Tokyo is a route that infrequently goes on sale, so this $690 airfare on Air China caught my eye today. The ticket routes via Beijing, but reasonable connection times of a couple hours can mean a quick transit. The next lowest fare is $835 with other Star Alliance carriers, including United or ANA nonstop and Delta matching with its own nonstop $835 flight.
Air China low fare departure dates at $690 run from late August to mid-December 2015.

Air China is bookable on the airline website. I have an image from Priceline simply for better display format of the itinerary.
Air China economy U class earns 50% flight miles in United Mileage Plus as redeemable miles and elite qualifying miles at 7,580 miles for these round trip flights, which is more miles than most elites would earn flying United Airlines.
