American has applied to begin daily non-stop service between Los Angeles and Tokyo-Haneda on January 15, 2015. It is unclear if it would replace Los Angeles-Narita service. The proposed schedule uses the flight numbers AA 169/170, which suggest it might, but the actual proposal submitted to DOT does not make mention of it.
AA 169 LAX 1705-2200+1 HND 772 Daily
AA 170 HND 0130-1825-1 LAX 772 Daily
Delta seasonally suspended it's Seattle-Haneda route yesterday, and American is making the argument the slot should be transferred, while Delta will attempt to keep it dormant.
