What do people get wrong about typhoon season for travellers?

This answer is a draft. It stays unpublished until legal review and source verification are complete.

Typhoons reach Japan mostly from July to October, peaking in September, and each year some visitors are stranded by cancelled trains and flights. The storms themselves are well forecast; the misunderstanding is about how transport reacts.

The pattern

• Planned suspension (計画運休) became standard after the 2018 and 2019 typhoons: operators publish the stop time and expected restart so people stay home. Restart is often the following morning, after track inspections.
• Typhoon Hagibis (October 2019) cancelled more than 1,600 flights and stopped most rail in the Kanto region for a day; the Rugby World Cup lost matches.
• Travel insurance typically covers delays; airlines rebook without fees for weather cancellations, but seats on the next day are scarce.

[Verify] Landfall statistics with the JMA's typhoon database; planned-suspension practice with JR East/West announcements.

Misunderstanding 1｜A typhoon means a wet day; carry on

Transport stops before the storm and restarts after inspection; the wind itself makes walking dangerous (flying signage, umbrellas are useless). Plan to stay put, with food bought the day before (convenience stores empty out of bread and onigiri).

Misunderstanding 2｜Trains will run until the weather is actually bad

Planned suspensions start hours before landfall, sometimes from the previous evening. Check the operator's site the day before; move to your next city early or stay an extra night.

Misunderstanding 3｜Flights are the reliable option

Domestic flights are cancelled en masse and international ones delayed. Airlines rebook free, but the next day is oversubscribed. Give yourself a buffer day before an international departure in September.

Misunderstanding 4｜The hotel will be dangerous

Modern hotels are safe places to wait out a typhoon; stay away from windows on the windward side, and expect the restaurant to close. Ryokan in mountain or coastal areas may evacuate — follow staff.

Misunderstanding 5｜Once the rain stops it is over

Rivers peak hours after the rain; landslide and flood warnings continue. Trains restart after track inspection, often the next morning. Check JMA and the operator, not the sky.
