This fare prices at roughly 30,000 miles less than the ~140,000 miles United typically charges for business class between Los Angeles and Tokyo. With minimal taxes and fees, it's a solid use of MileagePlus miles for a summer trip to Japan.
The catch: only 2 seats remain on the July 8, 2026 departure. That makes this better suited for a solo traveler or a couple than a full family, but it's worth checking nearby dates to see if similar availability exists.
July is peak season for Japan travel, which makes finding any business class award space noteworthy. Temperatures will be warm and humid, but you'll catch the tail end of summer festivals if that appeals to you.
One practical tip: if you don't have enough MileagePlus miles, remember that United allows you to combine miles with a co-branded cardholder or transfer Chase Ultimate Rewards points at a 1:1 ratio.
