We seem to be going in circles on this thread.
There is a lot of good information on T&C, quality of life etc. in this thread.
How ever the issue of training and specifically the length of training keeps popping up in various questions and theories about possible workarounds.
Forget it people, there is no way around it. This is a very good gig and the price af admission is 6-8 month in Tokyo/Narita getting used to the lokal way of doing things, typed and checked to line.
I realize this can be difficult to grasp if one works someplace where a type rating can be done in 2 weeks, but thats not the case here.
My advise for anyone interested in this job is to sit down with Your loved ones and find out if You have the support to do this.
Sincerely
HD
