Late summer and early autumn is typhoon season in Japan. If you're here between August and October, it's quite likely that you'll experience at least one "tropical cyclone". Smaller typhoons may pass over central Tokyo without doing serious damage. Those in mountainous and coastal areas usually face much bigger threats. However, every typhoon should be taken very seriously -- particularly those classed as super typhoons. Nervous in the metropolis and unsure of what you should be doing when a typhoon hits? Below, you'll find some tips. First: What exactly is a typhoon? Put simply, a typhoon is a tropical storm. A powerful, long-lasting tropical storm with very, very strong winds, to be clear. If it occurs over the Northwest Pacific Ocean (including Japan), a tropical storm is called a typhoon. If it occurs over the South Pacific or Indian Ocean, it's called a cyclone. And if it occurs over the North Atlantic, Central North or Northeast Pacific Ocean, it's called a hurricane. Whatever name you know them by, tropical storms are associated with dangerous winds, huge waves, extremely heavy rains, and flooding. Note: Typhoons can actually occur at any time of year -- their "season" is simply when they are most likely to develop. In the event of a typhoon, keep an eye on the media for updates Where to find general updates When typhoons approach, Japanese TV and radio stations broadcast advance warnings with the expected time and area of landfall. The most authoritative source of information about tropical cyclones in Japan is the Japan Meteorological Agency, whose website we recommend bookmarking. A good place to gauge the severity of the situation is the Japan Safe Travel Information website. It provides general info on what to do, plus a list of links and hotline numbers that provide help and information in case of emergency. Their X feed is always up to date with the latest storm status. The Japan Times has a special disaster news page, which can also be handy to bookmark. It becomes a live blog in the event of typhoons or other disasters in Japan. Look out for emergency announcements across media channels -- you’ll find out if you need to take any special precautions or actions. If you don’t speak Japanese, you can tune into NHK World News, which provides official information in English. You might also find emergency announcements (or, in extreme cases, evacuation instructions) on the website of the ward you are staying in. The most central wards are: Shinjuku Shibuya Minato Chuo Chiyoda Nakano Meguro However, most of those websites look like they are time-warped straight from the early 90s, and the English icon only takes you to a translation software version. The best site to check is probably Shinjuku Ward's, as it provides instructions on what to do in case of a natural disaster, in multiple languages. Schools and universities While shops often stay open in the case of smaller typhoons (but not super typhoons), many schools and universities close until the worst has passed, regardless of the size of the typhoon. Their shutdown announcements tend to be made at the last minute -- and are often in Japanese. If you are a teacher or student, the first thing you need to do in a typhoon is stay glued to social media. Look at the institution’s X account or Facebook page for updates. Where to find transportation updates If you are worried that your flight might be canceled, check the Haneda and Narita Airport websites for official updates. The JR East site will tell you if your Shinkansen (bullet train) is running on schedule. For local trains that are part of the JR network, like the Yamanote Line, you can also check the above-linked JR East site. For the subway, most lines are under the Tokyo Metro network, but some are privately owned. These include: Keiō Keikyu (connects to Haneda Airport) Keisei (connects to Narita Airport) Odakyu Tokyu Tobu Seibu Their websites should provide key information in English. Events Most events will be canceled in a typhoon -- check the official websites for updates. Take care of windows, bicycles, and potted plants You should close all doors and windows tightly before a typhoon (to avoid them blowing out or being otherwise damaged). If you have shutters, close them. If you live in Tokyo or are staying in an Airbnb/vacation rental, you might also want to bring any potted plants inside so they don't blow over. It's also a good idea to take down the washing pole and store it safely, if you have one that balances on hooks on your balcony, or is otherwise moveable. Bicycles should be secured or brought inside. Motorbikes also need to be secured, as they may blow over. Got a car? Don't park it under a tree. And if you have pets, it goes without saying that they need to be safely indoors with you. Stay indoors during the storm Typhoons are taken very seriously in Japan, as they should be. As with any extreme weather, during a storm or typhoon -- of any size or classification -- you should always stay safely indoors until it has passed. People do get hurt and sometimes even killed, though for smaller storms the risk of this is not always very high in Tokyo central. Before you go out, be sure to check the weather advice and whether anyone else is outside. Use common sense at all times, and if in doubt stay indoors. Regardless of where you are, avoid building sites, as scaffolding can be caught by high winds and cause serious and even fatal injuries. Also avoid rivers and other areas where there is a risk of flooding. Important: Don't forget to let your friends and family know where you are -- just in case. And remember -- the Japan Meteorological Agency website is useful for keeping track of typhoons and other weather events, and helping you plan your movements. They have an English tab you can toggle to, though the Japanese pages tend to be most up to date. Don't do anything that relies on public transport Trains, including the Shinkansen, trams, ferries, and buses may stop running -- or run on reduced frequency schedules during typhoons, meaning that you may get stranded if you try to get somewhere on them. Taxis may keep running, but the demand is very high -- don't bank on being able to get one. Bicycles are best left at home -- so if you really need to get somewhere, your best bet is to walk or use a private car if you have access to one. But, we repeat, please do not try and go anywhere until the typhoon has passed. Are flights canceled during a typhoon? Airplanes are often grounded during typhoons in Japan -- sometimes even over a full day or two, meaning that domestic and international flights can be thrown off schedule. What should I do after a typhoon in Japan? After a typhoon, it's best to shelter in place until the authorities have confirmed that it's safe to go outside. Check the news and social media for updates. When you do go out: Avoid beaches, rivers, and lakes Watch out for fallen trees, poles, and power lines If the exterior of your accommodation is damaged, take photographs and report it to the owner Keep yourself safe in the city during and after the typhoon. And if you're somewhere mountainous or coastal, use extreme caution! How can I prepare for a typhoon in Japan, in advance? It pays to be prepared for natural disasters, and typhoons are no exception. You can prepare for a typhoon in Japan by: Reading up on what to expect, should a typhoon make landfall in Tokyo or elsewhere Having an emergency kit ready at home and, ideally, at work too (you can make one yourself or buy one online, e.g. on Amazon) Familiarizing yourself with the location of evacuation shelters in your area Making a plan of action with your partner, family or housemates Remember: The Japan Meteorological Agency website publishes forecasts and warnings. It's a good idea to bookmark it if you are worried about a typhoon in Japan. This article is in no way intended to replace authoritative weather advice and should not be taken as such.
