For IAD–NRT we show about $529 on the low end and around $925 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $529 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.

Distance and time IAD–NRT
Washington and Tokyo sit about 6,739 miles apart. If a nonstop is missing from IAD, timed itineraries near 13.5 hours of flying usually mean one long-haul plus a shorter feeder — not two equal hops.
Tokyo is about 14 hours ahead of Washington on standard time (America/New_York vs Asia/Tokyo). Arrival clocks on NRT are local. That matters more on this pair than on a same-zone hop.
Most Washington–Tokyo journeys connect rather than fly nonstop from IAD. Timed one-stop itineraries often bank at Los Angeles International (LAX), San Francisco International (SFO), Seattle-Tacoma International (SEA). That is a pattern, not a promise for your dates. On results, sort by fastest if you care about layover pain, or cheapest if you do not.
Airports for Washington to Tokyo
You depart Washington Dulles International in Washington, United States, and arrive at Narita International in Tokyo, Japan. IAD 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.
Near Washington, also compare DCA (Washington), BWI (Baltimore). 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.
