Typhoons & Rain in Japan: How to Keep Your Trip on Track

A typhoon is the Pacific's name for a hurricane. They form far to the south and tend to curve north toward Japan through the summer and early fall. The agency counts one as approaching when its center comes within 300 kilometers of a weather station in Japan, which is close enough to bring wind, heavy rain and disrupted transport even when it never crosses the coast.

None of this is a reason to avoid late summer. It is a reason to plan for it. A trip in August or September should have at least one day that can move, and the long-distance travel days, the ones that are hardest to shift, should not all sit back to back at the end.

The first instinct when a storm appears on the map is to cancel the days underneath it. Resist it. When our guest sent that message, our planner's first reply was simple: typhoons are not always accurately predicted, so he would not consider those days lost yet. That turned out to be right. Over the next two days the predicted track shifted south, and the days that needed to change were not quite the ones it had first looked like. The decisions were made once the track firmed up, not before.

The Japan Meteorological Agency is the source the rest of Japan works from: trains, airlines, schools and city offices all take their decisions from its warnings. Its typhoon map shows the forecast track and the widening cone of uncertainty around it. The width of that cone is the honest answer to “will it hit us?” Five days out it is wide. Two days out it narrows enough to act on.

Japan's railways do not gamble with weather. When a strong typhoon approaches, operators often announce reduced or suspended service in advance, sometimes the evening before. That is good news for safety and frustrating for anyone with a ryokan booked three hundred kilometers away. The worst place to be on a typhoon day is a crowded station, waiting for a train that will not run.

The money, at least, is straightforward. On JR Central's published rules, a cancelled ride means the full fare and charges are refunded; if a suspension forces you to abandon a trip partway, you can return to the station you started from at no charge. Discounted tickets and rail passes follow their own rules, so ask the staff at the ticket office, and keep your ticket.

The practical lesson is about timing, not refunds. If a storm is forecast for the day you planned to move cities, move the day before, or move the day after. Do not plan to travel straight through it.

Most travelers think about a typhoon as a problem for the day it arrives. The better way to think about it is as a reshuffle of the three or four days around it. The days before a typhoon are often clear, hot and perfectly usable. That is when the outdoor plans, the deer park, the hike, the garden, should happen.

1. Pull outdoor days forward. If the park or the mountain is scheduled for the storm day, look for a way to do it a day or two earlier, even if it means swapping with something else.
2. Stay put on the storm day. Cancel the long transfer, keep the hotel, and if needed extend a night rather than moving through the weather.
3. Make it an indoor day, close to home. Museums, a digital art space, a cooking class, a long lunch, a spa, or a salon that comes to you. Short distances matter more than the activity.
4. Book on weather-proof terms. Before you pay for any guide, car or experience, ask what happens if weather cancels it.

That last point matters more than it sounds. On a different family's trip, in the rainy season, we proposed booking a riverside lunch so the children could do the flowing-noodle experience in the hills above Kyoto. The father's only question was the right one:

Once we confirmed that a weather cancellation would cost them nothing, the answer came back in seconds: “Let's do it.” Flexibility is what makes people willing to book the good things at all.

Moving a day, cancelling a guide, finding a car when every local company is booked out, getting the refunds back: it is a lot of phone calls to make in a language you do not speak, in the middle of your holiday. That part we take on. Start a conversation →

The rainy season and typhoon season are easy to confuse, and they are very different things. A typhoon is a single storm that can shut down transport for a day. The rainy season is a stretch of several weeks when a seasonal front sits over Japan, bringing overcast skies, showers and humid heat, often with dry spells in between. It is also when hydrangeas line the temple paths and the moss gardens are at their most vivid.

Before one family's June trip, our planner wrote to them about the weather. Hotels keep loaner umbrellas, a light raincoat that breathes in the heat and proper shoes are worth packing, and private transport between stops takes most of the sting out of a wet day. He ended the note with a line we still use:

It did rain, one afternoon, in Nara. It became one of the best photographs of their ten days. You can read the whole trip in our story of that family's ten days in Japan.

Here is how the five days after that first message actually went, from our side of the conversation.

We asked how the last day went. The reply:

And when we said we hoped the typhoon had not spoiled the end of the trip:

Nothing about that week was dramatic. That is the point. The storm still came, and two plans were still lost. But the family spent their last days doing things they enjoyed instead of standing in a station. Read the full week in Seven Days in Japan with a Las Vegas Family.
