When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 19 hours outbound, on a 16-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $887 for 10,908 km each way, that works out to about $41 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 30 departure cities we track at a similar distance from Tokyo, this fare ranks 24th — 50% above the $592 from Milan. That puts it in the cheaper half of the 20 routes of similar length we watch out of Washington, where the middle fare is $887. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Tokyo: Mar–May · Oct–Nov.

Good to know
WAS → TYO, answered.
How far in advance should I book WAS → Tokyo?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Washington to Tokyo?
The current cheapest fares involve a connection, ticketed under Frontier Airlines. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
