The Seattle–Tokyo route
SEA–NRT is a long-haul pairing from the United States to Tokyo: roughly 4,757 miles. Nonstop SEA–NRT is often on the schedule, about 10 hours airborne over 4,757 miles. Overnight westbound is common; compare arrival local time, not only the duration field.
For SEA–NRT we show about $389 on the low end and around $670 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $389 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.
Search SEA to NRT on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time SEA–NRT
Great-circle distance SEA–NRT is about 4,757 miles. Block time on a nonstop is typically near 10 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
Tokyo is about 17 hours ahead of Seattle on standard time (America/Los_Angeles vs Asia/Tokyo). Arrival clocks on NRT are local. That matters more on this pair than on a same-zone hop.
When SEA–NRT has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Seattle to Tokyo
You depart Seattle-Tacoma International in Seattle, United States, and arrive at Narita International in Tokyo, Japan. SEA is the origin code we use on this guide; NRT is the arrival code. If you need a visa or an ESTA, that is between you and the destination government — Azurovia does not ticket and does not process immigration.
SEA is the only origin code we list in this metro. On arrival, HND (Tokyo) can price differently from NRT. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
