The reality of the Japanese situation cool&thegang, is that the Japs do NOT honor the contract.
The salaries, allowances, and bonuses are so far removed from those of the Jap pilots, that foreign pilots should be classified as POW's (pilots of the West?) instead of skilled labor!
Japanese pilots are strongly unionised for good reason - to protect themselves from their unscrupulous, unprincipled employers!
Combine this with the problems of not being issued a Resident Visa for Jap Land, and hence not paying tax there - or anywhere else. There have been several references to this on other forums of late that should alert pilots that they might be setting themselves up, big time, for a close encounter with the taxman.
If you are willing to accept this job, knowing full well that you will have to halve the advertised salary to allow for personal income taxation, you will then realise that it is "just another low paid job in just another Asian country". with the exception being this Asian country is one of the most expensive countries in the world, in which to live.
Until the Japs are made to tell the truth, and honor the contract, you would be well advised to give this one a very W I D E berth!
