A nonstop flight from Seattle-Tacoma International Airport (SEA) to Tokyo takes about 10 hours and 20 minutes to 10 hours and 50 minutes. The flight covers roughly 4,750 to 4,800 miles (7,640 to 7,725 kilometers), with travel time varying slightly depending on whether you land at Haneda or Narita Airport.
If you choose a connecting flight to Tokyo Haneda (HND) or Narita (NRT), expect the journey to take around 13 to 18 hours, sometimes longer. The total time depends on your route, where you change planes, and how long your layover lasts.
Departure Airport
Seattle-Tacoma International Airport (SEA) is the main airport for nonstop flights to Tokyo.
Arrival Airports
Tokyo has two major international airports, Haneda Airport (HND) and Narita International Airport (NRT), both receiving nonstop flights from Seattle.
Nonstop Flight Availability
Travelers can fly from Seattle to Tokyo without changing planes, with services available to both Haneda and Narita.
Common Connecting Airports
Vancouver (YVR), San Francisco (SFO), and Los Angeles (LAX) are among the airports used for connecting journeys.
Arrival Time
Most nonstop flights leave Seattle during the day and reach Tokyo the following afternoon or evening because of the time difference and International Date Line.
Flight Schedule
Departure times, airlines, and arrival airports vary depending on the travel date and selected service.
Flight schedules may change, so check your arrival airport, local arrival time, and travel date before making further plans in Tokyo.
Tokyo is 16 hours ahead of Seattle during daylight saving time and 17 hours ahead during standard time. This happens because Seattle changes its clocks during the year, while Japan keeps the same time throughout the year.
Seattle follows Pacific Time (PT), while Tokyo uses Japan Standard Time (JST).
For example, when Tokyo is 16 hours ahead, a nonstop flight leaving Seattle at 12:00 PM and taking 10 hours and 40 minutes would arrive in Tokyo at approximately 2:40 PM the following day, local time.
Flights from Seattle to Tokyo also cross the International Date Line, which means travelers usually arrive on the next calendar day. Always check the arrival date on your ticket before booking hotels or arranging airport transportation.
Flight times between Seattle and Tokyo can vary, even if you're flying nonstop.
Winds over the North Pacific play a big part in this. Depending on their direction, they can help the plane move faster or slow it down. That's why your flight to Tokyo may take a different amount of time than your flight back to Seattle.
Weather, air traffic, and changes to the flight route can also affect how long you're traveling.
The flight time on your ticket includes the time the plane spends moving on the ground before takeoff and after landing. So, you may actually spend less time in the air than what's shown on your ticket.
If you have other travel plans after landing in Tokyo, check your arrival time and leave enough time to go through immigration, collect your bags, and get to your next destination.
