This fare prices at 110,000 United MileagePlus miles for a one-way business class ticket from LAX to NRT on September 6, 2026. The taxes and fees are minimal at just $6, making this a clean redemption if you have the miles on hand.

For context, business class awards on this transpacific route typically run around 140,000 miles through United's dynamic pricing. That puts this fare roughly 30,000 miles below the going rate—a solid discount for a popular destination during a pleasant time to visit Japan.

One important caveat: there's only one seat available at this price. That makes this a better fit for solo travelers rather than families, unless you're able to find additional availability on connecting itineraries or different dates.

If you're flexible and have been sitting on a MileagePlus balance, this is a reasonable opportunity to book a comfortable flight to Tokyo without paying the premium rates that often appear on this corridor.
