October 2019's Typhoon Hagibis goes to show typhoon alerts should be taken seriously—this one caused widespread damage and even affected Japan's Rugby World Cup scheduling. Every year, 20 to 30 typhoons of varying sizes affect Japan. Some of these may never reach the coast to make a lasting impact but several can cause flash rain, floods, and structural damage. Unfortunately, every year typhoon season catches many unprepared.
It’s important to know what to expect, take sensible precautions—and above all—remain calm. Most typhoons pass without major incident and monitoring news sources can keep you informed.
Instead of giving the typhoons specific names, they are referred to by number (i.e. the 16th typhoon of the year is "Typhoon Number 16") in Japanese media. Western Japan tends to suffer more damage from typhoons than the east coast. Typhoons almost always travel northeast, starting with Okinawa; thus, the Ryukyu Islands are heavily affected during the annual typhoon season. Although the number of typhoon-related casualties has decreased steadily in recent years thanks to sturdier buildings, however, it goes without saying that they can still cause damage and claim lives.
When do typhoons occur?
Typhoon season typically lasts from May to October, with August and September being peak months. It just also so happens to be one of the best times to visit Japan with so many festivals and events going on. If you're staying in Japan during the typhoon season, it's important that you know how to get accurate information and stay alert.
How typhoons affect travel
Don't take warnings and typhoon news lightly. It might be an annoyance when your vacation is interrupted by a typhoon but you'll be happier when you come out the other side, safe and dry. Aside from torrential rainfall and strong winds, the following can be typical before, during, and even after the typhoon makes landfall.
- Flights may be delayed, rerouted, or canceled.
- Train and bus services may be delayed or canceled.
- Businesses, including major theme parks, museums, shrines, and temples may shorten hours or close temporarily.
- Affected areas may endure power or water service interruptions.
- Roads may be blocked by debris and closed to traffic.
- Flooding may occur.
- There may be typhoon sirens that call for evacuation (covered later).
Preparing for a typhoon
Preparation is important during any natural disaster, and typhoons are just the same. Keep a level head and start preparing as soon as the typhoon is announced. Many stores and conbini will sell out of food (bread is usually the first the go) so you'll want to stock up fast. Make a checklist based on the items below and you'll be ready in no time.
- Check the weather before visiting Japan and during your stay.
- If a typhoon is moving toward you, make sure you know the proper evacuation area (hinanjo 避難所).
- Prepare an emergency kit. It may sound complicated but think small: non-perishable food, emergency numbers, a flashlight/torch and batteries, other mobile necessities.
- Charge all electronics in case of a power outage—this not only keeps you up-to-date but gives you something to pass the time with. (cell phones, iPads, mobile gaming devices, Kindles, etc.)
- Keep your passport, airline tickets, cash, credit cards, and other documents in a waterproof, sealed bag.
- Water! Have it in bottles (fill them up if you have spares). And residents can consider filling the bathtub.
- Residents: Bring in outdoor objects that could be blown away and secure larger objects—bicycles, laundry poles, etc.
- Residents: Close storm shutters if available.
During a typhoon
The typhoon has arrived. Stay calm. Don't panic. Here are some simple tips to keep you and your loved ones safe.
- Get the emergency kit you prepared somewhere accessible and ready to go.
- If you’re in the path of a typhoon, wear clothing to bed that you can go outside in.
- Avoid sleeping near windows.
- Do not go outside to take photos of the storm.
- Avoid coastal areas and river banks; these areas are likely to suffer flooding and may even experience a tsunami.
- If you’re in a place vulnerable to flooding, stay on the second floor.
- Stay up to date with typhoon advisories from the Japan Meteorological Agency.
- Stay away from downed power lines.
- With high winds, umbrellas are more of a hazard than a help.
- Stay indoors if you can; public transportation is likely to shut down or suffer terrible delays.
In case of evacuation
If you're staying at accommodation lodging, chances are that someone will brief you or staff will guide you in case of an evacuation. If, however, you're staying on your own or a friend's house, you may need to know the evacuation process.
“Evacuation” in Japanese is “hinan” (避難). Often loudspeakers in the area will announce whether or not it's necessary. The only problem is that these announcements are in Japanese and even then, they can be difficult to understand due to outside noise and the delay between words. Also note, pets are not allowed at most evacuation centers.
It can still be difficult to know if your area is evacuating, though a great tool (assuming you’ve charged your cellphone) is emergency apps, such as Safety Tips (Android/ iOS) which can be set to display hazard and evacuation information in English, Korean, and Chinese (simplified and traditional).
Other useful apps include:
- TyphoonInfo (iPhone) – Displays typhoon information issued by Japan Meteorological Agency
- Hurricane and Typhoon Track Pro (iPhone) – Shows the path of typhoons and expected affected areas, as well as a survival guide
- Typhoon Tracker (Android) – Provides information on location and intensity of typhoons in the Asian Pacific
- Twitter (Android / iPhone / Windows Phone)—Not just useful for letting your followers know you are okay, a number of organizations also support Twitter Alerts, allowing them to push crisis information to subscribers in real-time. Currently, these services are only available in Japanese.
