How Long Does It Take to Travel from Portugal to Japan?

The honest answer to "how long is the flight from Portugal to Japan?" is that it depends on what you count. The time in the air is only part of it. Add the connection, the airport time at both ends and the train into the city, and the journey is a long day that ends in a different calendar day. This guide explains the typical times, the routes you are likely to see, which airports to use, what the time difference does to your body clock, and the Japanese words you will meet along the way.

The short answer

• There is no scheduled non-stop flight between Portugal and Japan that we could find. You change planes at least once.
• A one-stop journey from Lisbon or Porto typically takes about 17 to 24 hours from first take-off to final landing, depending on the connection and the airline.
• Add roughly three and a half to six hours for the airport at both ends and the train to your hotel, so plan on a travel day and a half.
• Japan is 9 hours ahead of mainland Portugal in winter and 8 hours ahead in summer, so you lose 8 or 9 hours going out and get them back coming home.

Checked on 21 October 2026: we looked at the published destination lists for Lisbon and Porto airports and at flight-search results, and found no Japanese destination with scheduled non-stop service. Those lists can be incomplete and airlines change their networks, so run a search for your dates before you plan around this.

Flight time versus total journey time

Add those up and a typical itinerary is about 14 to 25 hours from first take-off to final landing, and the clock from leaving home to reaching your hotel is closer to a full day and a half. Treat the airline's flight time as the smallest number in the calculation.

Common routing patterns

A note on airspace. Since 2022 many European airlines have avoided Russian airspace on flights to East Asia, which has lengthened some routings to Tokyo compared with the older schedules. As far as we could tell on 21 October 2026, that is still the case for many European carriers, but airlines differ and we did not verify current schedules, so the ranges above are approximate and you should compare real flight times when you search.

Lisbon, Porto or Faro

• Lisbon has the most long-haul and hub connections in Portugal, so it usually gives the most options and the best chance of a short connection.
• Porto has fewer long-haul connections. Some itineraries from Porto work well through a hub in Europe, but it can be cheaper to position on a separate flight to Madrid or Lisbon, with the risk that a delay on the first ticket costs you the second.
• Faro has far fewer connections to the big hubs outside summer, and one-stop itineraries to Japan often go through Lisbon or a European hub first.
• Compare the total price and the total journey time, not only the headline fare. A cheap fare with a long layover can cost more in time than it saves in euros.

Which Japanese airport?

• Haneda (HND): the closest of Tokyo's airports to the centre, which usually means a shorter and cheaper trip into the city.
• Narita (NRT): further out, east of Tokyo, with more long-haul flights historically but a longer train ride to the centre.
• Kansai (KIX): the airport for Osaka, Kyoto and the Kansai region. If your trip starts there, you save a day of cross-country travel.

If you are landing at Kansai, see our guides to getting from the airport to Kyoto and from the airport to Osaka.

Connection times and tickets

• Airlines publish a minimum connection time for each hub. It is the shortest the airline considers workable, not the most comfortable.
• Two to three hours is a comfortable buffer at a big hub. Under 90 minutes is tight, especially if you change terminals or go through security again.
• A single ticket protects you. If the first flight is late and you miss the connection, the airline rebooks you at no extra cost.
• Two separate tickets (a self-transfer) mean that a delay on the first is your problem. You will usually have to collect your bags, check in again and buy a new ticket if you miss the second flight.
• Ask whether your checked bag is through-checked to Japan on a single ticket. If it is not, you must collect it at the hub and check it in again.

The time difference

Japan is on UTC+9 all year and does not change its clocks. Portugal does, which is why the gap shifts between 8 and 9 hours for the mainland. The Azores are one hour behind the mainland, so the gap is one hour bigger. Madeira follows mainland time.

What the time difference does to the journey

Travelling east, you lose hours. A flight that leaves Lisbon in the morning and takes about 22 hours door to hotel will land the following afternoon or evening in Japan, not the same night. An evening departure tends to land the next night or the morning after. Coming home, you gain the hours back, and a morning departure from Tokyo can land in Portugal in the evening of the same calendar day.

These tables assume a 13 hour flight from Istanbul to Tokyo and a 4.5 hour flight from Istanbul to Lisbon. Real timetables differ, so use them to see the pattern, not to plan. The point is that you can leave Tokyo late in the morning and still land in Lisbon on the same calendar day, a few hours before midnight.

Jet lag

Flying east is usually harder than flying west, because you have to fall asleep earlier than your body expects. These are general travel habits, not medical advice, so speak to a doctor if you have a health condition or take regular medication.

• In the days before you leave, shift your bedtime and wake-up earlier by an hour or so if you can.
• Set your watch and phone to Japan time as you board, and try to sleep and eat according to Japan time on the plane.
• On arrival, get outside in daylight. Light is the strongest signal for your body clock.
• Avoid a long nap on the first afternoon. If you need one, keep it to 20 to 30 minutes.
• Time caffeine for the morning and early afternoon, and avoid it in the evening.
• Drink water on the flight, go easy on alcohol, and plan a light first day.

What to pack for the long flight

• Passport, printed or offline copies of your bookings and any visa or entry documents you need.
• Phone, charger and a power bank in your cabin bag. Check the airline's rules for power banks.
• Headphones, a book or downloaded films and music.
• A change of clothes, a toothbrush and basic toiletries in your cabin bag in case your checked bag is delayed.
• A refillable water bottle to fill after security.
• A light layer or scarf, since cabins can be cold, and comfortable socks.
• Medicines you need, in their original packaging, plus a copy of any prescription.
• An eye mask and earplugs if you want to sleep.

Two more planning guides help here. If you do not want to drag a big bag across Tokyo's trains, read about luggage forwarding in Japan, and before you book, see whether you need travel insurance for Japan.

Official information

Checked on 21 October 2026: the Haneda Airport access page, which offers a route search from each terminal by train, monorail and bus, and the Narita Airport rail page, which lists the Narita Express, JR lines and the Keisei Skyliner and Access Express. Neither page quoted journey times in the text we could read, so check the operator or the route search for current times and fares. We could not fetch a Kansai Airport page, and the flight times and routes above come from our own planning knowledge rather than an official source.
