Delta and United have $488 posted through their websites.

This is probably a consolidator fare and possibly may not earn miles. A quick check of times shows this is American Airlines nonstop flights.

While this is a $250 discount on the fare AA is charging for the same flight, the catch is the return flight is one-stop via Dallas DFW with a 12 hour all-day layover in Dallas before the flight back to LAX. Great fare, but not a good itinerary. Check these low fare deals carefully, since they are not always the best deal when money saved is compared to other flight options available for less than $50 more.
Momondo.com also pulls up Star Alliance discount fares for some dates to drop the price to around $450 round trip.
I see low United fares available for $486.66 departure as late as March 30, 2017 with return flights in April and nonstop both ways.
This is one of the best deals I have seen for Tokyo in the past year. China Eastern has had fares this low, but that means a stopover in China. These nonstop low fare flights are a good low fare opportunity for LAX to Tokyo.
