United and ANA have code-share round-trip flights from Seattle (SEA) to Tokyo (HND/NRT) for $586-$619, NONSTOP. Flights January to May. No Wednesday departures. 7-day minimum stay required.
This work as an Open-Jaw. Which means, you can fly into Tokyo, nonstop, and return from Osaka (KIX/ITM).
Open-jaws are better than round-trips, if you want to visit both Tokyo and Osaka on your Japan trip, because you don’t have to backtrack to Tokyo for your return flight.
Here’s an example how I would set one up (see screenshot). SEA-HND on Jan 31 – ITM-SEA Feb 07. You’ll have to experiment and find other Open-jaws on your own.
