    Basic information on typhoons in Japan

    The annual number of tyhpoon cases in Japan is around 20. Out of these cases, about 2 or 3 will tranform into powerful typhoons which are called “Super Typhoons”. These are the ones you have to look out for.

    Typhoons spawned in the Pacific Ocean make their way to places such as Okinawa, Wakayama/Mie (Kii Peninsula), Chiba Prefecture, and other coastal areas on the Pacific Ocean side. These locations are at high risk and may sustain heavy damage.

    Hagibis caused extensive damage in 2019, with a central pressure of 915 hPa, maximum wind speeds of 55 m/s, and 942 mm of precipitation in a 24-hour period in the town of Hakone, famous for its hot springs. As a result, 94 people were reported dead or missing and 376 were injured.

    Typhoons in Okinawa

    Okinawa's typhoon season is between July to October. The peak month for typhoons is July, and during this period there are 1 to 2 typhoons expected to hit the island every month. During this season, Okinawa is crowded with tourists enjoying different marine activities, however, in the cae of the typhoon, these activities will be cancelled until further notice for safety reason. Hotels and restaurants are also affected by the typhoon and some may operate differently than usual. These typhoon are kind of an annual tradition and visitors should be alert for any incoming typhoons during these months.

    Collect information about the typhoon

    If you find out a typhoon is on its way, the first thing to do is collect as much information as you can. Japan's TV weather broadcasts are highly informative. The first channel you should check out is NHK (Nippon Hoso Kyokai) which is the national broadcasting channel.

    The information is provided in Japanese, but it will give you a good idea of how big the typhoon is. If the typhoon is dangerous, a QR code will be displayed at the bottom of the screen where foreigners can visit a website for helpful information. Go to NHK World or get the lastest information via the app.

    If you want to gather information a little more easily, go to the Meteorological Agency website.

    You can even collect information via Twitter.

    Airport during Typhoon

    Japan's major airports (Tokyo, Osaka, and Nagoya) are located on the Pacific side making them easy targets for typhoons. In the case of a super typhoon, all flights may be canceled.


    Check the official website of each airport
    Haneda Tokyo International Airport
    Narita Airport
    ※For more information, go to "Helpful Links" at the end of this article

    If you already have plans to go on a flight, just remember that the traffic to the airport could be hellish. Going to the airport early than usual or checking for a vacant hotel room in advance might be a good way to go about it.

    In the worst case scenario, planes may be grounded for up to two days. Consider bringing along some water, food, spare battery, etc.

    Free WiFi during disasters

    A public wireless LAN service (public Wi-Fi) is free to use for anybody in the affected areas. This is so that you can check safety notifications without relying on mobile phone networks in the event of a large-scale disaster such as an earthquake or flood. The SSID for the free WiFi is “00000JAPAN”.

    To connect to the WiFi, all you need to do is select the network “00000JAPAN” (SSID) at your WiFi settings screen.

    Avoid entering personal information (banking, shopping, etc) since this is a public network with little to none secutiry.
