15-Second Answer
If a typhoon is approaching, assume transportation may stop and plan around that. Stay indoors during the storm, avoid unnecessary movement, and check official sources for updates. Preparing water, food, and a charged power bank before the typhoon arrives is the right move. Waiting it out safely is always better than trying to push through it.
When Do Typhoons Hit Japan?
Typhoon season in Japan runs roughly from July to October, with August and September seeing the most frequent landfalls and close approaches. The exact timing, track, and intensity vary significantly from year to year — where a typhoon hits depends entirely on its path, so the regions most commonly affected (Okinawa, Kyushu, Shikoku, the Tokai coast, and the Kanto area) are not always the ones impacted in any given storm.
Checking current forecasts from official sources as a typhoon develops gives a much more accurate picture than general seasonal expectations.
What Happens to Transportation?
As a typhoon approaches, train services — including shinkansen — may be suspended when wind speeds exceed safe operating thresholds. Airlines cancel or reschedule flights. Highways and ferry routes close. This is called keikaku unkyuu (planned suspension), and operators announce decisions in advance when possible.
Announcements typically come out sometime between the day before and the morning of the storm, but timing varies by operator and line. Do not wait for official confirmation before making alternative plans — check your route's operator directly and assume disruption is possible.
How to Stay Safe
- Stay indoors — once the storm is close, the safest place is inside your accommodation
- Do not use an umbrella in strong wind — it will not help and can become a hazard; if you must go outside briefly, move in short bursts between sheltered spots
- Stay away from rivers, coastlines, and low-lying areas — flooding and storm surge develop quickly and without much visible warning
- Follow the guidance of local staff — hotel and ryokan staff will know what is happening and will tell you if something requires action
Before the typhoon arrives, buy water, food for a day or two, and make sure your devices are charged. Convenience stores sell out of basics quickly once a typhoon warning is issued — earlier is better.
Where to Get Information
- Japan Meteorological Agency (JMA) — jma.go.jp — English-language typhoon tracking, warnings, and advisories
- NHK World — English-language news and typhoon updates from Japan's public broadcaster
- Your accommodation's front desk — the most reliable source for what is actually happening locally
- Transport operators' official websites and social media — for real-time service status on specific lines and routes
What Japanese People Actually Do
Stock up on food and water before the storm arrives, keep an eye on the forecast, and do not go outside unless necessary. The attitude is practical rather than anxious — typhoons are a known seasonal reality, and the approach is to prepare sensibly and wait it out. Trying to push through the storm to keep to a schedule is not something most people here would attempt.
Bottom Line
When a typhoon is coming, the right approach is to check the latest information, assume your transport may not run, stock up early, and stay put. Keeping to your original schedule is not worth the risk. Waiting it out safely is the correct call — and it is what everyone around you will be doing too.
