- February 2027 is the cheapest month to fly over the next six months, with round trips from $395; September 2026 is the most expensive at $518 and up, a difference of $123 per traveler.
- Departing on a Wednesday averages 17% less than a Sunday on this route. If your dates are flexible, shift the outbound by a day or two and check the calendar view before you book.
- Book 2 to 5 months ahead for the best fares; long-haul seats sell out earliest for summer and holiday travel.
- Tokyo is 16 hours ahead of Seattle. Expect to lose 16 hours on the clock heading east, so an overnight or late-afternoon departure tends to arrive at a more usable hour.
Destination guide
Tokyo: The world's biggest city, effortlessly polite
Tokyo is reachable nonstop from a dozen US cities via Haneda (close to the city) and Narita. A weak yen has made Japan a value destination, and Tokyo's food, neighborhoods, temples and the bullet train to Kyoto make it the trip of a lifetime.
Best time to visit: Late March–April (cherry blossoms) and October–November (fall color) are the best and busiest. May and September are pleasant; summer is hot and humid with typhoons possible; winter is dry, clear and cheap.
