Bag allowance on domestic flights in Japan
Your suitcase was fine on the flight from Malaysia, but you worry about the next flight in Japan.
Trains, roads and flights
One ticket or two for domestic connections
You fly on from Tokyo within a day, and wonder what happens if the first plane is late.
If you can book a single ticket from Kuala Lumpur to your Japan domestic destination, do so. If you book two tickets, build a large buffer or sleep one night near the airport.
This guide explains the risks in plain words and gives a step list for connection day.
What does one ticket protect?
On one ticket, the airline treats the whole trip as one booking. If your first flight is late and you miss the second, the airline normally helps you rebook.
The rules depend on the airline and fare, so ask what your ticket covers. Some one-ticket trips also check bags through to the final airport.
What is the risk of two tickets?
On two separate tickets, each airline is responsible only for its own flight. If the first plane is late and you miss the second, you may need to buy a new fare yourself.
Delays, immigration queues and bag waits all eat into the gap. For a family with children or elders, the risk is greater, because everything moves more slowly.
What steps happen on connection day?
Expect these steps on two tickets:
- Clear immigration.
- Collect your bags.
- Clear customs.
- Move to the domestic terminal, which may be a different building.
- Check in again and drop your bags.
- Go through security.
Add buffer for each. Our guide on domestic baggage versus international allowance covers the weight limits that can change on the second flight.
How much buffer do you need?
Ask both airlines for their minimum connection times, then add more. On separate tickets, a same-day connection is a gamble, and a night near the airport is safer.
Landing times from KLIA, KLIA2 and Penang differ by airline and season, so use the time on your own ticket. Read the first night near New Chitose if you are flying on to Hokkaido.
Which Tokyo airport should you land at?
Tokyo has two international airports, Haneda and Narita, with different links to the city 1. Domestic flights leave from both in different amounts, so check where your onward flight departs.
Read Haneda or Narita for Malaysian flights before you book the international leg.
What about low-cost carriers?
Low-cost domestic carriers can have strict baggage rules and separate check-in counters. Read low-cost domestic baggage rules before you choose a carrier, and compare it with the Shinkansen in Tokyo to Sapporo: flight or train.
If you plan to fly on to Sapporo, Fukuoka or Okinawa soon after landing, send us your flights. We reply with whether to sleep near the airport, and how to set the buffer.

You are tired of the idea of driving the same long roads twice.

Questions travellers ask
What is the difference between one ticket and two tickets?
On one ticket, the airline treats the whole journey as one booking. If the first flight is late and you miss the second, the airline normally helps you rebook. On two separate tickets, each airline is responsible only for its own flight, so a missed connection can cost you a new fare.
Do I collect and re-check my bags?
It depends on the ticket and the airline. On one ticket, bags are sometimes checked through to the final airport. On two tickets, you usually collect your bags, clear immigration and customs, then check in again. Ask your airline before you book.
How much buffer should I build between flights?
More than you think. Add immigration, bags, a possible terminal change and check-in for the second flight. With separate tickets, a same-day connection is risky, so many travellers sleep one night near the airport. Ask both airlines for their minimum times.
Which airport should I land at?
Tokyo has two international airports, Haneda and Narita, and domestic flights leave from both in different amounts. Check where your domestic flight departs before you choose the international arrival airport, so you do not have to cross the city.
