This Los Angeles to Tokyo Narita route is currently pricing at 55,000 MileagePlus miles one-way in economy, compared to the typical 60,000 miles you'd normally see. That 8% savings may not be dramatic, but for a family of four, you're looking at 20,000 miles back in your pocket—enough for a domestic one-way.
Availability appears wide open around the July 15, 2026 travel date, which is notable since peak summer travel to Japan tends to book up quickly. The $6 tax and fee total is about as low as you'll find on transpacific awards.
If you're flexible, it's worth searching a few days in either direction to confirm pricing holds steady. Award rates on this route can fluctuate based on demand, so locking in now makes sense if your summer plans are taking shape.
One practical tip: Tokyo Narita is farther from central Tokyo than Haneda, so factor in the Narita Express or airport bus when planning your ground transportation. The train takes about an hour to reach Tokyo Station.
