After a Typhoon in Japan: Floodwater, Power and Damaged Luggage

What is the safest order after a typhoon?#

The most common mistake is treating the end of strong wind as the end of the danger. Floodwater, unstable slopes, fallen wires, broken glass, and stopped transport can remain dangerous for hours or days. As of July 2026, Japan Meteorological Agency (JMA) warnings and advisories cover hazards such as heavy rain, flood, storm surge, and high waves. Check the municipality where you are, the route you need, and the destination—not just a weather app’s storm icon.

Use this order when deciding what to do:

First question	If the answer is yes	Your next action
Is there an evacuation instruction, rising water, or an unsafe building?	You may still be in danger	Follow local instructions and move to a designated safe place or higher level before routes close
Is floodwater on the road, in an underpass, station entrance, or hotel basement?	The route is not safe to inspect on foot	Turn around; ask staff for an elevated indoor route
Is there a fallen wire, sparking equipment, smoke, or a burning smell?	Electrical or fire danger may be present	Keep away and call 119 for immediate danger; do not investigate
Is the building dry but the power is out?	The outage may be storm-related	Unplug heat-producing and rotating appliances if you can do so from a dry, safe position, then contact the local utility or accommodation
Is your luggage wet or damaged?	Evidence can disappear during cleanup	Photograph it first, separate items safely, and request a written report

If somebody is trapped, unconscious, badly injured, or in immediate danger, call 119 in Japan. Give the building name, address, nearest station, or another clear landmark. For a non-urgent travel problem, ask hotel staff, a station information desk, or the local authority instead of entering a closed area.

Why should I never enter floodwater?#

Floodwater is not just rain on a road. It can cover a drain or open manhole, move debris, mix with sewage, and hide a drop at the edge of a pavement. Water in an underground passage or basement can rise faster than you can climb out. Even water that reaches only the lower part of a wheel or suitcase can make movement difficult and may carry a person off balance.

Do not use a suitcase as a flotation aid, and do not send one person ahead to “test” the depth. Turn back before the water reaches the route. Avoid riversides, coastal edges, steep slopes, underpasses, and underground shopping or station areas until officials say they are open. A route can look passable at one end while water is entering from a side street or a river upstream.

If water is already around you, move toward a sturdy building or higher ground without crossing deeper or faster water. Tell accommodation staff exactly where you are. If you cannot move safely, call 119 and describe the water level, nearby building, floor, and visible landmarks. Do not return for a passport, camera, or suitcase if doing so takes you toward water.

How do I handle electricity after flooding or a blackout?#

Treat water and electricity as a combined hazard. A wet floor, outlet, extension lead, charger, appliance, or breaker panel is a reason to stop. Do not touch a plug while standing in water. Do not switch on a wet room’s lights, retrieve a phone charger from a puddle, or plug in a device just because its outside has dried. Water can remain inside and insulation can be damaged.

Look for these failure patterns:

What you notice	Do not do	Safer response
Fallen or sagging electric line	Do not approach, step over, or touch nearby metal	Move away, keep others back, and report it to the utility; call 119 for immediate danger
Sparks, smoke, heat, or burning smell	Do not pour water on electrical equipment	Leave the area and call 119 from a safe place
Water reached outlets, a power strip, or a breaker	Do not reset the breaker or test appliances	Keep the area unused; ask the property manager or a qualified electrician
Power suddenly returns	Do not leave irons, heaters, kettles, or hair dryers connected	From a dry, safe position, unplug heat-producing devices; follow utility or hotel instructions
Power is out but the room is dry	Do not use candles near luggage, curtains, or clothing	Use a torch or phone light, keep exits clear, and report the outage

TEPCO’s English outage guidance warns that a typhoon can cause outages and advises unplugging heat-producing and rotating appliances to reduce fire or injury risk when power returns. That is utility guidance for a safe, dry situation; it does not mean a visitor should enter a wet room or handle submerged equipment. If you are unsure, leave the electrical work to staff or a qualified professional.

Do not use a portable generator, camping stove, or charcoal burner inside a room, corridor, bathroom, or enclosed balcony. Carbon monoxide can build up without an obvious smell. Ask the accommodation where emergency lighting, drinking water, and a safe waiting area are located.

What should I do with damaged luggage?#

Protect people first, then preserve evidence. If the suitcase is in a flooded room, basement, vehicle, or station storage area, do not retrieve it until staff say the route is safe. If it is safe to move, place it on a dry surface without opening a swollen battery pack or handling a wet electrical item.

Take photographs or video before cleaning: the outside of the bag, damage to wheels or zips, mud or waterline, luggage tag, room or storage location, and each affected item. Add a simple note with the date, time, place, and what happened. Keep boarding passes, baggage receipts, hotel messages, purchase receipts, and transport disruption notices. Ask for the staff member’s name and a written incident number or report if the hotel, airline, rail operator, or storage facility has a reporting process.

For wet clothing, follow the accommodation’s advice about washing and drying. For passports, medicine, cash, cameras, chargers, or battery-powered items, do not discard or power them on immediately. Keep passports and travel documents separate and contact the relevant authority, carrier, insurer, or embassy if they are unreadable. A photograph is useful, but it is not a promise that a claim will be accepted; deadlines and exclusions depend on the responsible company or policy.

What should I check before travelling again?#

Use the actual departure point, route, and arrival area. Confirm that roads, rail services, airports, bridges, and the accommodation are operating. Ask whether lifts, card payments, water, air-conditioning, luggage storage, and charging facilities are working; a building may reopen before every service is restored.

As of July 2026, MLIT’s English disaster-prevention portal links to information about conceivable damage and flood-risk maps, while JMA provides warnings, advisories, and typhoon forecasts. Local notices may be more specific than a national page. If an official notice closes a road, trail, station area, river path, or building, do not bypass it for a shorter route. Keep your phone charged, carry identification and essential medicine, and save the accommodation’s address in Japanese so emergency services can locate you.

The practical rule is simple: a storm’s centre moving away is not clearance to explore. Wait for local instructions, stay out of floodwater, keep away from electrical damage, and record luggage loss only from a safe, dry place.
