How long is the flight to Japan from each US airport?

The FAA’s busiest US airports by passengers in 2024, the quickest first. Times are the estimated gate-to-gate time of a non-stop; the clock change is Japan’s time minus the airport’s, in January and in July.

18 of these routes are longer than any US route the estimate was measured on (4,983 miles), so treat those as a rough guide: the longer the flight, the more the wind moves it. LaGuardia, the 19th busiest, is left out: its flights are short-haul, and New York’s long flights leave from JFK and Newark.

Why the flight home is shorter

From Los Angeles the flight to Tokyo Haneda is about 11 h 51 min and the flight back 10 h 55 min. The difference is the jet stream, the band of west-to-east wind at cruising height: flying east you ride it, flying west you fly into it. The estimate carries that as a single measured effect of how far east a route goes, which is why the two directions of the same route differ.

What the clock says when you land

Japan is 14 hours ahead of New York in January and 13 hours ahead of New York in July, when US clocks are on summer time; 17 hours ahead of Los Angeles in January and 16 hours ahead of Los Angeles in July. Leave Los Angeles at noon on Wednesday, July 15, and a non-stop would land in Tokyo Haneda at about 3:51 p.m. the next day, Thursday, local time.

Flying into another airport

This page measures to Tokyo Haneda (HND). To Tokyo Narita (NRT) it is about 14 h 8 min from New York and 11 h 47 min from Los Angeles; to Osaka Kansai (KIX) it is about 14 h 29 min from New York and 12 h 21 min from Los Angeles.

Is there a non-stop?

Not from every airport in the table: the times are what a non-stop would take, and a connection adds its layover. Your airline’s schedule says which airports fly to Japan non-stop. For any pair of airports, the calculator above gives the distance and the time.

What is the time difference between Japan and the US?

How these times are made

Distances are great circles between the airports (OurAirports). Times come from one line fitted to the median scheduled gate-to-gate time of 5,797 US routes (US DOT, 2026-06): a fixed allowance, a time per mile, and a correction for how far east the route goes. Half of those routes are within 7 minutes of it. The busiest airports are the FAA’s 2024 passenger boardings. Your airline’s schedule is the real answer: winds, routings and the season move it by a few minutes on a short flight and by more on a long one.
