No chance at all
ANA as well as Japan Airlines hire only cadets that they train from the beginning
Even if you are Japanese and you did your training in America (exemple) and you have 3000 hours ,ANA and Japan Airlines WILL not hire you
As a Japanese in that case you may be hired by Skymark. Air Do, Skynet ect ect
One thing I learnt, especially in this business, is never say never! Also considering that the aviation scene will change drastically in the next few years with all these LCC starting.
But it's true, as it is right now, no chance.
