Why? This aircraft is clearly marked with both the "Air Japan" and the "ANA" logos. I have not seen any indication as to the nationality of the flight deck crew.
Except for the fact that you have 4 to 5 employees who actually work at Air Japan telling you that we don't operate NH 954. It is solely operated by ANA mainline.
All of ANA's 767-300ERs are marked with "Air Japan". Sometimes they have J's flying them, sometimes not.
