• Falls on stairs and uneven surfaces. Temple and shrine steps, polished wooden floors at traditional sites, and narrow alley curbs cause many sprained ankles, twisted knees, and minor wrist injuries every year.
• Onsen and bathhouse burns. Hot spring water can exceed 42°C (107°F). Test temperature with a wrist or foot first; never enter quickly. Tile floors are also slippery — falls in the changing area are a common minor injury.
• Bicycle accidents. Many tourist towns rent bicycles. Japanese cycling rules require sidewalk caution and lights at night; collisions with pedestrians on crowded sidewalks are a frequent source of minor cuts and bruising.
• Hiking injuries. Mount Fuji and other popular routes produce sprains, dehydration, and altitude-related issues every summer. Wear proper boots and check weather forecasts; sudden changes are common.
• Ski and snowboard injuries. Niseko, Hakuba, and other resorts see thousands of foreign visitors per season. Wrist fractures, knee ligament tears, and concussions are the most common injuries presenting at resort clinics.
• Cuts from kitchenware or glass. Common in self-catering apartments and at izakaya. For deep cuts that will not stop bleeding with pressure, see a doctor for stitches.
• Traffic accidents as a pedestrian. Japanese drivers generally yield, but foreign visitors are especially prone to looking the wrong way at intersections. Always check both directions twice.

Call 119 (Ambulance) for:

• Loss of consciousness, even briefly, after a fall or impact.
• Severe bleeding that does not slow with firm pressure.
• Open fractures (bone visible) or visibly deformed limbs.
• Suspected spinal injury — do not move the person; wait for paramedics.
• Severe head injury with vomiting, confusion, or worsening drowsiness.
• Major chemical or electrical burns.

Go to a Hospital (yourself or by taxi) for:

• Suspected fractures with severe pain but no obvious deformity.
• Deep cuts that may need stitches.
• Injuries that occurred more than a few hours ago and have not improved.
• Burns larger than the palm of your hand or in sensitive locations (face, hands, feet, genitals).

See a Clinic for:

• Mild to moderate sprains with swelling but no severe deformity.
• Small cuts that have stopped bleeding but may be infected.
• Bruising and muscle strains that are not improving after 2–3 days.
• Minor burns that are red but not blistered.

• Sprains and minor strains. Diagnosed clinically, often with X-ray to rule out fractures. Treated with compression bandages, anti-inflammatory medication, and rest advice.
• Small cuts requiring stitches. Most clinics can suture cuts that are clean and recent. For deep cuts on the face or near joints, a hospital is preferable for cosmetic and functional reasons.
• Minor burns. First-degree burns and small second-degree burns can usually be treated at a clinic with topical agents and dressings.
• Mild head bumps without warning signs. A clinic visit for advice and pain management is appropriate. If symptoms develop later (vomiting, severe headache, drowsiness), proceed to a hospital.

• Take the recommended rest period seriously. Sprains and bruises that get aggravated heal much more slowly. Adjust your itinerary rather than pushing through pain.
• Use Japanese taxis and trains liberally. Both are inexpensive compared to many countries, and many train stations now have full elevator access. Avoid stairs while you heal.
• Ask the hotel front desk for help. Hotels can arrange ice, extra pillows for elevation, ground-floor rooms, and information on nearby clinics for follow-up visits.
• Confirm fitness to fly before your flight. Some injuries (recent surgery, plaster casts longer than the lower leg) require airline approval. Ask the doctor for a fit-to-fly certificate if needed; airlines may otherwise deny boarding.
• Plan follow-up care at home. Bring all medical paperwork home; a copy of imaging on a CD or USB is often included free of charge from Japanese hospitals on request.
