Dizziness in Japan (Vertigo / Lightheadedness): When to Call 119 + What to Do

Dizziness in Japan (Vertigo / Lightheadedness): When to Call 119 + What to Do

Last updated: 2026-03-04

“Dizziness” can mean many things: spinning (vertigo), feeling faint, unsteady walking, or the world going soft around the edges. Most cases aren’t dangerous—but the dangerous ones can look deceptively simple at first. So this page is built for one goal: don’t miss the red flags.

General information, not medical advice. If you think it could be serious, treat it as an emergency.

Quick Answer (TL;DR)

  • Call 119 now if dizziness is sudden/severe, you can’t stand without support, you faint/collapse, or you have stroke-like symptoms (face droop, arm/leg weakness, speech trouble). Tokyo emergency guidance lists “so unstable you cannot stand without support” as a “call 119 without hesitation” situation.
  • Stroke warning signs include sudden trouble walking, dizziness, loss of balance/coordination, and you should seek emergency help immediately if stroke is suspected.
  • If you’re unsure and stable, some areas offer #7119 phone advice (often Japanese-only).

30-Second Decision Box

Call an ambulance (119) now if any of these apply

  • You feel so unstable you cannot stand without support
  • Dizziness with face drooping, new arm/leg weakness, speech trouble, double vision, or vision loss (possible stroke)
  • Fainting/collapse, confusion, or “not fully conscious”
  • Sudden strong headache or sudden high fever with dizziness
  • Dizziness with chest tightness/pressure or difficulty breathing
  • Dizziness after a recent head injury (especially within the last 2 days)
  • You have diabetes and dizziness feels like low sugar / you’re sweaty, confused, shaky

If you’re in a hotel, ask the front desk to call 119 and guide the ambulance.

Not sure (mild symptoms, stable, able to talk/walk)?

  • Consider #7119 (availability varies; often Japanese-only).
  • Or use JNTO’s medical institution search to find appropriate care.

Step 1 — How to call 119 (Japan)

When you call 119, say:

  • “Medical emergency.”
  • Your location (hotel name / landmark / address)
  • “Dizziness / can’t stand / possible stroke” (whichever fits)

Japan’s Fire and Disaster Management Agency explains the dispatcher will ask what happened and your location; answer slowly and clearly (Learn more).

What to say (copy-paste)

  • “Medical emergency.”
  • “I’m dizzy and cannot stand.”
  • “Sudden dizziness with slurred speech / weakness / face drooping.”
  • “My location is: [hotel name / landmark / address].”

Step 2 — What to do while waiting (safe actions)

These are low-risk steps that help whether it’s vertigo, low blood pressure, dehydration, or anxiety:

  1. Sit or lie down immediately to prevent falls.
  2. Do not walk unassisted if you feel unstable.
  3. Sip water if you’re alert and not nauseated (small sips).
  4. If it’s hot/humid and you feel dizzy: move to a cool place, loosen clothing, cool your body—Japan’s EMS guidance lists dizziness as a heat illness symptom and recommends cooling and hydration if possible.
  5. If you have diabetes and suspect low blood sugar: follow your usual hypoglycemia plan (if you’re conscious and can swallow safely).

Do not drive. Dizziness + driving is how small problems become disasters.

Step 3 — When dizziness should be treated as “possible stroke”

Don’t try to self-diagnose. If dizziness is sudden and comes with balance trouble, weakness, speech/vision changes, treat it like stroke until proven otherwise. Stroke warnings explicitly include “sudden trouble walking, dizziness, loss of balance or coordination.”

Step 4 — If symptoms are not severe but still concerning

Seek same-day medical advice if:

  • dizziness keeps coming back, won’t go away, or disrupts normal life
  • you have hearing/speech issues, tinnitus, double/blurred vision, numbness/weakness, fainting/collapse, pulse changes, headache, or vomiting

These are listed as reasons to seek medical evaluation in major clinical guidance.

Tokyo’s EMS Guide also flags dizziness alongside conditions like fever, diabetes, recent injury, or hearing problems as important context.

Help lines and navigation (Japan)

  • #7119 (some areas): “unsure ambulance vs hospital” consultation; often Japanese-only.
  • JNTO medical institution search (English): find appropriate care.
  • Japan Visitor Hotline (JNTO): 24/7 multilingual support is widely listed as available at 050-3816-2787.
