Sore Throat 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 difficulty breathing, cannot swallow, drooling, or a high-pitched sound when breathing.
  • If it’s not urgent: rest, fluids, and simple symptom relief usually help.
  • If you have fever/cold-like symptoms, many clinics in Japan may ask you to call ahead before visiting. Bring a mask.

Call 119 immediately (red flags)

Call 119 right away if you have any of these:

  • Difficulty breathing or you cannot swallow
  • Drooling (can be a sign you cannot swallow)
  • A high-pitched sound when breathing (stridor)
  • Severe symptoms that are getting worse quickly

What you can do right now (home care)

  • Hydrate (warm drinks can feel soothing).
  • Rest and avoid smoking/vaping.
  • Gargle with warm salt water if it helps (don’t do this for small children).
  • Use a humidifier or take a warm shower to ease dryness.
  • Avoid alcohol until you feel better.

OTC options in Japan (simple)

  • Throat lozenges or soothing throat sprays can help temporarily.
  • For pain/fever, acetaminophen (paracetamol) is often a reasonable first choice.
  • Avoid taking multiple “cold & flu” combo products at the same time (ingredient overlap).

When you should see a doctor soon

Consider medical care if:

  • Symptoms last more than about a week or keep getting worse
  • You have a very high fever, severe one-sided throat pain, or trouble opening your mouth
  • You have repeated vomiting, dehydration, or you feel unusually weak
  • You are immunocompromised or have serious chronic disease

Japan-specific: visiting a clinic

  • Many clinics ask people with fever/cold-like symptoms to call ahead and follow instructions (some may ask you to wait outside).
  • Bring a mask (commonly requested at medical facilities).

What to say (simple English)

Calling a clinic

“Hello. I have a sore throat and [fever/cough].
It started [time] ago. My temperature is [ ]°C.

At reception

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