JAL 787-900 First Class? Award Ticket Available for 80,000 AA miles

Hi All,

Does anyone know what the First Class product on JAL 787-900 is? Flight i'm looking at is NRT-LAX. I thought that First Class was only available on the A350 and B777. Is this a mistake on AA's part? Business class is available for 60k AA miles and First Class is available for 80k AA miles. TIA!
