blood with serious symptoms
  • You may be choking, or you inhaled vomit and now can’t breathe well
  • Sudden severe allergic reaction signs (swelling, throat tightness, wheezing)

If it’s not clearly urgent: what you can do right now

  • Hydrate (warm drinks can feel soothing).
  • Rest and avoid smoking/vaping.
  • Keep the room comfortably humid (a humidifier or a warm shower can help some people).
  • If your throat is irritated, honey/lemon drinks may help (not for infants).
  • If you have asthma, use your prescribed inhaler as directed.

OTC medicines in Japan (quick guide)

OTC cough medicines vary a lot, and some cause drowsiness.

A simple safe approach

  • Start with non-drug measures (fluids, rest, humid air).
  • Ask a pharmacist for a product that matches your symptom:
    • “dry cough” vs “cough with mucus (phlegm)”
    • nighttime cough vs daytime cough

Avoid “stacking” multiple cold medicines
Many combo products overlap ingredients. Use one product and follow the label.

When you should see a doctor soon

Consider medical care if:

  • Cough lasts more than 2–3 weeks, or keeps getting worse
  • You have fever that persists, or you feel very unwell
  • You have shortness of breath, chest pain, or wheezing (even if not severe)
  • You cough up blood (even small amounts should be medically evaluated)
  • You are older, immunocompromised, pregnant, or have serious chronic disease

Japan-specific: visiting a clinic when you have cough/fever

This is important in Japan:

  • Many clinics ask patients with fever or cold-like symptoms (cough/sore throat) to call ahead before visiting.
  • Some clinics may ask you to wait outside, use a separate entrance, or follow infection-control procedures.
  • Bring a mask—many medical facilities request it.

What to say (simple English)

Calling a clinic

“Hello. I have a cough and [fever/sore throat].
It started [time] ago. My temperature is [ ]°C.
Can I visit today? Do I need an appointment?”

At reception

“I have a cough.”
“I called ahead.” / “Do I need to wait outside?”

If you’re worried and not sure (calling #7119)

“I have a cough and I’m worried about my breathing.
Do I need an ambulance? Where should I go?”
