Actually ANC is hiring like mad since splitting from ANA. If you are native Japanese and don't mind doing the conversion, they will hire you conditionally before you are finished with the JCAB conversion. 747 FO.
ANA doesn't hire any foreigners. ANK from time to time will.
If you have any desire to fly in Japan, talk to Fred Hagihara at http://www.twiit.com
