Give it some time Lear. You'll find the Japanese are absolute masters at passive aggresive behaviour. Once you are in it thick you'll find a knife in your back and the person who put it there smiling politely at you. Just a few words of advise: Never Ever open up to them or tell them anything they could conceivably use against you in the near or distant future. Remember that everything and I mean everything gets written down and will be used against you if the need arrises. Despite their outward behaviour the ANA pilots don't want foreigners at their company. If they say otherwise they are lying to you. Get used to that to, they will lie to you and not feel shame for it. Just cover your butt and as long as you like flying, do that and then go home to your family.
Before you ask, I am a current contract pilot flying for a Japanese company and plan to be till retirement. I don't have any axes to grind, I just figured out the truth and made peace with the reality of flying here.
