United is showing business class award availability from San Francisco (SFO) to Tokyo Narita (NRT) on April 12, 2026, for 110,000 MileagePlus miles. The taxes and fees are minimal at just $6. This is a solid option for anyone planning a spring trip to Japan.
For context, business class awards on this route typically price at around 140,000 miles through United's dynamic pricing model. At 110,000 miles, you're saving roughly 30,000 miles compared to the usual rate. That's a meaningful difference, especially if you're working toward other redemptions.
There's only one seat available at this price, so this won't work for families traveling together. However, if you have a solo traveler in your household or are looking to position someone for a larger trip, it could be a practical use of miles. April is also a lovely time to visit Japan, with cherry blossom season typically in full swing.
As with all United awards, availability can disappear quickly. If this fits your travel plans, it's worth booking sooner rather than later. You can always cancel and redeposit the miles if your plans change, though redeposit fees may apply depending on your MileagePlus status.
