Seattle to Tokyo Haneda Flights (SEA to HND): Nonstops, Flight Time and Getting into Tokyo

Nonstop is normal, and Haneda is the airport you want

Seattle to Tokyo Haneda has nonstop service, and Seattle is one of the shorter US gateways for Japan. As of recent schedules, Delta and ANA (All Nippon Airways) both fly SEA to HND nonstop, with departures that generally leave Seattle in the early afternoon and arrive in Tokyo the following afternoon or evening, local time. Japan Airlines also serves Seattle, but its flight goes to Narita rather than Haneda, so check the airport code when comparing fares.

Haneda matters because it is the close airport. It sits on Tokyo Bay about 15 km from the city centre, while Narita is roughly 60 km out in Chiba. If your hotel is in central Tokyo, landing at Haneda saves an hour or more on the ground in each direction. Narita still makes sense for a connection onward within Asia, for a Chiba or Disney-area hotel, or when the fare gap is large.

One-stop options exist via San Francisco, Los Angeles, Vancouver or Honolulu, and United, American and Air Canada sell them. They sometimes come in cheaper, but a stop on a ten-hour route adds several hours and a second security line.

Flight time and distance, both directions

The great-circle distance between SEA and HND is roughly 4,790 miles (about 7,700 km), which makes this one of the shortest transpacific pairs from the mainland United States. Westbound, Seattle to Tokyo typically takes 10 to 11 hours in the air against the jet stream. The return from Tokyo to Seattle is faster at about 8.5 to 9.5 hours.

You cross the International Date Line heading west, so you land the day after you leave. Coming home, you can arrive in Seattle on the same calendar day you left Tokyo, sometimes with a clock time earlier than your departure. Double-check which night your first hotel reservation covers.

Leaving from Seattle-Tacoma

SEA has a single terminal with the A, B, C and D concourses attached and the North and South satellites reached by underground trains. International departures mostly leave from the South Satellite, where Delta and ANA usually park their Tokyo flights, though Delta also uses the main concourses, so check your gate on the day. The satellites have fewer food choices than the main terminal, so eat before you ride the train out.

Security at SEA has become slow at peak times as the airport has grown, and the early afternoon bank of Asia departures coincides with heavy domestic traffic. Arriving three hours before a Tokyo flight is sensible if you are checking bags, and the airport's reservation system for a security time slot is worth using if it is available for your flight. Link light rail runs from downtown and the University District to the airport station in about 40 minutes; the station is a short covered walk from the terminal.

Arriving at Haneda and getting into Tokyo

International flights at Haneda use Terminal 3, with a few ANA flights at Terminal 2. Immigration is efficient, and you will move faster if you complete the Visit Japan Web registration before you fly, which gives you QR codes for immigration and customs instead of paper forms. Terminal 3 has a tourist information desk, luggage delivery counters and SIM card vending machines in the arrivals hall.

The short ride into the city is the whole point of Haneda:

• Keikyu line: to Shinagawa in about 15 minutes, with connections to the JR Yamanote loop and the Shinkansen. Some trains continue through to the Asakusa line for the east side of the city.
• Tokyo Monorail: to Hamamatsucho in about 15 to 20 minutes, where you join the Yamanote line for Shinjuku, Shibuya and Tokyo Station.
• Limousine bus: direct to many major hotels and to Shinjuku, Tokyo Station and Disney, typically 30 to 60 minutes depending on traffic. Easiest with heavy bags.
• Taxi: 30 to 45 minutes to central districts; fixed fares to defined zones exist, and it is the practical choice after the last train.

Trains stop around midnight. If your flight lands late, the limousine bus and taxis are your options, and a hotel near the airport for the first night is a reasonable alternative.

When to fly and when to book

Japan's holiday calendar drives this route. Cherry blossom season in late March and early April, Golden Week in late April and early May, Obon in mid-August and the New Year period are the busiest and most expensive times, and seats from Seattle sell out months ahead. Late October and November bring clear autumn weather and softer demand. January and February are the quietest months, cold but dry in Tokyo, and the easiest for a good fare; they are also prime time for skiing in Hokkaido or Nagano, which Haneda's domestic terminals connect to easily.

June is the rainy season and late August to October is typhoon season, when a storm can delay flights for a day or two. For the peak periods, book three to five months ahead; otherwise six to ten weeks is usually enough.

Entry requirements and documents

As of recent rules, US passport holders can visit Japan for short tourist stays without a visa. Rules change and other nationalities differ, so check the Ministry of Foreign Affairs of Japan or your nearest consulate before you book. Your passport should be valid for the whole stay, and airlines may ask to see an onward or return ticket at check-in in Seattle.

Japan is strict about medicines. Some common US decongestants and ADHD prescriptions are restricted or banned, and bringing them in without the right paperwork is a serious matter. Check the Japanese rules for anything you take and carry a doctor's letter where required.

Time zones and jet lag

Tokyo is 16 hours ahead of Seattle during Pacific Daylight Time and 17 hours ahead in winter, because Japan does not use daylight saving. In practice you shift your body clock back about eight hours and lose a day on the calendar. Westbound is the easier direction: you land in the Japanese afternoon or evening and can go to bed at a normal local hour. The return is harder, with a morning arrival in Seattle after a short night; most people feel it for three or four days. Daylight, a light dinner and no long nap on day one help most.

What travellers on this route get wrong

The most common mistake is comparing a Haneda fare with a Narita fare without counting the extra hour and the cost of getting in from Narita. The second is skipping Visit Japan Web and queueing to fill in paper forms. The third is landing late and expecting a train; after midnight it is bus or taxi. None of these ruins a trip, but each costs time you would rather spend in Tokyo.
