Japan’s railway is famous for not stopping. What is less well covered is what happens on the days it does — and the operator has published the whole procedure in English, in a Q&A almost nobody quotes.
This matters most between August and October, when typhoons arrive, but the rules underneath apply to wind, rain, snow, earthquakes and volcanic ash all year.
The sentence that changes how you read an announcement
Start here, because it is the single most useful thing on the page and it is buried in a diagram.
When services are suspended and then restored, JR East does not announce the moment the first train moves. In its own words, stations may be very crowded right after services resume, since trains will be lower in number and operating less frequently than usual — and this is why JR East notifies passengers of the time in which reliable services resume as the time of the resuming of services.
Read that twice. The announced time is a promise about reliability, not a starting gun. Two things follow:
- Turning up at the announced time puts you in the worst crowd of the day. Everyone who has been waiting has the same number.
- Service before that time may exist but is not being promised to you. Trains are released from storage gradually, and empty trains are run first as a final safety check.
If you have any flexibility at all, the hour after the announced resumption is the hour to avoid.
A typhoon cancels trains before it arrives
This is the part that surprises visitors most, because it looks like an overreaction from a window where it is not yet raining hard.
JR East states that where there is a risk of serious damage to railway facilities over a wide area, it may preemptively cancel train services, based on its assessment of information from the Japan Meteorological Agency and private weather information services. The announcement goes out on the website, in stations and on social media.
The sequence it publishes runs: notice of suspension → trains moved into storage facilities → all lines suspended → after the wind and rain stop, lines inspected for blown objects and fallen trees and facilities checked for damage → trains released steadily with empty runs as a final check → numbers increased gradually back to normal.
The consequence for a traveller is simple and unintuitive: the decision that strands you is made the day before, in good weather. If a major typhoon is forecast, the question is not whether it will be raining hard enough on the day. The question is what the operator has already announced.
Suspensions outlast the weather that caused them
Two separate reasons, both from the operator, and both explain the situation where the sky has cleared and nothing is running.
Wind. If services are disrupted by objects blown onto the line, JR East says services may continue to be suspended even after the wind subsides. The wind is gone; whatever it put on the overhead lines is not.
Rain. JR East answers this one directly — why doesn’t service resume as soon as the rain stops? Because rainfall absorbed into the earth still may affect railway facilities, and services resume only after staff have inspected the condition of facilities on the entire line once rainfall drops below the restriction threshold.
So a clear sky is not information about the trains. The status page is.
The three-step escalation, which is the same for wind and rain
Neither is binary. Both run through a middle state that is easy to miss and matters for planning:
| Condition | What happens |
|---|---|
| Normal | Trains run as usual |
| Middle | Speed restrictions. Trains run slower. For rain, facility staff board trains to inspect periodically, or inspect predetermined high-risk sections |
| Severe | Service suspended |
That middle state is where most trips actually go wrong, because nothing is cancelled and everything is late. A connection with twenty minutes of slack does not survive a line under speed restrictions. If you are moving between cities on a bad-weather day, the schedule is the thing to loosen, not the plan.
Snow works the same way with four steps in the Greater Tokyo area — normal, normal with caution, limited service, suspended — and JR East says reduced-train service is announced to passengers in advance.
Earthquakes, and what a station becomes
A large earthquake suspends service immediately, and the restart is slower than for weather because the whole affected area has to be inspected for damage on foot or using track inspection vehicles. JR East states that the top priority is evacuating passengers stuck on trains stopped between stations — ahead of restarting anything.
What is worth knowing before you need it is what happens to the building you are standing in.
- The station opens as a temporary stay location until people can move to the temporary stay facilities designated by the authorities.
- Emergency supplies are prepositioned: drinking water and food, portable toilets, aluminium blankets.
- Restrooms and public telephones are opened, and staff provide earthquake and operation information at the station.
- JR East asks people to return home in a dispersed manner rather than all at once, and notes that admission to stations may be restricted.
It also gives the advice that matters in the first minutes: the shaking has stopped but aftershocks are a risk, so stay in a safe place rather than immediately setting off.
There is a published list of station temporary stay locations, linked in the sources below. It is not a page to look for during an earthquake; it is a page to have seen before one.
Volcanic ash is its own category
Falling ash worsens visibility for crew, can make switches inoperable, damages electrical equipment and covers the rails. Services are suspended until the ash is removed — which is a clearing operation, not a waiting one, and therefore not a function of when the eruption stops.
Refunds, in the shape the operator uses
When JR East suspended a section of the Tsubasa and Komachi Shinkansen this year, the instructions it published are a good guide to how this works generally:
- Paper tickets covering the suspended section are refunded at a Midori no Madoguchi ticket office, within one year from the day after the intended travel date.
- The operator specifically recommends not going on the day, because the ticket office will be crowded. The one-year window exists so you do not have to.
- Shinkansen e-tickets were refunded by the Ekinet Support Center with no action needed from the passenger, though processing takes time.
Those terms were published for one specific suspension, so confirm yours against the notice for your own line. The useful general lesson is the second point: joining the refund queue on the day of a disruption costs you the day and gains you nothing.
What a rail refund does not cover is the rest of the day it took with it — the hotel you did not reach, the connection you missed, the flight the next morning. That is what travel insurance is for, and whether it is worth buying is a separate question we treat separately in our travel insurance guide. It is worth reading before a trip, not during a suspension.
The three tools, and which one is which
JR East publishes these separately and they do different jobs:
- Train Status Information — line-by-line status by area. This is the one to check before you leave.
- Real-Time Route Search — a route search that reflects current delays. This is the one that answers “so how do I actually get there now”, which a normal timetable app will not.
- Doko-Train — shows where trains actually are, covering lines outside the greater Tokyo area.
Service information also goes out on JR East’s official service accounts on X, which in practice update fastest.
How to decide
- Check the status page, not the sky. The two disagree routinely, and only one of them runs the trains.
- If a major typhoon is forecast, look for an announcement the day before. The cancellation decision is made in advance.
- Do not arrive at the announced resumption time. That is the promise of reliability and the peak of the crowd, simultaneously.
- Loosen connections on bad-weather days. Speed restrictions delay far more trips than suspensions cancel.
- Do not queue for a refund on the day. You have a year, and the operator says so itself.
- Look at the temporary stay location list once, now.

These procedures are JR East’s and apply to JR East lines; other operators publish their own, and the thresholds differ line by line because they depend on the facilities on each. Everything above was read from JR East’s own English publications on 2 August 2026. Check the status page for your line on the day.
