Be prepared for Tropical Cyclones (Typhoons)


Tropical cyclones, or typhoons (台風 / taifū), like their Atlantic Ocean hurricane cousins, are massive clusters of cumulonimbus clouds with cyclonic rotation that cause strong winds and large amounts of rain, and can carry enormous destructive potential. Keep an ear open for talk of taifū, check weather forecasts to find out if one is on its way, and prepare accordingly.

  • Prepare a flashlight, radio, and batteries in case of electrical blackout
  • Pay attention to weather information on radio or television, and the Japan Meteorological Agency website (see below)
  • Reinforce windows and be sure to close any shutters if you have them
  • Bring objects at risk of being blown away (such as potted plants or laundry poles) indoors, or fasten them securely
  • Do not go outdoors unnecessarily
  • In areas at risk of flooding, move household goods to a higher location
  • Prepare food, drinking water, and medical supplies
  • Prepare valuables for quick evacuation
  • In at-risk areas, be prepared for quick evacuation at all times
  • Confirm the locations of evacuation areas beforehand at your local ward office, or on the City of Nagoya website here.


Evacuation Information 避難情報について

Evacuation information may be issued for areas at risk of flooding. Residents will be notified of evacuation information by TV and radio, mobile phone messaging services, the official City of Nagoya website, emergency loudspeakers and sirens*, loudspeaker vehicles and the local disaster relief headquarters.

As evacuation information is issued in Japanese, it is important to familiarize yourself with the Japanese terms for the three different kinds of evacuation information that can be issued.

Areas at risk of flooding due to heavy rain, etc. are indicated in the Flood Hazard Maps (あなたの街の洪水・内水ハザードマップ) issued by the City of Nagoya. Use the maps to familiarize yourself with the flood risk for the area around your home, and think about where to evacuate if the need arises.

*Sirens will sound only in the case of an Evacuation Advisory or Evacuation Order (Urgent). (Siren will sound for 3 seconds, followed by a 2-second pause, and repeat.)


◆Notice to Prepare for Evacuation / Commence Evacuation for Elderly and Disabled People
避難準備・高齢者等避難開始 (Hinan Junbi / Kōreisha-tō Hinan Kaishi)

This notice is issued to enable residents to prepare in advance to evacuate.
Elderly and disabled people should use this as a guideline to commence voluntary evacuation.

● Keep updated with weather forecasts and disaster information by TV, radio, etc.

● Confirm where you will evacuate, and how to keep in contact with family members.

● Prepare your emergency evacuation kit to take with you if the need arises.


◆Evacuation Advisory 避難勧告 (Hinan Kankoku)

This notice is issued to advise residents to evacuate due to the possibility of the area being affected by the disaster.

● Check on your neighbors, and help each other to evacuate.

● When evacuating, extinguish any naked flame (e.g. gas cookers), lock doors and windows, and take your emergency evacuation kit with you.

● It can be dangerous to evacuate once flooding begins. Think about evacuating upwards, e.g. to a higher floor in your home or a tall building nearby.

● Avoid evacuation areas that could become dangerous during a flood. Evacuation shelters will be established at municipal elementary and junior high schools in locations where safety is assured by evacuating to the upper floors.


◆Evacuation Order (Urgent) 避難指示(緊急)(Hinan Shiji [Kinkyū])

This notice is issued to order residents to evacuate as the risk of harm is imminent and the risk to residents’ lives has increased.

● Evacuate to a safe place.

● If you are unable to evacuate, seek temporary shelter in a reinforced concrete structure of 4 stories or more.

Flood Hazard Maps 洪水ハザードマップ
Do you live in a flood risk zone? 12 of Nagoya’s 16 wards have one of Nagoya’s three major rivers, the Shinkawa, Shonai, or Tempaku passing through them and have issued flood hazard maps highlighting the potential flooding risk each neighbourhood is in. The four other wards – Naka, Showa, Chikusa, and Meito, are regarded as low risk areas. Maps for each ward are visible in PDF format from the City of Nagoya website.
