@pacificdream...., The preliminary information that I have thus far is that there are 3 schools in Japan that will see you thru the ATPL but the first stumbling block is that training is done in Japanese.
And as I said before.., flight hour is upwards of $500...!
Not sure this is the best use of resources to get a job here though..! Right now there are a few jobs available in Japan..., just start applying and even if you don't get the job you wanted, all of them will take you through the process of obtaining your ATPL.., remember that Japan is not like China, there are no restrictions once you have your license to apply at any other job.
