Tokyo helicopter tour around the Asian Games in Nagoya: full refund or free date change on weather cancellations, the 4-day change rule and typhoon season tips.
The Asian Games Aichi-Nagoya 2026 run from 19 September to 4 October, and the Para Games from 18 to 24 October. Both fall inside a season when Japan is warm and humid, with temperatures of 20 to 30 °C, and when typhoon season is not yet over. If you are planning a helicopter flight in Tokyo, Yokohama or the Mt Fuji region as part of the trip, weather is the one variable you cannot book away.
The rules that protect you are simple. If your flight is cancelled because of weather, you receive a full refund or a free change of date. Separately, you can change your date free of charge yourself up to 4 days before the flight. Payment is made online when you book.
This article walks through what those rules mean on a real Games itinerary, when to book, how to build in a buffer and what to do on the day if the sky looks doubtful.
Two different rules, two different triggers
People often blur these together, so here they are side by side.
| Rule | Who triggers it | Cost to you | Deadline |
|---|---|---|---|
| Weather cancellation | The operator, on safety grounds | None: full refund or free new date | Applies whenever the flight cannot go |
| Voluntary date change | You | None | Up to 4 days before the flight |
The weather rule has no deadline because it is not your decision. The voluntary rule is your safety valve when your own plans move, for example if your group decides to stay in Nagoya an extra day for a final. After the 4-day point a voluntary change is no longer free, so lock your Games schedule before the deadline.
Why autumn matters here
Late September and early October weather in central Japan is usually pleasant, but the season carries two risks for flying. Typhoons can bring a day or two of strong wind and heavy rain with only a few days' warning. And even on days without a storm, low cloud can keep Mt Fuji hidden, which matters if you booked a Fuji flight for the view.
Operators make the go or no-go decision on safety criteria, not on whether the view is pretty. A grey day with acceptable wind may still fly. A bright day with strong gusts may not. Plan for both possibilities.
Where to place the flight in your itinerary
The most common mistake is to book the flight for the last morning before an international departure. If a typhoon sits over the Kanto region that day, you get your money back, but you do not get your flight.
Better options, using the Games calendar:
- Before the Games: arrive in Tokyo two or three days before the opening ceremony on 19 September, fly on the first or second day, and keep the third as a fallback before the Shinkansen to Nagoya, which takes about 1h40.
- After the Games: leave Nagoya on 5 October after the closing ceremony, fly on 6 October, and hold 7 October as the fallback day.
- Between the Games and Para Games: the gap from 5 to 17 October is long enough for a Tokyo stay with several possible flight days.
The principle is one flight day plus at least one spare day, with the spare day before any fixed departure.
Using the free date change as a planning tool
Because you can move the date free of charge up to 4 days out, you can book early to secure a slot on the calendar and then refine. Imagine you book a Tokyo night flight for 6 October while your Games tickets are still being confirmed. If your group later decides to attend a session in Nagoya on 6 October, you move the flight to 7 October at no cost, as long as you do it by 2 October.
Count the days carefully. "Up to 4 days before" means the change must be made before that point, so work from the flight date backwards and act a day early to be safe.
What happens on the day
If the weather is marginal, expect the decision to come from the operator close to the meeting time rather than the day before, because conditions change quickly. Keep your phone on and reachable from the moment you arrive in Tokyo. If the flight is cancelled:
- You choose between a full refund and a free new date.
- If you take a new date, you need to be in Tokyo, Yokohama or the Fuji region on that date, which is why the spare day matters.
- If you take a refund, the money returns by the method you used to pay online.
If the flight goes ahead, the time on your confirmation is the meeting time and the flight itself begins roughly 30 minutes later. Do not treat the meeting time as optional because you are watching the sky; be there.
Planning a weather-proof Tokyo day
Have a ground plan that does not depend on flying. A chauffeured car for the day can switch from a heliport run to a city drive without renegotiation, and it means a family with luggage is not stranded in Shin-Kiba when the cancellation call comes. Museums, indoor viewing decks and a good lunch all work in rain. If the flight then goes ahead, you simply do less of the ground plan.
Tell everyone in your group in advance that the flight is weather-dependent. Expectations set at booking make a cancellation a minor disappointment rather than the story of the holiday.
Checklist: booking a flight in typhoon season
- Book once your Games session dates are fixed, or be ready to use the free change before the 4-day cut-off.
- Put the flight at least one full day before any flight home or fixed Shinkansen.
- Keep a spare day within reach of the departure city.
- Save the OlaChill contact details from your confirmation.
- Prepare an indoor alternative for the same time slot.
- Remember that the refund covers the flight only, not hotel nights or train tickets booked around it.

FAQ
If it rains but the flight still operates, can I cancel for free?
The free weather remedy applies when the operator cancels for safety. If the flight goes ahead, the weather rule does not apply. Your own free change window closes 4 days before the flight, so if you want to avoid a grey day, decide before then.
Can I change the date twice?
Each change must be made before the 4-day point for the flight date you currently hold. If the new date is still more than 4 days away, you can move it again. Confirm with OlaChill if you are unsure where you stand.
Does the refund include my Shinkansen tickets from Nagoya?
No. The refund or date change covers the helicopter flight only. Trains, hotels and other bookings are separate, which is why the spare-day approach is safer than relying on refunds.
How will I know if my flight is cancelled?
The operator decides on safety grounds, often close to the meeting time when conditions are changeable. Keep the contact details from your booking confirmation and stay reachable on the day.
Is October safer than September for flying?
Typhoon season is not over in either month, and no date can be guaranteed. Whichever month you choose, the spare-day rule and the refund policy are what protect you.
