This fare prices out at 110,000 MileagePlus miles for a one-way business class ticket from LAX to NRT on April 21, 2026. The taxes and fees come in at just $6, which is as low as you'll see on a transpacific award.
For context, United typically charges around 140,000 miles for business class between Los Angeles and Tokyo. That makes this a solid 30,000-mile savings per ticket. If you're sitting on a MileagePlus balance and have flexibility for late April travel, this is a reasonable use of miles.
Availability is limited to just 4 seats, so this works for solo travelers or couples but probably won't accommodate larger families on a single booking. If you're traveling as a group, you may want to search for each pair of passengers separately.
One practical note: April is a popular time to visit Japan due to cherry blossom season, which typically runs through mid-April. By the 21st, you may catch the tail end of blooms in northern regions like Tohoku, though peak viewing in Tokyo will likely have passed.
